Overview

Introduction The MSR 20-1X routers are multifunctional access routers which are oriented to small and medium business (SMB), enterprise branches, and home offices, and are designed to serve high-quality orderwire and commercial networks. High-quality orderwire and commercial networks need to satisfy the requirements for broadband access, wireless access, voice access, VPN, and QoS. In addition, the network devices require high performance, stability, security, and manageability. MSR 20-1X routers are cost effective. They provide different integrated communication interfaces for different communication links and also provide an SIC/DSIC slot for expansion.

The MSR 20-1X routers include MSR 20-10, MSR 20-11, MSR 20-12, MSR 20-13, and MSR 20-15. All of them can be placed on a tabletop, or installed on a wall or in 19-inch standard cabinet. The following sections will give you more details about these four models.

NOTE:

• The console port and AUX port of MSR 20-1X routers share one RJ-45 interface.

• Two SIC slots can form one DSIC slot.

• MSR 20-12 and MSR 20-15 can implement voice data processing without any VCPM card. If you needvoice support, insert a VPM card into the VPM slot on the main control board, and then install a SIC-1VE1 or SIC-1VT1 on the router.

• Only MSR 20-12 and 20-15 can support SIC-1VE1 and SIC-1VT1.

• MSR 20-12, MSR 20-13, and MSR 20-15 all include two sub-models. One sub-model supports WLANand the other does not. You can purchase the appropriate sub-model as required.

• The Boot ROM stores the Bootstrap for booting the router.

• The memory stores the communication data between the system and the CPU during the system operation.

• The flash memory stores the BootWare, the software system and the configuration file of the router.

• Do not unplug the USB device during USB data transmission; otherwise, data loss or even hardware failures may occur.

• The wireless module can not be purchased separately.

• By default, the impedance of the fixed E1 interface on MSR 20-12 is 75-ohm. Using the internal DIP switches, users can change the interface impedance from 75-ohm to 120-ohm. For detail information, refer to Chapter 6 “Hardware Maintenance”.

Generic Modules The generic modules provided for the MSR 20-1X routers include SICs. For detailed information about interface cards, refer to MSR Series Routers Interface Module Manual.

For the types of interface modules that each model of the MSR 20-1X routers can accommodate, refer to Appendix A Interface Card and Interface Module Purchase Guide in the MSR Series Routers Interface Module Manual.

12

SICs and DSICs MSR 20-1X routers adopt modular design and provide the following interfaces to support a wide range of optional SICs/DSICs:

• Synchronous/asynchronous serial interface

• Ethernet port

• E1/T1 interface

• ISDN BRI/PRI

• ADSL interface

• Voice interface

• Layer 2 Ethernet interface

13

Installation Preparations

Requirements on Environment MSR 20-1X routers are designed for indoor application. To ensure the normal operation and prolong their service life, the installation site must meet the requirements mentioned in the following sections.

Requirements on Temperature and Humidity To ensure the normal operation and prolong their service life, the temperature and humidity in the equipment room shall maintain at a certain level. A long-term high relative humidity will quite likely result in poor insulation performance, electric leakage, mechanical property change, and corrosion, while a low relative humidity will result in looseness of fastening screws owing to shrinkage of insulation washers, or electrostatic discharge (ESD), which may damage the CMOS circuit on the router. A high temperature will speed up the aging of insulation materials, and thus will greatly lower the reliability of the router and shorten the service life.

Table 12 lists the requirements on the temperature and humidity for MSR 20-1X routers.

Table 12 Temperature and humidity requirements in the equipment room

Temperature Relative Humidity

0°C to 40°C (32°F to 104°F) 5% to 90% (noncondensing)

Requirements on Cleanness Dust is harmful to the safe operation of the router. Dust on the chassis may result in static absorption, causing poor contact between metal connectors or joints, which may not only shorten the service life of the router, but also bring about communication failures. Especially under the condition of a low indoor humidity, dust is easier to be absorbed.

Table 13 lists the requirements on the dust concentration and diameters in the equipment room.

Table 13 Limitation on dust concentration and diameters in the equipment room

Diameter (μm) 0.5 1 3 5

Concentration (particle/m³) 1.4 × 107 7 × 105 2.4 × 105 1.3 × 105

Besides, the contents of salt, acid, and sulfide in equipment room shall be strictly restricted. Harmful gases will accelerate the corrosion of metal parts and the aging of some parts. Table 14 lists the concentration limit of SO2, H2S, NH3 and CI2 in the equipment room.

Table 14 Concentration limit of some harmful gases in equipment room

Gas Concentration limit (mg/m3)

SO2 0.2

H2S 0.006

Gas Concentration limit (mg/m3)

NH3 0.05

Cl2 0.01

Requirements on Electrostatic Discharge Prevention Although many antistatic considerations have been given to MSR 20-1X routers, damage to circuits or even the routers may still happen when the amount of static charges exceeds a certain limit.

In the communication network to which the routers are connected, static induction mainly comes from two aspects: the external electric field (such as outdoor high voltage power line or thunder) and the internal system (such as indoor environment, floor materials or the router equipment structure. Thus, the following should be considered to safeguard the equipment against ESD.

• Make sure that the router and the floor are well grounded.

• The equipment room is dust-proof.

• Maintain an appropriate humidity and temperature.

• Wear an ESD-preventive wrist strap and uniform when contacting a circuit board.

• Place the removed circuit board on an antistatic workbench, with its face upwards, or put it into an antistatic bag.

• When observing or moving the removed circuit board, it is only allowed to touch the edge of circuit boards, instead of elements on the circuit board.

Requirements on Electromagnetic Environment The interference sources, no matter where they come from, affect the routers in the form of capacitance coupling, inductance coupling, radiation of electromagnetic wave, and common impedance (including the grounding system) coupling. Therefore, the following should be considered:

• Take effective measures to prevent the power system from being interfered by the power grid system.

• Separate the return terminal of the router from the grounding device or lightning protection grounding device of the power supply equipment and keep them as far as possible.

• Keep the router far away from radio stations, radar, and high-frequency devices working in high current.

• Use electromagnetic shielding when necessary.

Requirements on Lightning Protection Although many measures have been taken to protect MSR 20-1X routers from lightning, if the lightning intensity exceeds a certain range, damage to the router may still happen. To protect the router from lightning better, the following should be considered:

• Ensure the PGND wire of the chassis is well grounded.

• Ensure the grounding point of the AC power socket is well grounded.

• Install a lightning arrester at the input end of the power supply to enhance the lightning protection capability of the power supply.

• Install a special lightning arrester at the input end of outdoor signal lines (for example, ISDN line, telephone line, and E1/T1 line) to enhance the lightning protection capability.

15

Checking the Rack When installing MSR 20-1X routers, make sure that:

• There is spacing reserved at the air inlet and exhaust in the router for the purpose of heat dissipation of the router chassis.

• The rack has a good ventilation system for heat dissipation.

• The rack is solid enough to support the weight of the device and the installation accessories.

• The rack is well-grounded.

Safety Precautions Routers play an important role in data communications network. Please pay attention to the following signs:

WARNING: Means the reader be extremely careful. Improper operation may cause bodily injury.

CAUTION: Means the reader be careful. Improper operation may cause data loss or damage to equipment.

When installing or working on the router, observe the following recommendations:

• Keep the router far away from heat sources and dampness.

• Ground the router correctly.

• Wear an ESD-preventive wrist strap, making sure that the strap has good skin contact.

• Do not insert or remove interface modules or interface cards of the router when the power supply is connected.

• Do not insert or remove a cable when the power supply is connected.

• Connect the interface cables correctly for the router. Do not connect a telephone line (including ISDN line) to a serial port.

• Use laser with caution. Do not directly stare into apertures or fiber-optic connectors that emit laser radiation.

• Equip an uninterrupted power supply (UPS).

Installing Generic Modules For the procedure for installing generic modules, including various smart interface cards (SICs), refer to MSR Series Routers Interface Module Manual.

Connecting the PGND Cable

WARNING!

Correctly connecting the protection grounding (PGND) cable is crucial to the lightning protection and electromagnetic susceptibility (EMS) of your router. You must correctly connect the PGND cable when installing or using the router.

The power input end of the router is equipped with a noise filter. The neutral ground of the power input end is directly connected to the chassis and called PGND (also known as chassis ground). The PGND must be well grounded so that induced current and leakage current can be safely led to the ground and the EMS of the router can be reduced. The PGND cable can also protect the router against high lightning voltage resulting from external network lines such as E1/T1 line or ISDN/PSTN line.

The protection grounding terminal marked with a grounding label is located on the rear panel of the chassis, as shown in the following figure:

21

Figure 16 Protection grounding terminal of the router

Use a PGND cable to connect the protection grounding terminal to the ground, with the grounding resistance not greater than 5 ohms. Likewise, if the router is installed in a 19-inch standard cabinet, the cabinet shall also be well grounded.

WARNING!

The router in operation must be well grounded. Otherwise, the router cannot be protected against lightning, and consequently, the router or even the peer device may be damaged.

Connecting the Power Cord MSR 20-1X routers support AC power input only.

The figure below shows the appearance of the power socket on the router:

Figure 17 Appearance of the AC power socket on the router

(1) Power switch (2) AC power socket

22

Recommended AC power connector

A three-terminal, single-phase power connector with a grounding contact is recommended. Normally, the grounding contact of the power supply system in a building was buried during construction and cabling. Before connecting the AC power cord, you must make sure that the power supply of the building has been well grounded.

Connecting the AC power cord

Step1 Make sure that the PGND is securely connected to the ground.

Step2 Move the power switch of the router to the OFF position, and connect one end of the power cord shipped with the router to the power socket on the rear panel, and the other end to an AC power source.

Step3 Move the power switch to the ON position.

Step4 Check whether the power LED on the front panel of the router is ON. If the power LED is ON, the power cord is properly connected.

Installing Antennas Fasten the attached antennas onto the router. Avoid over-tightening. Once the network is up and running, you may need to adjust the antennas to achieve better coverage. Usually, the antennas should be vertical to the ground or ceiling to achieve the optimal coverage, as shown in the following figure.

Figure 18 Installation of router antenna

CAUTION:

Do not touch the antenna top, especially after the antenna is connected with the grounding contact. Otherwise electrostatic discharge (ESD) may damage the router.

Ethernet cable

Electrical Ethernet interfaces usually use category-5 twisted pair cables to connect Ethernet networks, as shown in the following figure:

Figure 20 Ethernet cable

Ethernet cables fall into the following two categories:

• Standard cable, also called straight-through cable. At both ends of a standard cable, wires are crimped in the RJ-45 connectors in the same sequence. A straight-through cable is used to connect a terminal device (for example, a PC or router) to a hub or LAN Switch. The cables delivered with the router are standard cables.

• Crossover cable. At both ends of a crossover cable, wires are crimped in the RJ-45 connectors in different sequences. A crossover cable is used to connect a terminal device (for example, PC or router) to another terminal device. You can make crossover cables by yourself.

NOTE:

In making network cables, shielded cables are preferred for the electromagnetic compatibility sake.

Connecting the Ethernet cable

Follow these steps to connect an Ethernet cable:

Step1 Connect one end of the Ethernet cable to an Ethernet interface on the router and the other end to the peer device. For a 10/100 Mbps Ethernet interface that supports MDI/MDIX autosensing, you can use a straight-through cable or crossover cable to connect the interface to a hub or LAN Switch.

Step2 View the LINK LED of the Ethernet interface. If the LINK LED is ON, a link is present. If the LINK LED is OFF, no link is present. In the latter case, check the line.

Connecting the AUX Interface to a Modem AUX interface

The AUX interface is an RS232 asynchronous serial interface, which can serve as a backup interface of a WAN interface and provide dial connection. In case of console failure, the AUX interface can function as the console interface.

AUX cable

The AUX cable is an 8-core shielded cable. An RJ45 connector is equipped at one end and is connected to the AUX interface. A DB25 male connector and a DB9 male connector are equipped at the other end and one of them is connected to the serial interface of the Modem.

Figure 22 AUX cable

Connecting the AUX cable

Follow these steps to connect the AUX cable.

Step1 Plug the RJ-45 connector of the cable into the AUX interface on the main control board.

Step2 Plug the DB-25 or DB-9 connector into the serial interface on the analog Modem.

When using the AUX interface for remote configuration or dial backup, you need to connect the local Modem to the remote Modem over PSTN and then to the remote device. For the configuration procedure, refer to MSR Series Routers Configuration Guide.

MSR 20-1X routers provide various interface cards and interface modules. For detailed information, refer to MSR Series Routers Interface Module Manual.

Configuration Fundamentals In general, the router configuration steps are as follows:

33

Step1 Before configuration, you should make specific network requirements, including the objective, role of the router in the network, division of subnets, WAN type and transmission medium, network security policy and reliability.

Step2 Based on the above requirements, draw a clear, complete network diagram.

Step3 Configure the WAN interface of the router. First, configure the operating parameters (for example, the operating mode of the serial interface, baud rate and synchronous clock) of the interface according to the transmission medium of the WAN. For a dialer interface, you also need to configure DCC parameters. Then, configure the link layer protocol encapsulated on the interface and corresponding operating parameters.

Step4 Configure the IP addresses or IPX network numbers of all the interfaces on the router according to the division of the subnets.

Step5 Configure the routes. If it is necessary to enable a dynamic routing protocol, you should configure related operating parameters of the protocol.

Step6 If special security is required, perform the special security configuration for the router.

Step7 If special reliability is required, perform the special reliability configuration for the router.

For the configuration details of the protocols or functions of the router, refer to MSR Series Routers Configuration Guide.

Command Line Interface Functions of the command line interface

The command line interface (CLI) of MSR 20-1X routers provide a number of configuration commands, which can be used to configure and manage the router. The CLI provides the following functions:

• Allows you to perform the local configuration through the console interface.

• Allows you to perform the local or remote configuration and directly log in to other routers for the management purpose by using the telnet command.

• Provides online help after you enter “?”.

• Provides network diagnostic tools, such as Tracert and Ping, to quickly diagnose the availability of the network.

• Provides all kinds of detailed debugging information to help diagnose network faults.

• Provides a command line interpreter, which adopts fuzzy search for the keywords of the command. If you enter a conflict-free keyword for a command, the command will be interpreted accordingly. For example, for a display command, you can just enter dis and the command will be interpreted.

Command line interface view

The command line interface of MSR 20-1X routers provide plenty of configuration commands. All the commands are grouped in system view. Each group corresponds to a view. You can use commands to switch between different configuration views. In general, only certain commands can be executed in a particular view. But some common commands (such as ping and display current-configuration) can be executed in any view.

34

Slot Arrangement and Rules for Numbering Interfaces Slot arrangement

The MSR 20-1X routers provide many types of interfaces, such as console, AUX, Ethernet, serial interface (synchronous/asynchronous), and asynchronous interface. The following describes how these interfaces are numbered.

Rules for numbering interfaces

The interfaces of the MSR 20-1X routers are numbered with “two dimensions”:

• The interfaces are represented by interface-type X/Y, where interface-type can be serial, asynchronous, or Ethernet, X specifies the slot number and Y specifies the interface number.

• Fixed interfaces are on Slot 0 and the expansion slot is defined as Slot 1.

• Different interfaces on an interface module share the same slot number X.

• For each interface, Y starts from 0 indicates the interface sequence on the interface module, from left to right.

If you install an SIC-4FSW in slot 1 on the MSR 20-11, the Ethernet interfaces are numbered as follows:

• Layer 3 Ethernet interface is numbered Ethernet 0/0;

• The Layer 3 Ethernet interfaces on the SIC-4FSW module are numbered Ethernet 1/0, Ethernet 1/1, Ethernet 1/2, and Ethernet 1/3.

Software Maintenance

Introduction

Files Managed by the Router BootWare file

The BootWare file is used to boot an application. A complete BootWare file includes two segments: basic and extended.

Application files

By default, the MSR 20-1X routers define three application files for booting: main, backup, and secure. The system selects these three files in sequence to start up the router. Currently only one application file is stored in the Flash memory of the MSR 20-1X routers due to limited memory size. To change the file selection sequence or modify an application file, refer to Maintaining Application and Configuration Files on page 55 for details.

The details about the three application files are as follows:

• Main file: The file used for booting by default. The default file name is main.bin and the file type is M.

• Backup file: The default file name is backup.bin and the file type is B. The system uses the backup file when it fails to boot using the main file.

• Secure file: The default file name is secure.bin and the file type is S. The system uses the secure file when it fails to boot using the backup boot file. If the system fails to boot using the secure boot file, it prompts a boot failure.

NOTE:

• The application files for system boot can be type M, B, and S, but not type N (namely, types other thantype M, B, or S).

• You can modify the name of an application file in storage after the application file is loaded. You cannotmodify the type of a type S application file, but you can modify the type of a type M, B, or N applicationfile using the BootWare menu or using commands after the application file is loaded.

• The secure file is the last resort for system boot. You can download it in the BootWare menu and must name it secure.bin. However, you cannot modify the type of this file or change the type of other files toS. If you change the name of the secure file with the rename command after system boot, the file is removed from the Flash memory and you need to download it again.

• You can store type M, B, S files in storage devices, but only one for each type in each storage device. Forexample, if a type M+B file exists in the Flash memory, there will be no type M or B file. If you changethe type of a file to B, the M+B file will become a type M file.

Configuration files

The configuration files store configuration information of the router.

36

By default, the system defines three configuration files for booting: main, backup, and default file. If the three configuration files are loaded in a storage device, the system selects them in sequence until the router is successfully loaded. To change the sequence of these configuration files or modify them, refer to Maintaining Application and Configuration Files on page 55.

The details about the three configuration files are as follows:

• Main configuration file: The configuration file used for booting by default. The file type is M.

• Backup configuration file: The file type is B. The system uses the backup configuration file when it fails to boot using the main configuration file.

• Default configuration file: The file type can be M, B, or N. The system uses the default configuration file when it fails to boot using the backup configuration file. If the system fails to boot using the default configuration file, it boots with null configuration. The name of the default configuration file varies with router brands. The main and backup configuration operations on the default configuration file are the same as those on common configuration files.

NOTE:

• The configuration file for system boot can be a main configuration file, a backup configuration file, or default configuration file of type N, but not non-default configuration file of type N (namely, neither typeM nor type B).

• You can modify the file name of a configuration file in the Flash memory using a command after the configuration file is loaded. You cannot modify the type of the default configuration file, but you can modify the type of a type M, B, N configuration file in the BootWare menu, or using commands after theconfiguration file is loaded.

You can store type M and B configuration files in the flash memory, but only one for each. For example, if a type M+B configuration file exists, there will be no type M or B file. If you change the type of a configuration file to B, the M+B configuration file will become a type M file.

CAUTION:

• A file name can contain at most 64 characters (including drive letter and a string terminator). If the driveletters are “FLASH:/”, the file name can contain at most [64-1-7 ] = 56 characters; otherwise errors willoccur in file operation. Typically, a file name is recommended to be less than 16 characters.

• Extended ASCII characters (ASCII>=128) and invisible characters (ASCII<33) should not appear in a file name.

• The following characters should not appear in a file name: ”, ‘, ?, \, space, *, |, <, /, :, >, and ~.

• The dot “.” can appear in a file name, but not at the head or the end of the file name. Two consecutivedots are not allowed.

Software Maintenance Methods • Upgrade BootWare and an application using the XModem protocol through a serial port.

• Upgrade an application from a TFTP/FTP server through an Ethernet interface in BootWare.

• Upload/download an application and configuration file from a TFTP/FTP server via command lines.

37

NOTE:

• The BootWare program is upgraded together with the Blinux application program. You do not need toupgrade the BootWare separately. When upgrading the Blinux program, the system checks whether therunning BootWare version is consistent with that in the updating host application program. If inconsistent, the system asks whether to upgrade the BootWare. If you make no choice within one second, the system upgrades the BootWare automatically.

• When the flexible interface platform (FIP) starts, it automatically checks the running BootWare version.If the current version is inconsistent with the version used on the FIP, the system upgrades the BootWareautomatically.

• Check the current version of BootWare and application program before upgrade. For the version configuration information, see the corresponding Release Notes.

Maintaining Application Program and Configuration Through Command Lines

After the router is booted, you can upgrade and back up an application program, and back up and restore configurations through command lines.

38

Maintaining the Router Through TFTP Server In the TFTP service, the router is TFTP client and the file server is the TFTP server. You can enter commands on the terminal to upload or download configuration files or application programs to or from the file server.

Setting up a configuration environment

Set up a hardware environment (refer to Upgrading an Application Program Through an Ethernet Interface on page 47 for details), and point the server path to the directory where the file is stored.

Figure 33 Network diagram for maintenance through command lines

Configure the IP addresses of both sides on the same network. For example, the IP address of the TFTP server is set to 192.168.0.1, and that of the Ethernet interface connected to it (Ethernet 0/0 in this example) is set to 192.168.0.2. Use the ping command to check whether the connection successful.

Backing up and restoring application programs and configuration files

After setting up the environment, perform the following operations on the console terminal:

Use the dir command to view the files in the current file system: <SYSTEM>dir

Directory of flash:/

If a startup.cfg file already exists in the router, the system prompts you whether to overwrite it. You can type Y or y to overwrite it.

Upgrading the application programs

After setting up the environment, perform the following operations on the device (the application name is msr.bin for example):

Use the save command to save the current configuration: <SYSTEM>save

The current configuration will be written to the device. Are you sure? [Y/N]:y

Please input the file name(*.cfg)[flash:/startup.cfg]

(To leave the existing filename unchanged, press the enter key):

<SYSTEM>

Make sure that the configured startup file is correct, and then use the reboot command to reboot the device: <SYSTEM>reboot

Start to check configuration with next startup configuration file, please

wait.........DONE!

This command will reboot the device. Current configuration may be lost in next

startup if you continue. Continue? [Y/N]:y

After the device is rebooted, use the display boot-loader command to view the startup file information of the device to make sure that the current application of the device is msr.bin.

CAUTION:

• When you back up a file, the file will directly overwrite the one with the same name on the server.

• The backup configuration file can be modified by a text editor. You can change the configuration by downloading the modified configuration file and the modification takes effect after you reboot the router. Similarly, you can also upgrade the main application file by downloading a new application fileto overwrite the original main application file.

• The above operations are performed in user view.

• Before upgrading an application, save the current configuration of the device.

• When upgrading an application, use the dir command to view the size of the downloaded file and whether the file is the same as that on the server to ensure that the application is complete and correct.

Maintaining the Router Through FTP Server Maintaining the router serving as the FTP server

File Transfer Protocol (FTP) is an application-layer protocol in the TCP/IP protocol suite. It is mainly used for file transfer between remote hosts. Over TCP, FTP provides reliable and connection-oriented data transfer service, but does not provide any access authorization and authentication mechanism.

In the FTP service, the router can serve as the FTP server. You can run the FTP client to log in to the router access files on the router.

Before using FTP, you need to install the FTP client. No FTP client is shipped with the H3C MSR 20-1X routers. In the following example, the FTP client application program is the built-in Windows XP FTP client.

Step1 Set up a hardware maintenance environment, as shown in the following figure:

41

Figure 34 Maintain the router serving as the server

Ethernet cable

Router

PCConsole cable

TFTP/FTP Server

TFTP/FTP Client

Configure the IP addresses of both sides on the same network. In this section, the IP address of the FTP server (PC) is set to 192.168.1.1, and that of the connected Ethernet interface on the router (Ethernet 0/0) is set to 192.168.1.2. Use the ping command to check the connectivity.

Step2 Enable the FTP service.

After configuring authentication and authorization, you can enable the FTP service. The FTP server supports multi-user access. Upon receiving the request from a remote FTP client, the FTP server executes an action accordingly and returns the execution result to the client. Use the following command to enable the FTP service: [SYSTEM]ftp server enable

% Start FTP server

Add an authorized username and password: [SYSTEM]local-user guest

[SYSTEM-luser- guest]service-type ftp

[SYSTEM-luser- guest]password simple 123456

Step3 Maintain the router.

After enabling the FTP service and configuring the username and password, you can enable the FTP client on the PC. In the following example, the FTP client application program is the built-in Windows XP FTP client.

Type ftp in the DOS window, and the system prompt is changed to ftp>: C:\Documents and Settings\Administrator>ftp

ftp>

ftp> open 192.168.1.2

Connected to 192.168.1.2.

220 FTP service ready.

User (192.168.0.2:(none)): guest

331 Password required for guest

Password:

230 User logged in.

42

After you correctly enter the username and password, the system prompts login success. You can then maintain the router, for example, modify transmission mode and local path, and back up files. In this example, the main.bin file on the router is copied to the PC. ftp> binary

200 Type set to I.

ftp> lcd c:\temp

Local directory now C:\temp.

ftp> get main.bin main.bin

200 Port command okay.

150 Opening BINARY mode data connection for main.bin.

226 Transfer complete.

ftp: 14323376 bytes received in 16.81Seconds 851.87Kbytes/sec.

Use the following command to recover the backup file to the router: ftp> put main.bin main.bin

200 Port command okay.

150 Opening BINARY mode data connection for main.bin.

226 Transfer complete.

ftp: 14323376 bytes sent in 8.29Seconds 1727.37Kbytes/sec.

ftp> quit

221 Server closing.

Maintaining the router serving as a client

You can also maintain the router file system by setting up an FTP environment where the router serves as an FTP client.

Step1 Set up a maintenance environment.

Figure 35 Maintain the router serving as a client

The router serves as the client, while the PC running FTP server program serves as the FTP server. Set the FTP server path and add username and password for the router.

43

Configure the IP addresses of both sides on the same network. In this section, the IP address of the FTP server is set to 192.168.1.1, and that of the connected Ethernet interface on the router (Ethernet 0/0 in this example) is set to 192.168.1.2. Use the ping command to check the connectivity.

Step2 Maintain the router through the terminal connected with the console interface of the router.

The following gives an example: <SYSTEM>ftp 192.168.1.1

Trying 192.168.1.1 ...

Press CTRL+K to abort

Connected to 192.168.1.1.

220 3Com 3CDaemon FTP Server Version 2.0

User(192.168.1.1:(none)):guest

331 User name ok, need password

Password:

230 User logged in

[ftp]

Use the following commands to maintain the router.

Here, the get and put commands are used to restore and back up files. [ftp]get main.bin main.bin

flash:/main.bin has been existing. Overwrite it?[Y/N]:y

200 PORT command successful.

150 File status OK ; about to open data connection

226 Closing data connection; File transfer successful.

FTP: 14323376 byte(s) received in 69.256 second(s) 206.00K byte(s)/sec.

[ftp]put main.bin main.bin

200 PORT command successful.

150 File status OK ; about to open data connection

226 Closing data connection; File transfer successful.

FTP: 14323376 byte(s) sent in 15.974 second(s) 896.00Kbyte(s)/sec.

[ftp]quit

221 Service closing control connection

After an application is uploaded to the device, you can use the boot-loader command to upgrade the device. For the upgrade procedure, refer to Upgrading the application programs on page 39.

• Upon upgrade failure, the system prompts “Loading failed”. In this case, please reboot the router to validate the reset IP address.

• Only Ethernet 0/0 can be used for upgrading an application program in the MSR 20-1X routers through an Ethernet interface.

Upgrading Procedure Trivial File Transfer Protocol (TFTP), a protocol in the TCP/IP protocol suite, is used to transfer trivial files between clients and the server. It provides not-so-complex and low-cost file transfer services. TFTP provides unreliable data transfer services over UDP and does not provide any access authorization and authentication mechanism. It employs timeout and retransmission to guarantee the successful delivery of data. The TFTP software is much smaller than the FTP software in size:

File Transfer Protocol (FTP) is an application-layer protocol in the TCP/IP protocol suite. It mainly transfers files among remote hosts. Over TCP, FTP provides reliable and connection-oriented data transfer service but does not provide access authorization and authentication mechanism.

Step1 Set up an upgrade environment.

Figure 36 Set up a TFTP/FTP upgrade environment

Connect Ethernet 0/0 to a PC with a crossover cable. Start the TFTP/FTP program on the PC, and set the path of TFTP/FTP server to directory of the application program. You need to set username and password if FTP server is used.

CAUTION:

No TFTP/FTP Server is shipped with the MSR 20-1X routers.

Step2 Modify Ethernet interface parameters. For details, refer to Configuring Ethernet Interface Parameters on page 48.

51

CAUTION:

• If the input file name is the same as the original one in the Flash memory, the system prompts that “Thefile is exist, will you overwrite it? [Y/N]”. Enter Y to overwrite the original file. The new application program file will then overwrite the original file of this type, ensuring the uniqueness of the applicationprogram on the device.

• Make sure the available space in the memory is sufficient. Or, the system prompts “The free space isn'tenough!”.

• The file updated will directly overwrite the original file of this type to become the only application program. The file downloaded here will overwrite the original M file and become the main boot program.

• For details of file types, refer to Files Managed by the Router on page 35.

• You can set the main or backup attribute only for the startup file in the root directory of the device.

Upgrading BootWare Through Serial Interface Use XModem to upgrade BootWare through a serial interface.

XModem Protocol Overview To upgrade the BootWare and application program through a serial interface, use the XModem protocol.

XModem is a file transfer protocol widely used for its simplicity and good performance. Modem transfers files through serial interfaces. It supports transmission of packets in 128 bytes and 1 KB, error check (checksum and CRC), and error retransmission (generally the maximum number of retransmission attempts is 10).

XModem transmission is completed by the cooperation of a receiver and a sender. The receiver sends a negotiation message to the sender to negotiate an error check method. After the negotiation, the sender starts to transmit data packets. After a complete packet is received, the receiver checks the packet using the agreed method.

52

• If the check is passed, the receiver sends an acknowledgement message to the sender. Upon receiving the message, the sender continues to send the next packet.

• If the check fails, the receiver sends a negative acknowledgement message to the sender. Upon receiving the message, the sender retransmits the packet.

Modifying Serial Interface Parameters Sometimes, we need to increase the baud rate of a serial interface to save software upgrade time, or lower the baud rate to guarantee transmission reliability. This section describes how to adjust the baud rate of a serial interface.

Enter 2 in the main BootWare menu to enter the serial interface submenu. Then, enter 5 and the system prompts for changing a baud rate. ==============================<BAUDRATE SET>==============================

|Note:'*'indicates the current baudrate |

| Change The HyperTerminal's Baudrate Accordingly |

|--------------------------<Baudrate Avaliable>--------------------------|

|<1> 9600(Default)* |

|<2> 19200 |

|<3> 38400 |

|<4> 57600 |

|<5> 115200 |

|<0> Exit |

==========================================================================


Select a proper baud rate, 5 for 115200 bps for example. The following prompt appears: Baudrate has been changed to 115200 bps.

Please change the terminal's baudrate to 115200 bps, press ENTER when ready.

Since the baud rate of the serial interface on the router is changed to 115200 bps, whereas the terminal baud rate remains 9600 bps, they cannot communicate with each other. Change the baud rate on the console terminal to the one selected for downloading software.

Perform the following configurations on the console terminal:

Figure 37 Disconnect terminal

Select File > Properties, and press Configure… to change the baud rate to 115200 bps:

53

Figure 38 Modify baud rate

Select Call > Call to establish a new connection.

Figure 39 Establish a new connection

Press Enter to view the current baud rate and return to the previous menu.

The system displays: The current baudrate is 115200 bps

NOTE:

Restore the baud rate in the HyperTerminal to 9600 bps after upgrading the BootWare. This ensures thatthe information can be displayed on the console terminal after system boot or reboot.

Upgrading BootWare First, enter 7 in the main BootWare menu (refer to Main BootWare Menu on page 43) to enter the BootWare operation submenu, through which all BootWare operations are performed. For details, refer to BootWare Submenus on page 45.

The following example illustrates how to upgrade the full BootWare:

54

Enter 3 in the BootWare operation menu. The system displays: ===================<BOOTWARE OPERATION SERIAL SUB-MENU>===================

|<1> Update Full BootWare |

|<2> Update Extend BootWare |

|<3> Update Basic BootWare |

|<4> Modify Serial Interface Parameter |


==========================================================================


Enter 1, and the system displays: Please Start To Transfer File, Press <Ctrl+C> To Exit.

Waiting ...CC

Select Transfer > Send file in the HyperTerminal window. The following window appears:

Figure 40 Send file dialog box

Click Browse… to select the application program file to be downloaded, and select XModem for the Protocol field. Then click Send. The following interface appears:

Figure 41 Sending file interface

Upon completion of downloading, the following information appears, indicating that download and upgrade succeeds: Download successfully!

425045 bytes downloaded!

Change the baud rate of the console terminal from 115200 bps to 9600 bps, and then reboot the router.

55

NOTE:

• The file name, size and path vary in different situations. Before upgrading, check the current version ofBootWare and application program.

• Restore the baud rate in the HyperTerminal to 9600 bps after upgrading the BootWare. This ensures thatthe information can be displayed on the console terminal after system boot or reboot.

Upgrading the extended BootWare involves only a segment of BootWare. Once an error occurs, you canre-upgrade BootWare.

Upgrading an Application Program Through a Serial Interface

Upgrading an application program through a serial interface is implemented under the serial submenu. Enter 2 in the main BootWare menu to enter the serial interface submenu: For details, refer to BootWare Submenus on page 45.

The following example illustrates how to upgrade a main application program.

First, change the baud rate of the serial interface to speed up upgrading ((refer to Modifying Serial Interface Parameters on page 52 for details). Then enter 2 in the serial interface submenu. The system displays: Please Start To Transfer File, Press <Ctrl+C> To Exit.

Waiting ...CC

Select an application program file and send it. The procedure for upgrading an application program through a serial interface is similar to that for upgrading BootWare. For the detailed procedure, see Upgrading BootWare on page 53.

NOTE:

Generally an application program is more than 10 MB in size. Even if the baud rate is changed to 115200 bps, it usually takes about 30 minutes to upgrade an application program. Therefore, you are recommended to upgrade an application program through an Ethernet interface.

Maintaining Application and Configuration Files You can view and modify a file type in the file control submenu:

Returning to the main BootWare menu

Return to the main BootWare menu.

Dealing with Password Loss Use the following solutions when your BootWare password, user password or Super Password is lost.

User Password Loss You cannot enter the system if you lose your user password. In this case, you can boot the system by ignoring the system configuration. Perform the following operations to set a new user password:

Step1 Enter the main BootWare menu, and enter 6 to boot the system by ignoring the system configuration.

The system displays: Flag Set Successfully.

58

The system prompts the setting succeeds.

Step2 When the main BootWare menu appears again, enter 0 to reboot the system.

Step3 Set a new password in system view. [SYSTEM]user-interface console 0

[SYSTEM-ui-console0]authentication-mode password

[SYSTEM-ui-console0]set authentication password simple 123456

The above information indicates that the password authentication is adopted on the console interface and the password is set to 123456 and stored in plain text.

NOTE:

• After reboot, the system runs the initial default configuration, but the original configuration file is storedin the Flash memory. To restore the original configuration, you can use the display saved-configurationcommand to display it, and then copy and execute it.

• If the password is stored in plain text, you can use the display current-configuration command to viewthe password in the current configuration. If you use the set authentication password cipher 123456 command to set a password, the password is stored in cipher text.

Step4 Save the new configuration. [SYSTEM] save

NOTE:

Use the save command to save your new password.

BootWare Password Loss Contact the agent or the technical support personnel to set a new BootWare password in the event of BootWare password loss.

You can modify the BootWare password under the main BootWare menu.

Enter 5 in the main BootWare menu to modify the password: The console terminal displays: please input old password:

Please input new password:

Please input new password again:

Password Set Successfully.

NOTE:

The password modification fails when the old password is not correct or new password is inconsistent. Then the system will exit this operation.

Super Password Loss The super password enables you to switch between four super levels. In the event of super password loss, you cannot perform higher level operations.

You can clear the super password by entering 8 in the main BootWare menu.

59

After you clear the super password, quit the menu and reboot the router, you can directly enter system view. The setting is valid for the first reboot of the router only. The super password will be restored after a second reboot.

Backing Up and Restoring BootWare The MSR 20-1X routers do not support backup and restoration of BootWare.

Troubleshooting

Troubleshooting the Power System Symptom:

The PWR LED on the front panel is OFF.

Solution:

Check that:

• The power switch on the router is turned on.

• The switch of the power source is turned on.

• The power cord is correctly connected.

• The output voltage of the power source is compliant with the voltage indicated on the label of the router.

Troubleshooting the Configuration System If the router passes POST after power-on, the startup information of the router will be displayed on the console terminal. If the configuration system is faulty, nothing or illegible characters will be displayed on the console terminal.

Symptom 1:

After the router is powered on, nothing is displayed on the console terminal.

Solution:

1. Check that:

• The power system is normal.

• The console cable is correctly connected.

2. Check the console cable and the terminal (HyperTerminal for example) parameter settings.

Symptom 2:

After the router is powered on, illegible characters are displayed on the console terminal.

Solution:

Verify that the terminal parameter settings are as follows:

Bits per second: 9600

Data bits: 8

Parity: None

Stop bit: 1

Flow control: None

Terminal emulation: VT100

Reconfigure the parameters if their values are different.
