› When we say “ Native Ethernet “ , we mean that source of traffic is

Packets like in data network and there is no conversion between PDH

and Ethernet

› Microwave links should be hybrid links to configure native Ethernet

› Hybrid Microwave handles packets and TDM natively (without mapping

onto another protocol), transporting multimedia traffic efficiently and

allowing operators to launch data services cost-effectively without

impacting traditional TDM services.

Native Ethernet


Requirements to interface with Ericsson nodes

› LCT software was installed on your laptop as user interface

( You should use latest release )

› Physical cable for connection

( LAN or Mini-USB cable )

› Authorized Account for Access

How to configure Native Ethernet on Ericsson AMM

Ethernet Configuration can be created using one of following

connections :

1- Layer 1 connection

• It connects WAN and LAN interfaces through Layer 1

• It don’t use Ethernet switch ports for connections

• There is no VLAN creation

• It transmits any packet regardless its VLAN ID




• It use Ethernet switch ports for connections of WAN and LAN interfaces

• There is a VLAN creation

• We connect WAN and LAN interfaces via VLANs

• We can control transmission of packets according to its VLAN



› We will focus on Ethernet configuration using Layer 2 connection

› Layer 2 Connection procedures :

1. Check on packet link capacity in radio link configuration

2. Create new WAN interface for packet link

3. Configure switch mode for Ethernet switch

4. Assign switch port for each LAN or WAN port

5. Configure port role for all assigned switch ports

6. Finally , Create new VLAN then add assigned switch ports

7. Review your configurations using overview windows of Ethernet


How to configure Native Ethernet on Ericsson AMM Procedure # 1 :

› To start your configurations , you should check that there are a packet

link capacity ≥ 2Mb/s on MW link configuration



› Create WAN for available packet link capacity using one from RL-IMEs

existing in NPU slot

› Drag and drop packet link from available packet links box to assigned

packet links box



› After saving last configuration , WAN is created and displayed in WAN

interfaces in drop menu of Ethernet in management tree



› Following tables show Capacities of RL-IMEs for different types NPU

cards

RL-IME Number Number of RL-IMEs

Number of Packet Links

per RL-IME

RL-IME Capacity

100 1 4 1.6 Gbps

101 1 2 830 Mbps

102 – 104 3 1 500 Mbps

RL-IME Number Number of RL-IMEs Number of Packet Links

per RL-IME

RL-IME Capacity

100 – 101 2 4 1.6 Gbps

102 – 103 2 4 830 Mbps

104 – 107 4 2 830 Mbps

108 – 119 12 1 500 Mbps



› Configure switch mode for Ethernet switch to be “ Customer mode

(802.1Q) “ .



› Assign switch port number to LAN and WAN ports which need to be

connected via VLAN then switch their Admin Status to be “ Up “



› Configure port role for each switch port was assigned to WAN or LAN

› For WAN interface , port role will be “ I-NNI “



› For LAN interface , port role will be “ UNI “



› Create New VLAN which has planned VLAN ID number and VLAN

name

› Add switch ports which assigned and configured for LAN and WAN

ports to Ports/member field

› Configure Unregistered Multicast to be “ Filter “

› Don’t modify or add any port to Default VLAN


How to configure Native Ethernet on Ericsson AMM Tagged and Untagged LAN ports

› LAN port can be configured to be tagged or untagged port according to

customer request

› If LAN port will be untagged port

1. Check on configurations of switch port assigned to this LAN port

2. Add switch port to Ports / Untagged in VLAN configurations


How to configure Native Ethernet on Ericsson AMM Tagged and Untagged LAN ports

› If LAN port will be tagged port

– Simply don’t add its switch port to Ports/Untagged



› Review your configurations using overview windows of Ethernet and

VLAN


How to configure Native Ethernet on Ericsson CN210

› Ericsson CN210 supports only one MW link on its indoor equipment

› So it has only one WAN interface and it don’t need to be created as in

case of TN using RL-IME

› You can complete Ethernet configurations starting from configure

Ethernet switch ( Procedure # 3)


Expected problems appear after configuration

1- WAN operational status is down :

• Check on Admin status of WAN , it should be up

• Check on packet link capacity , it should be ≥ 2Mbit/s

• MW link should be up (i.e. Near End site and Far End site are connected )

• WAN interface in other site was created

• Packet link capacities must be matched in both sites of MW link



2- LAN operational Status is down :

• Check on Admin status of LAN , it should be up

• Check on physical connection between two LAN ports ( LAN cable has 2 RJ-45

connectors) and two connectors should be installed as straight or crossover

standards

• If LAN still down you can change speed of this port from “ Auto “ to “ Full duplex 1000

Mbit/s “ and check again on status



3- WAN or LAN ports can’t transmit or receive packets :

• Check on status of all ports participate in connection from source ( RNC ) to

destination ( Node B ) . If there is disconnected port in path , other ports will have

this problem

• Review your configurations on all nodes participate in this connection VLAN ID and Name should be matched in all nodes for this VLAN

VLAN in each node should include all switch ports assigned to WAN and LAN planned for this connection

Each switch port configured with right port role according to its connectivity ( WAN or LAN )

Admin Status and operational status of all ports are “ UP “


MINI-LINK Craft Wizards

› You can use Mini-link craft wizards to perform a basic configurations

› It is used to create



› It helps user to avoid any missing step in his configurations

› It generates a summary in final window to review your work

› You can get it by press on Wizards tab in main tool bar of Mini-link

craft



› After select Layer 2 Connection Wizard from Wizards menu ,

Welcome page will open to start Ethernet configuration

› It will inform you about available configurations



› Press Next to open Task Selection page , Then read and follow

instructions of window



› Step #1 help you to configure both LAN and WAN ports

› Select Native Ethernet WAN interface to configure radio link packet link



› Press Next to open Configure Native Ethernet WAN interface page

› It displays existing WAN interfaces for any modifications



› Select Create New WAN interface then press next



› Next page Configure Traffic Capacity is used for select RL-IME for

packet link capacity



› After Selecting RL-IME , Add radio link packet link capacity



› Next page shows Dimension Ethernet Capacity

› You can change Ethernet capacity according to total link capacity

› Total link capacity = PDH capacity + Ethernet capacity



› Next page is summary for previous configurations



› Press Finish to execute your configurations on WAN interface



› Press on “ Go To Task Selection Page “ icon to go back to this page

› Now Select LAN interface from Step 1



› Press Next to display available LAN ports for selection

› Select assigned LAN port for Ethernet connection



› Next Page shows drop menu of LAN port speed

› Leave its speed on default “ Auto “



› Next page is summary of LAN port configuration



› Press Finish to execute your configurations on LAN interface



› Press on “ Go To Task Selection Page “ icon to go back to this page

› Select Customer mode and press Next



› Next page displays existing VLANs for any modifications

› Select Create new Layer 2 Connection

› Add VLAN ID , Name to new VLAN



› Next page shows all WAN and LAN interfaces in node

› Add assigned WAN and LAN interfaces for this connection to new

VLAN



› Assign switch port for each inserted interface

› Modify Port role for inserted interfaces

› “I-NNI” for WAN interface and “ UNI “ for LAN interface



› Next three pages don’t need to be modified , leave it with default

configurations ( Bandwidth profiles , QOS and L2 control protocols )

› Summary page for review your configurations before finishing
