of the GGSN9811.

l When the LMT and the GGSN9811 are connected through a router, the IP addresses can

be in different network segments.

Procedure

Step 1 Choose start> Settings> Control Panelon the computer where the LMT is installed. Then,select Network Connections.

Step 2 Select the local connection of the LMT of which the IP address is to reset. Then, right-click andchoose Properties. The Local Area Connection Propertiesdialog box is displayed. Refer to

2.8 Running MML Commands

This part describes how to run the man-machine language (MML) commands. The local

maintenance terminal (LMT) of the GGSN9811 provides a man-machine interface based on the

MML command line. You can configure data for the GGSN9811 through visual and simple

graphic user interfaces (GUIs) to guarantee the normal running of the system.

2.8.1 Introduction to MML Commands

Man-machine language (MML) commands are an operational means provided by the localmaintenance terminal (LMT) in addition to the graphic user interface (GUI). The GGSN9811

provides abundant MML commands, with which you can perform overall operation and

maintenance to the system.

2.8.2 Introduction to the MML Command Operation Interface

The man-machine language (MML) command window of the local maintenance terminal (LMT)

consists of the menu, toolbar, status bar, and MML command area. The MML command area is

further divided into the following: the command navigation tree pane, the command display

area, the common maintenance/operation record/help information area, and the command and

parameter input area.

2.8.3 Starting the MML Command Line

This part describes how to start the man-machine language (MML) command line when thecurrent window is not the window of the MML command line. Before running the MML

command, start the GGSN9811 MML command line. When the local maintenance terminal

(LMT) is started, the MML command line is started by default.

command line. This can facilitate routine configuration and maintenance.

2.8.5 Batching MML Commands

This part describes how to batch the man-machine language (MML) commands. Batching MML

commands refer to that multiple MML commands are executed at one time. You can run the

edited batch files on the local maintenance terminal (LMT), eliminating the need to run an MMLcommand at one time.

The syntax structure of an MML command is divided into three parts: the command keyword,

parameter, and parameter value. For example:

ADD IP: INTFN="ethernet1/0/0", IPADDR="10.10.10.1", MASK="255.255.255.0";

Here, the character string ADD IPbefore ":" is the keyword of the command; INTFN,

IPADDR, and MASKbefore "=" are parameters, which are separated by ","; ethernet1/0/0,

10.10.10.1, and 255.255.255.0behind "=" are parameter values. The whole command ends with

";".

2.8.2 Introduction to the MML Command Operation Interface

The man-machine language (MML) command window of the local maintenance terminal (LMT)

consists of the menu, toolbar, status bar, and MML command area. The MML command area is

further divided into the following: the command navigation tree pane, the command display
