Information Required
The following sections describe the minimum amount of information required to configure and make the GGSN
operational on the network. To make the process more efficient, it is recommended that this information be available
prior to configuring the system.
operational on the network. To make the process more efficient, it is recommended that this information be available
prior to configuring the system.
There are additional configuration parameters that are not described in this section. These parameters deal mostly with
fine-tuning the operation of the GGSN in the network. Information on these parameters can be found in the appropriate
sections of the Command Line Reference.

Source Context Configuration
The following table lists the information that is required to configure the source context.
Table 1. Required Information for Source Context Configuration
Required Information
Description
Source context name
An identification string from 1 to 79 characters (alpha and/or numeric) by which the source context
will be recognized by the system.
will be recognized by the system.
Gn Interface Configuration
Gn interface name
An identification string between 1 and 79 characters (alpha and/or numeric) by which the interface
will be recognized by the system.
will be recognized by the system.
Multiple names are needed if multiple interfaces will be configured.
IP address and subnet
These will be assigned to the Gn interface.
Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
Physical port number
The physical port to which the interface will be bound. Ports are identified by the chassis slot number
where the line card resides in, followed by the number of the physical connector on the line card. For
example, port 17/1 identifies connector number 1 on the card in slot 17.
