Table 12. 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.
Multiple names are needed if multiple interfaces will be configured.
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.
A single physical port can facilitate multiple interfaces.

Physical port description
An identification string from 1 to 79 characters (alpha and/or numeric) by which the physical port will
be recognized by the system.
Multiple descriptions are needed if multiple ports will be used.
Physical ports are configured within the source context and are used to bind logical Gn interfaces.

Multiple descriptions are needed if multiple ports will be used.
Physical ports are configured within the source context and are used to bind logical Gn interfaces.
Gateway IP address
Used when configuring static routes from the Gn interface(s) to a specific network.
GGSN service Configuration
GGSN service name
An identification string from 1 to 63 characters (alpha and/or numeric) by which the GGSN service
will be recognized by the system.
Multiple names are needed if multiple GGSN services will be used.
will be recognized by the system.
Multiple names are needed if multiple GGSN services will be used.
Accounting context
The name of the context configured on the system in which the processing of GTPP accounting
records is performed.
The context name is an identification string from 1 to 79 characters (alpha and/or numeric).
By default, the system attempts to use the same context as the one in which the GGSN service is
configured.
