Destination Context Configuration

The following table lists the information that is required to configure the destination context.
▄ Cisco ASR 5000 Series Gateway GPRS Support Node Administration Guide
Description
An identification string between 1 and 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 Ga interfaces.
Used when configuring static routes from the Ga interface(s) to a specific network.
The IP address of the system‟s GGSN interface.
IP address:The IP address of the CGF server to which the GGSN will send accounting information.
Multiple CGFs can be configured.
Priority:If more than on CGF is configured, this is the server‟s priority. It is used to determine the
rotation order of the CGFs when sending accounting information.
The priority can be configured to any integer value from 1 to 1000. The default is 1.
Maximum number of messages:The maximum number of outstanding or unacknowledged GTPP
messages allowed for the CGF.
The maximum number can be configured to any integer value from 1 to 256. The default is 256.
The following optional fields can be specified/configured in CDRs generated by the GGSN:
diagnostics
duration-ms (the time specified in the mandatory Duration field is reported in milliseconds)
local-record-sequence-number
plmn-id
IP address:The static IP address of the mobile station‟s for which network-requested PDP context
activation will be supported.
Up to 1000 addresses can be configured.
Destination context name:The name of the destination context configured on the system that contains
the IP address pool containing the mobile station‟s static address.
International Mobile Subscriber Identity (IMSI): The IMSI of the mobile station.
APN: The name of the access point that will be passed to the SGSN by the GGSN for the mobile
station.
Communications with the HLR from the GGSN go through a GSN-map node that performs the
protocol conversion from GTPC to SS7.
The IP address of the map node must be configured. Only one GSN-map node can be configured per
source context.
