Description
Selects the accounting protocol. GTPP or RADIUS are supported. In addition, accounting can be
completely disabled. The default is to perform accounting using GTPP.
NOTE: The examples discussed in this chapter assumes GTPP is used.
Specifies how the system handles authentication: using a protocol (such as CHAP, PAP, or
MSCHAP), or not requiring any authentication.
Specifies whether or not the GGSN accepts the CC from the SGSN for home, visiting, and roaming
subscribers.
By default the GGSN accepts the CC from the SGSN for all three scenarios.
If the GGSN is to use its own CC for any of these scenarios, then each scenario requires the
specification of behavior bits and a profile index to use.
NOTE: The profile index parameters are configured as part of the GGSN service.
If DNS will be used for the APN, IP addresses can be configured for primary and secondary DNS
servers.
The name of the system destination context to use for subscribers accessing the APN. If no name is
specified, the system automatically uses the system context in which the APN is configured.
The maximum number of PDP contexts that are supported for the APN.
The maximum number can be configured to any integer value from 1 to 1500000. The default is
1000000.
The type of PDP contexts supported by the APN. The type can be IPv4, IPv6, both IPv4 and IPv6, or
PPP. IPv4 support is enabled by default.
The level of verification that will be used to ensure a MS‟s subscription to use the APN. The GGSN
uses any of the following methods:
No verification and MS supplies APN
No verification and SGSN supplies APN
Verified by SGSN (default)
Home Agent IP Address: The IP address of an HA with which the system will tunnel subscriber
Mobile IP sessions.
Configuring this information tunnels all subscriber Mobile IP PDP contexts facilitated by the APN to
the same HA unless an individual subscriber profile provides an alternate HA address.
Parameters stored in individual profiles supersede parameters provided by the APN.
Mobile IP Requirement: The APN can be configured to require Mobile IP for all sessions it
facilitates. Incoming PDP contexts that do/can not use Mobile IP are dropped.
This is an identification string from 1 to 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.
These will be assigned to the AAA interface.
Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
