Description
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 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.
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 DHCP interface and be bound to the DHCP service.
Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
Used when configuring static routes from the DHCP interface(s) to a specific network.
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.
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 DHCP interfaces.
This is an identification string between 1 and 63 characters (alpha and/or numeric) by which the DHCP
service will be recognized by the system.
Multiple names are needed if multiple GGSN services will be used.
The IP address of each DHCP server that the system is to communicate with must be configured
.Multiple servers can be configured. If multiple servers are configured, each can be assigned a priority
from 1 to 1000. The default priority is 1.
