Description
The GGSN can be configured treat communications from unconfigured SGSNs in one of the following
ways:
Treat the SGSN as if it is on a foreign PLMN
Treat the SGSN as if it is on a home PLMN
Reject communications from unconfigured SGSNs (default)
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 Ga interface.
Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
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 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
