Description
An identification string from 1 to 79 characters (alpha and/or numeric) by which the source context
will be recognized by the system.
NOTE: The name of the source context should be the same as the name of the context in which the
FA-context is configured if a separate system is being used to provide GGSN/FA functionality.
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.
These will be assigned to the Gn 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 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.
Used when configuring static routes from the Gn interface(s) to a specific network.
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.
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.
The port used by the GGSN service and the SGSN for communicating GTPC sockets for GTPv1.
The UDP port number and can be any integer value from 1 to 65535. The default value is 2123.
Mobile Country Code (MCC): The MCC can be configured to any integer value from 0 to 999.
Mobile Network Code (MNC): The MNC can be configured to any integer value from 0 to 999.
The GGSN can be configured with information about the SGSN(s) that it is to communicate with.
This includes the SGSN‟s IP address and subnet mask and whether or not the SGSN is on a foreign
PLMN.Multiple SGSNs can be configured.
