gtpp single-source
Configures the system to reserve a CPU for performing a proxy function for accounting.
Product
GGSN, SGSN, P-GW
Privilege
Security Administrator, Administrator
Syntax
Defines the LRSN generation at proxy. The AAA proxy will generate the LRSN for all CDR types generated
by either the GGSN or the SGSN.
Default: disabled
by either the GGSN or the SGSN.
Default: disabled
It is an optional keyword, enables the proprietary use of customer-specific GTPP extensions.
If
If
is not configured, all customer specific private extensions related to GTPP
message transfer with CGF and recovery through GSS are disabled.
Important:
In order for the customer-specific extensions to work properly, the
command in the Context Configuration Mode should be set to 65400 and the
command‘s
value
should be set to ―1‖.
Disables GTPP single-sourcing. This is the default setting.
Caution:
Entering this command while PDP contexts are in process could cause the loss of pending CDRs. The
configuration must be saved and the chassis reloaded for this option to take effect.
Usage
When GTPP single-sourcing is enabled, the system‘s AAA proxy function generates requests to the
accounting server using a single UDP source port number, instead of having each AAA Manager generate
independent requests with unique UDP source port numbers. This is accomplished by the AAA Managers
forwarding their GTPP PDUs to the AAA Proxy function that runs on a reserved PSC/PSC2 CPU. Since a
PSC/PSC2 CPU is being reserved, fewer Session Managers and AAA Managers will be started on that PSC.

Caution:
This command must be entered prior to the configuration of other services. Specifying it later may
return an error due to a lack of CPU availability.
