Configuring GTPP for SGSN
This section provides the GTPP configuration for SGSN.
1. At the local context level, configure the system to reserve a CPU for performing a AAA proxy function for
accounting.
configure
context local
gtpp single-source private-extensions
end
2. When gprs-service and sgsn-service are configured in source context, configure the GTPP group related
parameters like GTPP server parameters, GTPP dictionary, and optionally CGF to support GTPP accounting:
configure
context source
gtpp group default
gtpp charging-agent address 192.168.10.10
gtpp server 192.168.10.2 priority 1 max 1
gtpp dictionary custom10
end
Important:
The above configuration is applicable for the transfer of generated CDRs to the
CGF server over GTPP protocol. Configuration varies slightly if GSS/HDD is used for
transferring/storing CDRs.
