CSCul85477 - PGW not setting the T flag & changing the E2EID on Gx
retransmission
Applicable Products: eHRPD, GGSN, P-GW
Feature Changes
Configuration Support for Setting T bit and Sending Same E2E on Retransmissions
When one of the PCRF servers is down, and if failure-handling is set to “retry-and-terminate” the CCR messages from
gateway is retried to the secondary PCRF. As per RFC 3588, the T bit must be set for retried messages so that the PCRF
can identify duplicate messages. The End-to-End Identifier (E2E ID) has to remain the same. This feature is applicable
to Gy and Rf messages as well.

Previous Behavior: When Diameter message is retried, the T bit was not set in the message as well as a different End-
to-End Identifier (E2E ID) is sent in the retried message.

New Behavior: New CLI configuration options are introduced to set T-bit in a retried message along with having same
End-to-End ID. Similar CLI command for setting T-bit is present under Credit Control Group configuration mode,
which when configured will take effect for Gy messages else endpoint configuration will be used.
