Gy Interface Support
▀ Features and Terminology
▄ Cisco ASR 5x00 Packet Data Network Gateway Administration Guide
354
In case of terminate and retry-and-terminate, the MIP session is terminated and a CCR-T is sent to the diameter
server.
Result Code Behavior
DIAMETER_RATING_FAILED: On reception of this code, Gy discards all traffic for that category and does
not request any more quota from the server. This is supported at the MSCC level and not at the command level.
DIAMETER_END_USER_SERVICE_DENIED: On reception of this code, Gy temporarily blacklists the
category and further traffic results in requesting new quota from the server. This is supported at the MSCC
level and not at the command level.
DIAMETER_CREDIT_LIMIT_REACHED: On reception of this code, Gy discards all traffic for that category
and waits for a configured time, after which if there is traffic for the same category requests quota from the
server. This is supported at the MSCC level and not at the command level.
DIAMETER_CREDIT_CONTROL_NOT_APPLICABLE: On reception of this code, Gy allows the session to
establish, but without quota management. This is supported only at the command level and not at the MSCC
level.
DIAMETER_USER_UNKNOWN: On reception of this code, DCCA does not allow the credit control session to
get established, the session is terminated. This result code is supported only at the command level and not at
the MSCC level.
For all other permanent/transient failures, Gy action is dependent on the CCFH setting.
