Can BIG-IP iRule do GTP-C (version 2) modification on the QCI (QoS-Class-Identifier-AVP ) parameter ?

Dear All,

     Can BIG-IP do GTP-C (version 2) modification on the QCI parameter ?
     Attached file is Diameter payload message in S11/GTP-C(v2) packets.

     In Diameter payload you can QoS-Class-Identifier-AVP with parameters, can we use iRule to modify the parameter value of QoS-Class-Identifier-AVP ?
     I have full S11/GTP-C(v2) message format, if need I can mail you.
     I have checked Devcentral, looks like iRule can do some GTP process, but not to AVP parameter.

    i think i do not see set operation in gtp:: command. anyway, i understand you can still modify gtp message by using udp:: command.

    Hi Nitass,

     If we can't modify GTP parameter through gtp::command, how can we use udp::command to modify GTP parameter ?
 Can you give us a detail suggestion ?

 Thank.

 Regards,

 Kevin
