IFL address add failure on the FPC

  • 1.  IFL address add failure on the FPC

    Hi All,

    We have recently swapped out an FPC1(MPC3E NG HQoS) with an RMA part and after 4 days, we noticed slowness/latency, unable to access the device remotely. We got into the adjacent router from where we got to access the router on the loopback IP address and noticed only the errors on the FPC1 but nothing abnormal.

    Feb 12 13:49:08  LTZ-PE1-RAH fpc1 IFRT: 'IFL address add' (opcode 29) failed 
    Feb 12 13:49:08  LTZ-PE1-RAH fpc1   ifl 430813936; local addr attach error (15) 
    Feb 12 13:49:08  LTZ-PE1-RAH fpc1 IFRT: 'IFL address add' (opcode 29) failed 
    Feb 12 13:49:08  LTZ-PE1-RAH fpc1   ifl 430813936; local addr attach error (15)

    We attempted to reboot this FPC alone after which the issue got resolved and traffic is all working fine. However, the above errors continue to log on the FPC.

    Not sure if these are the reason for the traffic impact observed but since these are still being logged. Could not find much info on these logs. Appreciate your help on the possible impact of these events.

    Thanks and Regards,
