Solution

The cause is due to an internal transient issue detected in the XMCHIP Packet Table processing.  A single occurrence of this message indicates just a one-time condition.

 

Please perform following to recover the FPC.

  1. Reboot the FPC 1 in an MW.

request chassis fpc slot 1 restart

Restarting the FPC should clear the alarm, if the restart does not help clear the alarm, - Reseat the FPC in MW, if the issue is still seen, reach out to JTAC for further troubleshooting.
