Description (partial)

Symptom:
In an  INTRA-box redundancy configuration, the STANDBY FP and ACTIVE FP may not be syncing dplane HA records robustly.

The easiest  way for the customer to recognize if this *might* be  happening is by examining the output  of the
show platform hardware qfp active system intra and the show platform hardware qfp standby  system intra CLIs.

If the output shows the counters  " rx dropped" and/or  "retx" continuously  incrementing, then this problem may have been encountered.

Conditions:
DUAL FP systems with stateful HA features such as NAT configured.
