Description (partial)

Symptom:
Some Cat6K line cards/ supervisors (which has Metropolis Argos) may exhibit intermittent traffic loss on one or few ports.  So far, we have seen the issue with 6904-40G, 6880X-LE, sup2T-10G but this list is not exclusive, 

Traffic loss will be completely silent, with no drop counters increment on any interfaces and no user facing exception/syslog. Shut/No-shut of the interface will not resolve the issue.

Conditions:
Cards that have Metropolis Argos.
