Description (partial)

Symptom:
LDI collisions noticed on linecard. This can cause traffic drop for specific ports ( usually the ports which are mapped to the first asic instance). If you have FEXs connected to these ports then FEX can go offline during sup switchover.

Conditions:
sup switchover on n77k chassis with f3 modules and broken out ports.
breakout and no breakout of a port is required to trigger this problem. breakout/no breakout can be done for any port in the chassis to trigger this problem and not necessarily for the ports where traffic drop is seen.
