Description (partial)

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.

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.
