could cause this problem.
Contact your technical support representative.
Recommended Action
Please use the show interface <name> count all command to verify the excessive
Explanation
collisions and pause frame counters. Duplex mismatch problems can be fixed by configuring both
ends of a link in auto-negotiate mode. It can also be fixed by turning off auto-negotiation on both
ends of the link and ensuring that the duplex configuration on both ends is the same. Excessive pause
frames are not expected under normal conditions. If they occur, investigate on the other end of the
link to address the problem. After fixing the problem, the port's TxQueue status can be checked by
using the show platform hardware interface <name> tx command. The results will indicate
whether one or more TxQueue's on this port are still stuck or working properly.
If this message is seen when the duplex settings are correct, contact your
