HWPORTMAN-4
Error Message C4K_HWPORTMAN-4-BLOCKEDTXQUEUE:Blocked transmit queue HwTxQId[dec] on
[char], count=[dec]
Explanation
A transmit queue on a port is blocked for reasons other than “paused.” Bad hardware
could cause this problem.
Recommended Action Contact your technical support representative.
Error Message C4K_HWPORTMAN-4-CHECKFORDUPLEXMISMATCHANDPAUSE: [char] Tx-Queue could
be blocked due to duplex mismatch or receiving excessive pause frames
Explanation
Please use the show interface <name> count all command to verify the excessive
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.
Recommended Action If this message is seen when the duplex settings are correct, contact your
technical support representative.
Error Message C4K_HWPORTMAN-4-GIGAPORTRESETBYRXCONFIGWORD:[char] has been reset by
the received autonegotiation word.
Explanation The port stayed connected during switchover, but the device on the other end of the link
lost synchronization and restarted autonegotiation.
Recommended Action This is an informational message only. No action is required.
