5. Verify that the port is operating correctly:
{ If the port is a copper port, connect the port directly to a PC.
{ If the port is a fiber port, replace the transceiver module in the port.
If the port can receive packets, troubleshoot the remaining possible points of failure on the
transmission path. The troubleshooting process is beyond the scope of this document.
6. Determine whether the port has received a large amount of flow control frames:
a. Use the display interface command to view the number of pause frames.
If the number of pause frames is accumulating, you can determine that the port has sent or
received a large amount of flow control frames.
b. Verify that the incoming traffic and outgoing traffic have not exceeded the maximum traffic
processing capability of the local device and the peer device.
7. If the problem persists, contact HP Support.
