Error frames (for example, CRC errors) on a port

Symptom

The output from the display interface command shows that error frames exist (for example,
CRC error frames) on a port.

Solution

To resolve the issue:
1. Examine the error frame statistics and identify the error frame type:
a. (Optional.) Use the reset counter interface command in user view to clear the packet
statistics of the port.
This command resets the values of each statistical field to 0, so that you can view the
statistics changes more clearly.
b. Use the display interface command to display the incoming packet statistics and
outgoing packet statistics of the port.
c. Determine the type of error frames that are accumulating.
2. If the port is a fiber port, verify that the optical power of the transceiver module is operating
correctly:
Replace it with a transceiver
