Invalid Cyclic Redundancy
Checks (CRC)
Errors have been detected in the Fibre Channel frame. Invalid CRC messages occur
when the number of CRC errors in Fibre Channel frames for specific source ID (S_ID)
and destination ID (D_ID) pairs change. These messages can also be caused by dirty
or aging equipment and temperature fluctuations.
Receive Performance The percentage of word frames traveling from the configured S_ID to the D_ID exceeds
the configured thresholds.
Transmit Performance The percentage of word frames traveling from the configured D_ID to the S_ID; user
configuration triggers these messages, so you can use the Transmit Performance area
to tune your network.
