Interface Port Monitoring FrameErrors (9020)

Field

Description

Invalid CRCs

Count of frames received with invalid CRC. This count is part of the Link Error Status Block (LESB). (FC-PH 29.8). Loop ports should not count CRC errors passing through when monitoring. Note, this is a Fibre Channel only statistic.

Class 3 Discards

Count of Class 3 Frames that were discarded upon reception at this port. There is no FBSY or FRJT generated for Class 3 Frames. They are simply discarded if they cannot be delivered. Note, this is a Fibre Channel only statistic.

FBSY Frames

Count of times that FBSY was returned to this port as a result of a frame that could not be delivered to the other end of the link. This occurs if either the Fabric or the destination port is temporarily busy. Port can only occur on SOFc1 frames (the frames that establish a connection). Note, this is a Fibre Channel only stat. This is the sum of all classes. If you cannot keep the by class counters, then keep the sum counters.

FRJT Frames

Count of times that FRJT was returned to this port as a result of a Frame that was rejected by the fabric. Note, this is the total for all classes and is a Fibre Channel only statistic.
