Edge Switch 2/24 Product Manager User Guide
Received Frames
The number of Class 2 frames received by this F_Port from its attached
N_Port.
Transmitted Frames
The number of Class 2 frames transmitted by this port to its attached port.
Busied Frames
The number of F_BSY frames generated by this F_Port against Class 2
frames. This can occur if frames are received before the switch completes
initialization or if the switch is servicing so many requests that it can not
process a new request. The port generates frames if the switch is not ready to
accept commands. This may indicate temporary congestion.
Rejected Frames
The number of F_RJT frames generated by this F_Port against Class 2 frames.
These frames usually occur because of attached device errors. The device is
expected to correct the error based on the reject code, then retry its request. If
the device is able to recover, there is no cause for concern. If not, further
troubleshooting may be necessary. There are no thresholds for this value.
Typically, this occurs because the destination is not available due to the
device's action.
