Class 2 Statistics
The Class 2 Statistics table includes:
•
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 F_Port
to its attached N_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 cannot 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.
•
Four Byte Words Received—The number of four-byte words received.
•
Four Byte Words Transmitted—The number of four-byte words transmitted.
Class 3 Statistics
The Class 3 Statistics table includes:
•
Received Frames—The number of Class 3 frames received by this F_Port from
its attached N_Port.
•
Transmitted Frames—The number of Class 3 frames transmitted by this F_Port
to its attached N_Port.
•
Discarded Frames—The number of Class 3 frames discarded, including
multicast frames with bad D_IDs. The director increments this count when it
discards a frame that cannot be routed. This occurs most frequently when a
destination becomes unavailable without the source realizing the destination is
unavailable. There are no thresholds for this value. Typically, this occurs when the
destination is not available due to the destination device's action.
•
Four Byte Words Received—The number of four-byte words received.
•
Four Byte Words Transmitted—The number of four-byte words transmitted.
