Monitoring and Managing the Switch

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.

• 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.

• 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.

• Discarded Frames

The number of Class 3 frames discarded, including multicast

frames with bad D_IDs.
