Class 2 Statistics - HP 316095-B21 - StorageWorks Edge Switch 2/24 User Manual

Monitoring and Managing the Switch
• Offline sequences
The number of offline sequence that the port has received or transmitted.
• Link resets
The number of link reset protocol frames received/transmitted by this port from/to
the attached switch. The switch transmits a link reset to initiate the link reset
protocol or recover from a link timeout. The switch receives a link reset from an
attached device if the device wishes to initiate the link reset or recover from a link
timeout.
There are not thresholds for these values. You may determine that a problem exists
by the rate that the value changes.
• LIPS
The number of Loop Initialization Primitives (LIPS) generated/detected by this
port. These cause re-initialization of the port.

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 the 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 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
