Description
Number of E_Port logins.
Number of class 2 and class 3 fabric busy (F_BSY) frames generated
by this port in response to incoming frames. This value usually
indicates a busy condition on the fabric or N_port that is
preventing delivery of this frame.
Number of times a frame is received and all the switch ports
receive buffers are full. The normal Fabric Login exchange of
flow control credit should prevent this from occurring. The
frame will be discarded.
Number of frames, from devices, that have been rejected. Frames
can be rejected for any of a large number of reasons.
Number of invalid Cyclic Redundancy Check (CRC) frames
detected.
Number of address identifier (S_ID, D_ID) errors. AL_PA equals
non-zero AL_PA found on F_Port.
Number of optical link failures detected by this port. A link failure
is a loss of synchronization or loss of signal while not in the
offline state. A loss of signal causes the switch to attempt to
re-establish the link. If the link is not re-established, a link failure
is counted. A link reset is performed after a link failure.
Number of F7, AL_PS LIPs, or AL_PD (vendor specific) resets
performed.
This LIP reinitializes the loop. An L_port, identified by AL_PS,
may have noticed a performance degradation and is trying to
restore the loop.
A loop initialization primitive frame that acquires an AL_PA.
This LIP denotes a loop failure detected by the L_port identified
by AL_PS.
A loop initialization primitive frame used to indicate that a Loop
Failure has been detected at its receiver and does not have a
valid AL_PA.
Number of device logins that have occurred on the switch.
Number of device logouts that have occurred on the switch.
Number of incidents in which one or more frames greater than
the maximum size (2,136 bytes) are received
Number of loop timeouts.
Number of synchronization losses (>100 ms) detected by this
port. A loss of synchronization is detected by receipt of an
invalid transmission word.
Number of loop timeouts.
Number of bad primitives received by the port.
