Command reference
FBusy
Number of times the switch sent a fabric busy (F_BSY) frame because
the Class 2 frame could not be delivered within ED_TOV time; or the
number of class 2 and class 3 F_BSY frames generated by this port in
response to incoming frames. This usually indicates a busy condition on
the fabric or N_Port that is preventing delivery of this frame.
Flowerrors
Number of frames received there were no available credits
FReject
Number of frames from devices that were rejected
InvalidCRC
Invalid CRC detected
InvalidDestAddr
Invalid destination address detected
IOStreamGuard
I/O StreamGuard status
LinkFailures
Number of optical link failures detected by this port. A link failure is a
loss of synchronization or a loss of signal while online. 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.
LinkSpeed
Port transmission speed
LinkState
Port activity status
LIP_AL_PD_ALPS
Number of F7, Arbitrated Loop Source Address (AL_PS) Loop
Initialization Primitives (LIPs), or Arbitrated Loop Destination Address
(AL_PD) (vendor specific) resets performed
LIP_F7_AL_PS
Number of LIP frames that reinitialized the loop. An L_Port, identified by
AL_PS, may have noticed a performance degradation and is trying to
restore the loop.
LIP_F8_AL_PS
Number of LIP frames indicating a loop failure detected by the L_Port
identified by AL_PS
LIP_F7_F7
Number of LIP frames that acquire a valid Arbitrated Loop Physical
Address (AL_PA)
LIP_F8_F7
Number of LIP frames indicating that a loop failure has been detected
at the receiver
Login
Number of device logins that have occurred on the port
LoginStatus
Device login status for the port:
LoggedIn
or
NotLoggedIn
Logout
Number of device logouts that have occurred on the port
LongFramesIn
Number of incidents when one or more frames that are greater than the
maximum size were received
LoopTimeouts
A two second timeout, as specified by FC-AL-2
LossOfSync
Number of synchronization losses (>100 ms) detected by this port. A
loss of synchronization is detected by the receipt of an invalid
transmission word.
LostFrames
Number of incidents of lost frames
LostRRDYs
Number of incidents of lost Receiver_Ready (R_RDY) primitives
MaxCredit
Maximum number of port buffer credits
MediaSpeeds
Possible transmission speeds for the port
