perf [option]
Displays performance information for all ports. See the “Show Perf command” on page 50.
port [port_number]
Displays operational information for the port given by [port_number]. Ports are numbered
beginning with 0. If the port number is omitted, information is displayed for all ports. Table 13
describes the port parameters. For information about port numbering and mapping, see Table 37
on page 127
✏
NOTE
For external ports (0,15), all parameters apply. For internal ports (1 through 14) only
AdminState applies.

Entry Description
AIinit Incremented each time the port begins AL initialization.
AIinitError Number of times the port entered initialization and the initialization failed.
ClassXFramesIn Number of class x frames received by this port.
ClassXFramesOut Number of class x frames sent by this port.
ClassXWordsIn Number of class x words received by this port.
ClassXWordsOut Number of class x words sent by this port.
DecodeError Decoding error detected.
EpConnects Number of times an E_Port connects through ISL negotiation.
FBusy Number of times the switch sent a F_BSY because Class 2 frame could not be
delivered within ED_TOV time. Number of class 2 and class 3 fabric busy
(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 Received a frame when there were no available credits.
FReject Number of frames from devices that were rejected.
InvalidCRC Invalid CRC detected.
InvalidDestAddr Invalid destination address detected.
LIP ALPD ALPS Number of F7, AL_PS LIPs, or AL_PD (vendor specific) resets, performed.
LIPF7ALPS This LIP is used to reinitialize the loop. An L_port, identified by AL_PS, may
have noticed a performance degradation and is trying to restore the loop.
LIPF8ALPS This LIP denotes a loop failure detected by the L_port identified by AL_PS.
LIPF7F7 A loop initialization primitive frame used to acquire a valid AL_PA.
LIPF8F7 A loop initialization primitive frame used to indicate that a loop failure has been
detected at the receiver.
