Table 34. diagShow command field descriptions
Field
Description
Diagnostics status
The title header displays the time the diagShow command was
performed.
port#
The port number.
diags
The current diagnostic status of the port. Possible values include
OK
,
BAD
.
state
The current state of the port. Possible values include
UP
(active),
DN
(inactive).
lm0-7 (8-port)
lm0-15 (16-port)
The frame counts of active ports. The display shows the number
of frames transmitted and received and low level interface counts
(LLI_errs).
Central Memory
The central memory status. Possible values include
OK
,
FAULTY
.
Total diag frames Tx
The total diagnostics frames transmitted (Tx) since the last
startup. This number usually corresponds to the total frames
received (Rx) but may differ because of failure modes.
Total Diag Frames Rx
The total diagnostics frames received (Rx) since the last startup.
This number usually corresponds to the total frames transmitted
(Tx) but may differ because of failure modes.
portLoopbackTest
Figure 55 on page 109 shows the portLoopbackTest command, which verifies the
intended functional operation of the switch by sending frames from the transmitter
