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

BAD

state

The current state of the port. Possible values include

(active),

(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

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
