diagShow

Figure B-52 shows the diagShow command which summarizes the

diagnostics results run since the Switch was last booted, including POST

results. The fields are described in Table B-15.

NOTE:

This command shows an FL_Port as being offline if you are running cross port

connected testing, the reason is that you can have only one Principle per Switch. The

FL_Port to FL_Port testing still proceeds even though this is NOT the correct way to

connect FL_Ports.

The command also allows you to loop on the command. For example,

diagShow 4 executes diagShow every 4 seconds continuously unless stopped

by pressing Return. This may be used to isolate a bad GBIC. A port with a

changing LLI_errs value is prefixed by "**" in the display. The example

below shows 2 passes, the first pass without an error on the line st11 (in bold)

and the second pass shows an error on the line st11 (in bold). The screen

shows:

■

Each port number diagnostic status (OK/BAD) and port state (up

(online)/down (offline))

■

Frames transmitted (frTx) frames received (frRx) and Low Level

Interface error count (LLI_errs) for active ports

■

Central memory status (OK/FAULTY)

■

Total diagnostics frames transmitted (Tx) and received (Rx) since boot,

which are normally the same, but may differ because of failure modes.

NOTE: Port 16 is the embedded port.
