This command tests each of the four unshielded twisted-pair (UTP) cables. When the test completes, the
command prompts you to enter the show port
portlist
cable diagnostics command to see the results
of the test.
By reviewing the output of the
show
command you can determine:
•
The length of the cable
•
Whether there is a successful termination, or whether there is an open or short
Examples
The following example tests the Ethernet cable inserted into port 1. The four copper pairs do not all
have the same length, which might indicate a kink in the cable, or a open connection:

show port <port list> cable diagnostics
Summit400-48t:28 # show port 1 cable diagnostics
