Determine length of cables

[Sara_B]

Hello,

Is there comand line in HP  J9091A that shows the length of cables (UTP or Fiber) connected to its ports ?

Hello ,

Looks like you wanted to check cable lengh of device Aruba 8212 , as per below document you can test the length only on 1G copper ports . 

switch# test cable-diagnostics <ports>
This command will cause a loss of link on all tested ports and will take
several seconds per port to complete. Use the ‘show cable-diagnostics’ command to view the results.

Continue (y/n)? y
switch# show cable-diagnostics <ports>
