Show interface link Catalyst 4500, 6500, 3750, 2960

The "show interfaces link" command is supported in Catalyst 4500 Series only, this command displays how long a cable has been disconnected from an interface and you can add the modifier known like “include” with the keyword “weeks” #sh int link | inc week, you will have more ports released for future connection..

As we know this command is not supported in Catalyst 6500 series, 3750 series and 2960 series but you can use the "sh int | i ther|rial|link|Vlan|ast input" and "sh int gi 0/1 | inc ast input" command that will display the down time for each port instead. Here are an example:

Show interface link 6500, 3750, 2960
CN-CSW-A01#sh int | i ther|rial|link|Vlan|ast input

  Last input 1d01h, output 1d01h, output hang never
CN-ASW-B02# sh int gi 0/8 | inc ast input
  Last input 00:00:35, output 00:00:04, output hang never

You could now do a show show interface link to see the the down time for each port, a port was last used and plan for future connection.
