Hi Experts,
What would be best practice when shutting down ports.
I will do next: Create an svi vlan 100 and shut it down(bin bucket vlan), Identify ports not in use then shut them down and put them on vlan 100.
My question is if there is a way that when I need one of these shut down ports to identify the port that is down? I know I can tone the port but is there an easier way to do it?

Please advise

If the port is unused would it not normally be empty?
Good practice is to remove all unnecessary patches so when you need a port you patch it in and configure it.
If there's still things patched and you still want to leave them in but shut the port down perhaps using the description field for the device / end termination port might make it easier to find them should you wish to re-activate the port?

Hi There,

Some points of argument:

This would not be needed.

You need to verify there are packets/traffic on the port.

My advice:

i)
Set up cacti (free monitoring tool) to identify the unused ports in your network.
ii)
Once identified, ensure that the physical patching on the port is kept free end to end ( Switch to the patch panel).
It becomes convenient to identify the unused ports during future purposes.
iii)
Maintain an inventory at a shared location that has number of free ports count for each switch.
As and when ports are being used/freed,  update the sheet.
