Command to determine if Switch is PoE?

sh power inline?

So if I get an output that indicates the following means that each port is available to provide 15.4 Watts?

370 watts is usually the Sign of a pOE switch, but the best way to find out is to do a show inventory. It will give you the part number of your switch which you can look up on cisco's website to determine if its POE. I have ton's of customers who buy switches on there own without talking to us who buy none POE switches then call us when they can't power there phones.

If you get a list of commands, you most likely have a PoE switch.

You should see % Unrecognized command if the switch cannot provide inline power.

Results may vary with model and IOS version, although if you see the % Unrecognized command reply, you almost certainly do NOT have a PoE model.

I don't think that the "show power inline" command will even work on a non PoE switch.

The command works on my 3550 non-PoE

Doesn't show any results but does a good job of pretending to work
