[cisco-voip] Power over Ethernet

[Kurt De Neef (Europe)]

Hi Kevin,

 

You need CDP to be enabled indeed in order to have the router be able to
recognize the phones and give power accordingly or not.

Okay so this is a newbie question, but I can't seem to find the answer.

 

I have an MGCP Gateway on a 2811 

this is a small 5 person office so they have an Ethernet module on the
router. (NM-16ESW) with a power card (PPWR-DCARD-16ESW).

 

This weekend I tried to cut over the site and I can't get power to the
phones.

 

the Config looks like this:

 

Interface FastEthernet1/1

decription Sue's Phone and PC

switchport access Vlan 4

switchport voice vlan 3

duplex full

speed 100

power inline auto 

mls qos cos override

spanning-tree portfast

 

according to the router my options are power inline (auto, never).  Do I
need cdp enabled on the port to detect the phone?  How do I get power to
the phones?

 

Much appreciated
