Non-Cisco Phone and Cisco switch 2950

Unanswered Question
Feb 14th, 2007

Hi,

I am stuck at the moment with a non-cisco phone (SNOM 300) and Cisco switch 2950. PC connected to IP Phone.

Configured voice vlan as 172. access vlan native.

I understand Cisco phones with CDP to be able to connect to the network.

What do I need to consider to ensure:

1) the switch

2) the non-cisco phone

all to work correctly?

I have this problem too.

I doubt the SNOM300 can read CDP so it won't grab the voice vlan information. Just configure the port as an access port.

I dont think this Phone would support CDP and therefore u'd have to make the port as a trunk. Also, a lot of non cisco devices have issues with CDP msgs being sent, so disabling CDP would also be a good idea

thanks guys,

definitely does not support CDP.

This is what I should do:

1. Set the port as trunk.

2. Assign VLAN ID 172 to the IP Phone.

3. Then the eth2 on the IP phone to a PC on access VLAN.

4. Disable CDP (consequences of this apart from IP Phone)

thx
