[c-nsp] Basic DHCP config assistance

[Marcello Pedersen]

Hi,
 
I am trying to get DHCP to work on multiple VLANs. My lab is pretty simple:
 
Lucent Firewall --> 2651XM router and DHCP  --> 3560 PoE Switch
 
I am trying to have phones on VLAN 3 get IP from 265x1XM as well as PCs on VLAN 1.
 
PCs get an IP address however the phones don't. I think it is because my VLAN 3 has no IP address but does it need to have an IP?
 
Thanks!
Marcello
