On each port you will definitely give a voice vlan and a data vlan.. say, the data vlan 1 = 100, data vlan 2 = 200 , you will configure 2 IP DHCP pools on your 3550 and give layer 3 IP adderesses for each of these VLAN... eg
VLAN 100 Layer 3 IP - 192.168.78.1
VLAN 200 Layer 3 IP - 10.20.20.1
You can configure the following DHCP commands on your 3550:
ip dhcp excluded-address 192.168.78.1 192.168.78.10
ip dhcp excluded-address 10.20.20.1 10.20.20.10
ip dhcp pool testpool
network 192.168.78.0 255.255.255.0
ip dhcp pool testpool1
network 10.20.20.0 255.255.255.0
Now, when a user connects from VLAN 100, the DHCP server will give an IP from 192.168.78.0, since the VLAN 100 layer 3 is defined on the switch on that range.. similar thing happens for VLAN 200... so, you can cover up many VLANs with the same switch giving the IP address...
Hope this helps.. all the best.. rate replies if found useful..
In addition to Raj's post, Please configure the switch ports as following:
interface fa 0/1
switchport mode access
switchport access vlan 100
switchport voice vlan 200
This will work out for you and you will get the proper ip address from the respective pools.Please do not configure the switchports as trunk ports where you will connect the IP phones.Configure the ip phone ports as mentioned above.
Just configure the uplink ports between the 2 350 as trunk and do the routing for the vlans only at one of the 3550 switch.
