Hi,
If you want to pass VLANs from one switch to another, you have to define
both ends of the link as trunk. Also you have to have the same VLANs
configured in both switches. And third - your "second" switch should support
Cisco IP Phones. What model is your additional switch? If it does not
support IP Phones and "auxiliary VLAN", you may need to configure port as a
trunk. And as a "last resort", you may need to configure "some" ports to be
just a "phone ports" and other ports to be "PC ports" with the only one VLAN
configured on the port.
Good luck,
Mike

Hello let me explain what I am trying to do. I have a 48 port Cisco
Catalyst that I have no ports free. I have phone that need to be
hooked up. I have the power supply for them so i dont need POE. What i
want to do is take a port a connect that port to another switch which
I will use on for the phones. I still want the phones to hand out DHCP
addresses to my pcs that are connected to the new phones.
I configured a port but it is handing out DHCP address from the Phones
Vlan not my data Vlan.
I have 4 Vlans. 1 for phones, 1 data, 1 management and 1 wireless
access.
