Hi

I have a call manager on the Cisco 3745. The Ip-phone are connected on the Catalyst 3550.

I configured 2 vlan on the network as show below

All the 24 port of the catalyst 3550 have the same configuration

Everything is working fine

Now I need to add another switch to extend the LAN

I got the catalyst 500 series

I want to know how I can configure the port of the catalyst 500 in other to integrate it in the network (support Vlan voice and Vlan DATA and work with the catalyst 3550 and the router 3745) ?

ROUTER 3745
