separate phone and data network on same Cisco 2960x switches
Posted on 2014-12-18
I have a Mitel VOIP phone system and would like to take advantage of the extra network port on the phones by plugging the computers into the phones, and the phones into the wall ports. This will free up ports in our switch stack (2960x for access layer, 3750 for the core and routing) for more devices. Currently, our phones are on a separate Dell switch that we would like to retire. So, how can I best build this? The 2960x switches are in a stack and uplink to a 3750 for vlan routing. Do I need to create the new phone VLAN in both the 2960x and the 3750 switches, or can I just leave everything on VLAN1 (data vlan) on the 2960x stack, trunk the port to the 3750, and ip both the VLAN1 (data) and VLAN2 (phones) on the 3750, and configure QoS on the 2960x stack. Does that make sense? Thanks!
