Different gateway by vLan.

[winter_stuart]

Good afternoon,

We have SG300 52 port switches. These can be L2 or L3. All the PC's tether to the network through the Cisco phones. The PC's get their IP and gateway information from our DHCP server and operate down GATEWAY1. The Cisco phones receive their IP and gateway information from Cisco Call Manager and operate down GATEWAY2.

We have been having issues which seems to be the PC traffic trying to go down GATEWAY2 so I'm looking to vLAN the traffic.

Can I please be pointed in the correct direction bearing in mind that the PC's tether to the network through the phones?

Thanks Mark,

The switches have Auto-Voice vLAN enabled. Does this mean I just need to create a vLAN for DATA and assign all ports to it? Or that the vLAN is already in place since all ports are on default vLAN1?

I believe you still need to create the vlan for voice , 5 step process for auto voice vlan in this doc
