adding voice vlan existing network

Good day, I have searched cisco fourms for a while for a solution but here is my situation.

I currently have a data network with defualt vlan 1 and a Voice network on vlan 1 also.

My data network is 10.20.60.0/23

My Voice network is 192.168.2.0/24 

Our network has an ASA and 2950's and the Avaya 4550 poes

On our asa we have a port that is labeled voice and has the Ip of 192.168.2.1 . Also route between same security is on

All my phones are static and all the phones are plugged into Avaya 4550T poe's. and the gateway for my phones are 192.168.2.1

Also some pc's are connected to the phone for service.

I want  to be able to separate my DATA and VOICE network we have a Newly acquired 2921 to aid with this setup.

Can I keep my default Vlan 1 along with  and adding vlan 2 for voice to accomplish my task. I have read some forums showing some configs like;

interface FastEther0/1

switchport mode access

switchport voice vlan 2

But not sure what do with My ASA and my 2921

Note my ASA is connected via Site-to-Site to another office of ours.. Any advice, help, examples,  anything  I would appreciate it.

You can connect the ASA directly to the 2921 and transfer the routing configuration over to the 2921. From there, you can continue using one port for each VLAN or you can trunk as you please.

Also, keep in mind that you can change the Data VLAN without messing up connectivity, but do it when network use is low. It's always best to operate away from VLAN 1 from a security perspective.

Roger,

You should be able to do this. Can you draw up a quick diagram of how your topology is? I'm trying to envision the ASA and 2921, but I'm having a hard time. Do you have a dedicated port on the ASA that supports the 192.168.2.0/24 subnet?

HTH,
John

Re: adding voice vlan existing network

OK.... sounds like a plan..

Scenario 1: Lets say I have port 0/0 of the 2921 connected to the ASA how that port will be configured? Would it have an IP? Also on the 2921 i have port 1/1 configured with all my sub interfaces which will be that one connected port to the switch.

Just want to know how data will pass from asa to 2921.

Also I think I will use vlan 10 for data and use vlan 20 for voice

Thanks,
