QoS on Cisco WS-C2950-12 IOS 12.1(22)EA9

I am wondering what is possible to setup for a Cisco WS-C2950-12 to prioritize traffic between 2 ports on the switch but allow a third port also access on of the ports. The setup is as follows:

Port Fa0/1: Time Warner Cable Router Port Fa0/2: Sonicwall Firewall Port Fa0/3: VOIP controller card for our phones

I want the traffic between ports Fa0/3 and Fa0/1 to take precedence over taffic between Fa0/2 and Fa0/1. I tried to figure out a way to use VLANs but I cannot seem to make this work without another piece of equipment. Is there something I can do besides have a router for inter-vlan communication?

Thanks, Josh

Well, you could use your router, provided it has enough interfaces. You will need some sort of layer 3 device to route between the VLANs, be it the switch, a firewall, etc.

Regarding QoS, what problem are you trying to solve?

Here is the guide on QoS for your switch:

Do you have the standard or enhanced image? I believe some of the features aren't there with the standard image.

At any rate, QoS is probably better used when you have more than 1 network device involved - end to end. I probably wouldn't worry about oversubscribing the backplane on this switch. Also, let's say you do mark your outbound packets (to Time Warner). They'll just ignore the DSCP values you set.

The problem I am trying to solve is poor VOIP sound quality. When the network traffic on our Sonicwall firewall is using alot of bandwidth the voice quality on the phones decreases. I need to make sure VOIP traffice takes precedence and always has enough bandwidth.

Thanks, Josh
