2924M-XL

Hello,

I have 2924M-XL with 12.0(5.1)XP IOS.I have Ip phones connected to it and pcs are connected to the IP phones.PCs and Ip phones are in same subnet.

Is there any way we can configure QOS and voice vlan on this particular switch.

Looks like 2924 does not support voice vlan.What about QOS?

Thanks in advance.

Re: 2924M-XL

Thanks for the above link.But it is not taking any switchport priority extend cos commands.

What does switchport priority default do.

Thanks in advance.

"What does switchport priority default do. "

Here's the information from the command reference:

http://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/29_35wc6/cli/clicmds.htm#42661

And from the FAQ:

Q. Do the Catalyst 2900 XL and 3500 XL series switches honor the incoming Class of Service (CoS) values in dot1p tags from IP phones?

A. Yes, Catalyst 2900 XL and 3500 XL series switches do honor the incoming Class of Service (CoS) value in the dot1q tag. All the ports are considered trusted ports by default. Since dot1q does not tag the native VLAN traffic, you need to issue the switchport priority default <0-7> interface level configuration command to classify the incoming untagged packet as desired. The switchport priority default <0-7> command can be issued to provide CoS equivalent egress scheduling. Also, if the egress port is a trunk port, the ingress CoS or port default priority configuration will be marked in the outgoing frames as CoS values for the far-end device to treat them with the desired higher priority.

Sorry I can't explain it in detail or with examples. I was thinking that the FAQ might have an answer for your original question.

Re: 2924M-XL

The switchport priority extend cos command seems to be available on the 3500XL and not on the 2900XL.
