I'm struggling to find any QoS guides that would contain any information for a 4506 runnign CatOs, all the config guides only seem to be tailored for IOS.

Does anyone have any experience/documentation for configuring QoS on a 4506 running CatOS?

I'm only after some basic QoS setup for voice, trust cos 3 and 5, etc

Use the QOS CatOS config guides for the 6500s, they're nearly identical.

Hope that helps

thanks for the reply, i've seen that doc already, unfortunately, all the config links seem to lead to IOS configuration guide :-(

The configuration guides for Catalyst 4x00 CatOS are now in the 'end of life/end of sale' documentation pile...

Here is the latest Cat 4000 software 8.3 & 8.4 guides for QoS.


There isn't much.... All interfaces are 2q1t and all you can do is Map CoS values to queues, so only Layer-2 802.1p CoS is supported (no Layer-3 DSCP/IP Precedence support). You can set a default CoS value (i.e. rewrite or add an 802.p priority to all incoming frames) and there is no support for ingress or egress polcies (like there is with the Sup2+ and IOS on the 4500).
