You can use class-maps and policy-maps on the 3550. If you are using it
as a layer 3 switch, you would apply the service-policy to the VLAN
interface. If you are using it as a layer 2 switch, you will need to
apply the service-policy to all interfaces associated with vlan 22.
So, you would configure an access-list to match all packets, then create
a class-map to match the access-group of the list you just configured,
then you would create a policy-map that matches the class-map you just
configured and sets the ip precedence to 3. Next, you would apply the
service-policy as needed.
You can then verify it is working by issuing the "show policy-map
interface <interface>" command
Hope this helps

Subject: QOS on 3550
I am about to flip out. This is really confusing me.
One of my tasks has the following on a vendor lab:
Configure per port per vlan to follow the following criteria:
Int fa0/x is an access port in vlan 22. Make sure that all packets in
this
vlan are set with an ip precedence of 3. How exactly is this done?
I have no issues with any QOS problems when we are talking routers, but
this
is confusing me. I have looked at the per-port per-vlan basis on the DOC
cd
but it's still confusing me a bit.
