Scott,

From the 3550 Configuration Guide:

This example shows how to define the DSCP-to-DSCP-mutation map. All the
entries that are not explicitly configured are not modified (remain as
specified in the null map):

Switch# configure terminal
Switch(config)# mls qos map dscp-mutation mutation1 1 2 3 4 5 6 7 to 0
Switch(config)# mls qos map dscp-mutation mutation1 8 9 10 11 12 13 to 10
Switch(config)# mls qos map dscp-mutation mutation1 20 21 22 to 20
Switch(config)# mls qos map dscp-mutation mutation1 30 31 32 33 34 to 30
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# mls qos trust dscp
Switch(config-if)# mls qos dscp-mutation mutation1

HTH,

Joe Martin

Subject: Aggregating DSCP values

I am going to keep digging at it, but I am stumped now. I believe I
understand how to aggregate precedence levels, but I am clueless on how
to aggregate DSCP values. Is there a way to do this? I have browsed some
url's and looked at the two RFC's, but nothing is jumping out at me yet.
Guess I have to dig a little deeper.

Let us say there is a task to group DSCP 28 through 32. How would one do
this without having to create 5 ACL's for each value?

Thank You,
scott
