awplus(config)#interface <port-number>
awplus(config-if)#mls qos cos <0-7>
The value you change the CoS to is not used to look up the initial egress queue setting; the
mls qos queue command still determines the queue for untagged packets.
Classification
The process of assigning packets to class maps requires a two stage configuration.
First, create a class map by entering the following command:
awplus(config)#class-map <name>
Then, specify the parameters for classifying traffic, by using the match command. You can
match on an ACL or on a number of other parameters, as the following table shows:
For detailed information about ACLs and the match commands, see the Note How To
Configure Hardware Filters on SwitchBlade x908, x900-12XT/S, and x900-24 Series Switches.
Premarking
Premarking happens after ingress, before the traffic has been policed.
There are two mutually exclusive methods available for premarking:
z setting the new values explicitly for all packets that match a certain class map, or
z using the mark-dscp map to apply new values to the packets.
