Chapter 2: Creating Policies

vlan classifier-list

! Use to create or modify a VLAN classifier control list.

! Use the following keywords to configure the list:

! traffic-class—Matches packets with a traffic class that you defined using

the traffic-class command

! color

" green—Matches packets with color green, indicating a low drop

preference

" yellow—Matches packets with color yellow, indicating a medium drop

preference

" red—Matches packets with color red, indicating a high drop preference

! user-packet-class—Matches packets with the specified user packet class

value

! user-priority—Specifies the value of the user-priority bits, which you

define in the policy list

! Example

host1(config)#vlan classifier-list lowLatencyLowDrop user-priority 7

host1(config)#vlan classifier-list lowLatencyLowDrop user-priority 6

host1(config)#vlan classifier-list lowLatency user-priority 5

host1(config)#vlan classifier-list excellentEffort user-priority 4

host1(config)#vlan classifier-list bestEffort user-priority 3

host1(config)#vlan classifier-list bestEffort user-priority 2

host1(config)#vlan classifier-list bestEffort user-priority 1

host1(config)#vlan classifier-list bestEffort user-priority 0

! Use the no version to remove the classifier control list.

Creating Policy Lists

You create a policy rule by specifying a policy action within a classifier group that

references a CLACL. These rules become part of a policy list that you can attach to

an interface as either an input policy, secondary-input policy, or output policy. The

router applies the rules in the attached policy list to the packets traversing that

interface.

You can apply policy lists to packets:

! Arriving at an interface (input policy); on IP and IPv6 interfaces the packets

arrive before route lookup

! Arriving at the interface, but after route lookup (secondary input policy);

secondary input policies are supported only on IP and IPv6 interfaces

! Leaving an interface (output policy)

NOTE: Do not use the asterisk (*) for the name of a classifier list. The asterisk is

used as a wildcard for the classifier-group command.
