# Creating or Modifying Classifier Control Lists for VLAN Policy Lists

You can create or modify a classifier control list that can be used only in VLAN policy lists.

- Issue the vlan classifier-list command:
  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

  | Note: You cannot configure classifier control lists (CLACLs) for policy lists to be attached to VLAN interfaces, without specifying the criteria by which the router defines a packet flow. Although the carriage return, <cr>, option is displayed when you type a question mark (?) after entering the vlan classifier list classiferName command without defining any other keyword or CLACL criterion, an error message is displayed when you press Enter to configure the VLAN CLACL with only the name. You must specify at least one criterion for the VLAN CLACL to be successfully configured.
