Options for assigning priority

The global QoS packet-marking options for packets that carry a specified VLAN ID include:
  • 802.1p priority

  • DSCP policy: Assigning a new DSCP and 802.1p priority


A global VLAN ID classifier marks priority levels only in packets received on static VLANs. Packets received in a dynamic VLAN created by GVRP operation are not marked by a global VLAN ID classifier.

The VLAN ID used as a global QoS classifier must currently exist on the switch. If you remove a VLAN from the switch, all global QoS configurations that use the VLAN ID for packet marking are also removed.
