Options for assigning priority

Priority control options for packets carrying a specified VLAN-ID include:

  • 802.1p priority

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

(For operation when other QoS classifiers apply to the same traffic, see Classifiers for prioritizing outbound packets.)

NOTE:

QoS with VID priority applies to static VLANs only, and applying QoS to dynamic VLANs created by GVRP operation is not supported. A VLAN must exist while a subject of a QoS configuration, and eliminating a VLAN from the switch causes the switch to clear any QoS features configured for that VID.
