Using QoS Classifiers To Configure Quality of Service for Outbound Traffic
QoS VLAN-ID (VID) Priority
QoS Classifier Precedence: 5
The QoS protocol option enables you to use the VLAN-ID quantities listed
below as QoS classifiers.
■
5300xl Switches: Up to 256 VIDs
■
3400cl/6400cl Switches: Up to 120 VIDs
Where a particular VLAN-ID classifier has the highest precedence in the switch
for traffic in that VLAN, then traffic received in that VLAN is marked with the
VID classifier's configured priority level. Different VLAN-ID classifiers can
have differing priority levels.
Options for Assigning Priority. Priority control options for packets carry
ing a specified VLAN-ID include:
■
802.1p priority
■
DSCP policy (Assigning a new DSCP and an associated 802.1p priority;
inbound packets must be IPv4.)
(For operation when other QoS classifiers apply to the same traffic, refer to
"Classifiers for Prioritizing Outbound Packets" on page 8-9.)
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.
Assigning a Priority Based on VLAN-ID
This option assigns a priority to all outbound packets having the specified
VLAN-ID (VID). You can configure this option by either specifying the VLAN
ID ahead of the qos command or moving to the VLAN context for the VLAN
you want to configure for priority.
