Honoring dot1p Values on Ingress Packets
Dell Networking OS honors dot1p values on ingress packets with the Trust dot1p feature.
The following table specifies the queue to which the classified traffic is sent based on the dot1p value.
Table 43. Default dot1p to Queue Mapping

The dot1p value is also honored for frames on the default VLAN. For more information, refer to
Tagged Frames on the Default VLAN
• Enable the trust dot1p feature.
POLICY-MAP-IN mode
trust dot1p
Mapping dot1p Values to Service Queues
All traffic is by default mapped to the same queue, Queue 0.
If you honor dot1p on ingress, you can create service classes based the queueing strategy in
dot1p Values on Ingress Packets
. You may apply this queuing strategy globally by entering the following
command from CONFIGURATION mode.
• All dot1p traffic is mapped to Queue 0 unless you enable
service-class dynamic dot1p
on an
interface or globally.
• Layer 2 or Layer 3 service policies supersede dot1p service classes.
• Create service classes.
INTERFACE mode
service-class dynamic dot1p
Guaranteeing Bandwidth to dot1p-Based Service Queues
To guarantee bandwidth to dot1p-based service queues, use the following command.
Apply this command in the same way as the
bandwidth-percentage
command in an output QoS
policy (refer to
bandwidth-percentage
command in QOS-
POLICY-OUT mode supersedes the
service-class bandwidth-percentage
command.
• Guarantee a minimum bandwidth to queues globally.
CONFIGURATION mode
service-class bandwidth-percentage
