Implementation Information

The Dell Networking QoS implementation complies with IEEE 802.1p User Priority Bits for QoS Indication.

It also implements these Internet Engineering Task Force (IETF) documents:

RFC 2474, Definition of the Differentiated Services Field (DS Field) in the IPv4 Headers

RFC 2475, An Architecture for Differentiated Services

RFC 2597, Assured Forwarding PHB Group

RFC 2598, An Expedited Forwarding PHB

You cannot configure port-based and policy-based QoS on the same interface.

Port-Based QoS Configurations

You can configure the following QoS features on an interface.

You cannot simultaneously use egress rate shaping and ingress rate policing on the same virtual local area network

Setting dot1p Priorities for Incoming Traffic

Dell Networking OS places traffic marked with a priority in a queue based on the following table.

If you set a dot1p priority for a port-channel, all port-channel members are configured with the same value. You cannot assign a dot1p value

to an individual interface in a port-channel.
