WAN Interface Bandwidth Priorities

ArubaOS supports minimum bandwidth guarantees per traffic class, and allows critical delay-sensitive applications like voice and video to use more bandwidth and/or be scheduled with higher priority. Each interface can be associated with a scheduler profile that supports four queues with different priority levels. If you use session ACLsAccess Control List. ACL is a common way of restricting certain types of traffic on a physical port. to define traffic policies on the managed device, you can use the scheduler profile to automatically associate these different priority levels assigned by these policies to a scheduler profile queue.


For information on creating a traffic policy that assigns 802.1p priority levels to a specific application or application type, see Configuring Firewall Policies

Each scheduler profile queue is assigned a priority level and one of the following scheduler discipline types:

Strict priority: The queue service is based exclusively on the priority of the queue, where the lower priority queues are not serviced until the higher priority queue is clear. With this option, the highest level priority is guaranteed as much bandwidth as possible, but there can be phases where the 2nd, 3rd and 4th priority queues may receive little or no bandwidth.

Deficit Round Robin Weight: The queue is assigned a percentage of available bandwidth.


You can define both strict priority and DDR Weight discipline types for a single scheduler profile.
