Network Queue QoS Policies
Network queue policies define the network forwarding class queue characteristics. Network queue
policies are applied on egress on core network ports and on ingress on . Network queue policies
can be configured to use as many queues as needed This means that the number of queues can
vary. Not all policies will use eight queues like the default network queue policy.
The queue characteristics that can be configured on a per-forwarding class basis are:
•
Committed Buffer Size (CBS) as a percentage of the buffer pool
•
Maximum Buffer Size (MBS) as a percentage of the buffer pool
•
High Priority Only Buffers as a percentage of MBS
•
Peak Information Rate (PIR) as a percentage of egress port bandwidth
•
Committed Information Rate (CIR) as a percentage of egress port bandwidth
Network queue policies are identified with a unique policy name which conforms to the standard
router alphanumeric naming conventions.
