per class QoS are ignored. Marking configurations in per class input QoS policy still apply to each
queue.
E-Series
Aggregate input/output QoS policy applies to all the port ingoing/outgoing traffic. Aggregate input/
output QoS policy can co-exist with per queue input/output QoS policies.
1. If only an aggregate input QoS policy exists, input traffic conditioning configurations (rate-police)
will apply. Any marking configurations in the aggregate input QoS policy will be ignored.
2. If an aggregate input QoS policy and a per-class input QoS policy co-exist, then the aggregate
input QoS policy will preempt the per-class input QoS policy on input traffic conditioning
(rate-police). In other words, if a rate police configuration exists in the aggregate QoS policy, the
rate police configurations in the per-class QoS are ignored. Marking configurations in the per-class
input QoS policy still apply to each queue.
3. If only an aggregate output QoS policy exists, egress traffic conditioning configurations (rate-limit
and rate-shape) in the aggregate output QoS policy will apply. Scheduling and queuing configura-
tions in the aggregate output QoS policy (if existing) are ignored. Each queue will use default
scheduling and queuing configuration (Weighted Random Early Detection (WRED) and Band-
width).
4. If the aggregate output QoS policy and per-queue output QoS policy co-exist, the aggregate output
QoS policy will preempt a per-queue output QoS policy on egress traffic conditioning (rate-limit).
In other words, if a rate limit configuration exists in the aggregate output QoS policy, the rate limit
configurations in per-queue output QoS policies are ignored. Scheduling and queuing configura-
tions (WRED and Bandwidth) in the per-queue output QoS policy still apply to each queue.
