pre-Version
6.1.1.1 Introduced on the E-Series.
Usage
Information
C-Series and S-Series
Aggregate input/output QoS policy applies to all the port ingoing/outgoing traffic. Aggregate
input/output QoS policy can coexist with per queue input/output QoS policies.
1. If only aggregate input QoS policy exists, input traffic conditioning configurations (rate-
police) apply. Any marking configurations in aggregate input QoS policy are ignored.
2. If aggregate input QoS policy and per class input QoS policy coexist, aggregate input QoS
policy preempts per class input QoS policy on input traffic conditioning (rate-police). In
other words, if rate police configuration exists in the aggregate QoS policy, the rate
police configurations in 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 coexist with per queue input/output QoS policies.
1. If only an aggregate input QoS policy exists, input traffic conditioning configurations
(rate-police) apply. Any marking configurations in the aggregate input QoS policy are
ignored.
2. If an aggregate input QoS policy and a per-class input QoS policy coexist, the aggregate
input QoS policy preempts 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 apply. Scheduling and
queuing configurations in the aggregate output QoS policy (if existing) are ignored. Each
queue uses default scheduling and queuing configuration (weighted random early
detection [WRED] and Bandwidth).
4. If the aggregate output QoS policy and per-queue output QoS policy coexist, the
aggregate output QoS policy preempts 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 configurations (WRED and Bandwidth) in
the per-queue output QoS policy still apply to each queue.
