Aggregate input/output QoS policy applies to all the port ingoing/outgoing traffic. Aggregateinput/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 areignored.2. If an aggregate input QoS policy and a per-class input QoS policy coexist, the aggregateinput 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 QoSpolicy, the rate police configurations in the per-class QoS are ignored. Markingconfigurations 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 andqueuing configurations in the aggregate output QoS policy (if existing) are ignored. Eachqueue uses default scheduling and queuing configuration (weighted random earlydetection [WRED] and Bandwidth).4. If the aggregate output QoS policy and per-queue output QoS policy coexist, theaggregate output QoS policy preempts a per-queue output QoS policy on egress trafficconditioning (rate-limit). In other words, if a rate limit configuration exists in theaggregate output QoS policy, the rate limit configurations in per-queue output QoSpolicies are ignored. Scheduling and queuing configurations (WRED and Bandwidth) inthe per-queue output QoS policy still apply to each queue.RelatedCommandspolicy-map-input – creates an input policy map.policy-map-output – creates an output policy map (E-Series Only).policy-map-inputCreate an input policy map.C-Series, E-Series, S-Series, Z-Series, S4810Syntax policy-map-input policy-map-name [layer2]To remove an input policy map, use the no policy-map-input policy-map-name[layer2] command.Parameterspolicy-map-name Enter the name of the policy map in character format (32 charactersmaximum).layer2 (OPTIONAL) Enter the keyword layer2 to specify a Layer 2 ClassMap.
