Guaranteeing Bandwidth to dot1p-Based Service Queues
To guarantee bandwidth to dot1p-based service queues, use the following command.
Apply this command in the same way as the bandwidth-percentage command in an output QoS policy (refer to Allocating Bandwidth
to Queue
). The bandwidth-percentage command in QOS-POLICY-OUT mode supersedes the service-class bandwidth-
percentage
command.
Guarantee a minimum bandwidth to queues globally.
CONFIGURATION mode
service-class bandwidth-percentage
Applying an Input Policy Map to an Interface
To apply an input policy map to an interface, use the following command.
You can apply the same policy map to multiple interfaces, and you can modify a policy map after you apply it.
You cannot apply a class-map and QoS policies to the same interface.
You cannot apply an input Layer 2 QoS policy on an interface you also congure with vlan-stack access.
If you apply a service policy that contains an ACL to more than one interface, Dell Networking OS uses ACL optimization to conserve
CAM space. The ACL optimization behavior detects when an ACL exists in the CAM rather than writing it to the CAM multiple times.
Apply an input policy map to an interface.
INTERFACE mode
service-policy input
Specify the keyword layer2 if the policy map you are applying a Layer 2 policy map.
Creating Output Policy Maps
1 Create an output policy map.
CONFIGURATION mode
policy-map-output
2 After you create an output policy map, do one or more of the following:
Applying an Output QoS Policy to a Queue
Specifying an Aggregate QoS Policy
Applying an Output Policy Map to an Interface
3 Apply the policy map to an interface.
Applying an Output QoS Policy to a Queue
To apply an output QoS policy to a queue, use the following command.
Apply an output QoS policy to queues.
INTERFACE mode
service-queue
