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-weight command in an output QoS policy (refer to
Allocating Bandwidth to Queue). The bandwidth-weight command in QOS-POLICY-OUT mode supersedes the
service-class bandwidth-weight command.
• Guarantee a minimum bandwidth to queues globally.
CONFIGURATION mode
service-class bandwidth-weight
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 configure with vlan-stack access.
• If you apply a service policy that contains an ACL to more than one interface, FTOS 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; in this case, INTERFACE mode
must be in Switchport mode.
Creating Output Policy Maps
Creating output policy maps is supported on the Z9000 platform.
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
Specifying an Aggregate QoS Policy
To specify an aggregate QoS policy, use the following command.
• Specify an aggregate QoS policy.
POLICY-MAP-OUT mode
