Creating an Input QoS Policy
To create an input QoS policy, use the following steps.
1. Create a Layer 3 input QoS policy.
CONFIGURATION mode
qos-policy-input
Create a Layer 2 input QoS policy by specifying the keyword layer2 after the qos-policy-input command.
2. After you create an input QoS policy, do one or more of the following:
Conguring Policy-Based Rate Policing
Setting a dot1p Value for Egress Packets
Conguring Policy-Based Rate Policing
To congure policy-based rate policing, use the following command.
• Congure rate police ingress trac.
QOS-POLICY-IN mode
rate-police
Setting a dot1p Value for Egress Packets
To set a dot1p value for egress packets, use the following command.
• Set a dscp or dot1p value for egress packets.
QOS-POLICY-IN mode
set mac-dot1p
Constraints
The systems supporting this feature should use only the default global dot1p to queue mapping conguration as described in Dot1p
to Queue Mapping Requirement.
Creating an Output QoS Policy
To create an output QoS policy, use the following commands.
1. Create an output QoS policy.
CONFIGURATION mode
qos-policy-output
2. After you congure an output QoS policy, do one or more of the following:
Scheduler Strict — Policy-based Strict-priority Queueing conguration is done through scheduler strict. It is applied to Qos-
policy-output. When scheduler strict is applied to multiple Queues, high queue number takes precedence.
Allocating Bandwidth to Queue
Specifying WRED Drop Precedence
Conguring Policy-Based Rate Shaping
To congure policy-based rate shaping, use the following command.
• Congure rate shape egress trac.
QOS-POLICY-OUT mode
rate-shape
