2. After you create an input QoS policy, do one or more of the following:
Configuring Policy-Based Rate Policing
Setting a dot1p Value for Egress Packets
Configuring Policy-Based Rate Policing
To configure policy-based rate policing, use the following command.
Configure rate police ingress traffic.
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 configuration 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 configure an output QoS policy, do one or more of the following:
Scheduler Strict Policy-based Strict-priority Queueing configuration 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
Configuring Policy-Based Rate Shaping
To configure policy-based rate shaping, use the following command.
Configure rate shape egress traffic.
QOS-POLICY-OUT mode
rate-shape
Allocating Bandwidth to Queue
The switch schedules packets for egress based on Deficit Round Robin (DRR). This strategy offers a guaranteed data rate.
Allocate bandwidth to queues only in terms of percentage in 4-queue and 8-queue systems. The following table shows the
default bandwidth percentage for each queue.
The following table lists the default bandwidth weights for each queue, and their equivalent percentage which is derived by
dividing the bandwidth weight by the sum of all queue weights.
