Chapter 52 Configuring QoS
Configuring QoS on the Switch
To configure the CoS value for a port, perform this task in privileged mode:
This example shows how to configure the port CoS value to 3 for port 1/1:
Console> (enable)
set port qos 1/1 cos
3
Port 1/1 qos cos set to 3
Console> (enable)
To revert to the default CoS value for a port, perform this task in privileged mode:
This example shows how to revert to the default CoS value for port 1/1:
Console> (enable)
clear port qos 1/1 cos
Port 1/1 qos cos setting cleared.
Console> (enable)
Creating Policers
Note
Supervisor Engine 1 with a Layer 2 Switching Engine does not support the commands in this section.
