Mapping A Cos Value To A Host Destination Mac Address/Vlan Pair - Cisco WS-C6506 Software Manual

Chapter 52 Configuring QoS
Enabling a CoS-to CoS Map on a Port
To enable a CoS-to-CoS map on a port, perform this task in privileged mode:
Task
Step 1 Enable the CoS-to-CoS map on an 802.1Q tunnel
port.
Step 2
Verify the port QoS trust configuration.
Console> (enable) set port qos 1/1 trust trust-cos
Port 1/1 qos set to trust-cos
Console> (enable)
Note The CoS-to-CoS map is automatically disabled when the port trust is not trust-cos for the 802.1Q tunnel
ports.
Clearing a CoS-to-CoS Map
To clear a CoS-to-CoS map, perform this task in privileged mode:
Task
Step 1 Clear the CoS-to-CoS map on an 802.1Q tunnel
port.
Step 2
Verify the port QoS configuration.
This example shows how to clear the CoS-to-CoS mapping:
Console> (enable) clear qos cos-cos-map
QoS cos-cos-map setting restored to default.
Console> (enable)

Mapping a CoS Value to a Host Destination MAC Address/VLAN Pair

Note QoS supports this command only with a Layer 2 Switching Engine.
To map a CoS value to all frames that are destined for a particular host destination MAC address and
VLAN number value pair, perform this task in privileged mode:
Task
Step 1 Map a CoS value to a host destination MAC
address/VLAN pair.
Step 2 Verify the configuration.
