Configuring The Trust State Of Ethernet Lan Ports - Cisco WS-SUP32-GE-3B - Supervisor Engine 32 Software Configuration Manual

Configuring PFC QoS
When configuring the internal DSCP to egress CoS map, note the following information:
•
•
•
This example shows how to configure internal DSCP values 0, 8, 16, 24, 32, 40, 48, and 54 to be mapped
to egress CoS value 0:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# mls qos map dscp-cos 0 8 16 24 32 40 48 54 to 0
Router(config)# end
Router#
This example shows how to verify the configuration:
Router# show mls qos map | begin Dscp-cos map
Dscp-cos map:
<...Output Truncated...>
Router#
In the Dscp-cos map display, the CoS values are shown in the body of the matrix; the first digit of the
Note
DSCP value is in the column labeled d1 and the second digit is in the top row. In the example shown,
DSCP values 41 through 47 all map to CoS 05.

Configuring the Trust State of Ethernet LAN Ports

By default, all ports are untrusted. You can configure the port trust state on all Ethernet LAN ports ports.
On non-Gigabit Ethernet 1q4t/2q2t ports, you must repeat the trust configuration in a class map.

You can enter up to 8 DSCP values that PFC QoS maps to a CoS value.
You can enter multiple commands to map additional DSCP values to a CoS value.
You can enter a separate command for each CoS value.
