The following actions must be completed.
-
A QoS DSCP-to traffic class map must exist.
-
For all devices, the qos trust dscp must be enabled
before applying a qos dscp-to-traffic class map on
a Layer 2 switch port.
Note
On the Layer 2 switch port, qos trust dscp cannot be disabled
before removing the applied qos dscp-to-traffic class map.
-
Enter global configuration mode.
device# configure terminal
-
Enter interface configuration mode.
device(config)# interface ethernet 1/2
-
Activate the QoS DSCP-to-traffic class map on the interface.
device(conf-if-eth-1/2)# qos dscp-traffic-class dscpTcMap
-
Return to privileged EXEC mode.
device(conf-if-eth-1/2)# end
-
Verify the configuration
device# show qos maps dscp-traffic-class
Dscp-to-Traffic-Class map 'dscpTcMap'
{x/y: traffic-class = x, drop-precedence = y & dscp = d1d2}
