Configuring QoS on the Switch
Clearing a DSCP Mutation Map from a VLAN
To clear a DSCP mutation map from a VLAN, perform this task in privileged mode:
This example shows how to clear the association of any VLANs with DSCP mutation map 2:
Console> (enable)
clear qos dscp-mutation-table-map 2
All VLANS in mutation-table-id 2 are cleared.
This example shows how to clear the association of VLANs 3–33 with any DSCP mutation maps:
Console> (enable)
clear qos dscp-mutation-table-map 3-33
VLAN(s) 3-33 are removed from mutation-table-ids.
This example shows how to clear the association of all VLANs with all DSCP mutation maps:
Console> (enable)
clear qos dscp-mutation-table-map all
All VLANs are removed from mutation-table-ids.
Configuring CoS-to-CoS Maps on 802.1Q Tunnel Ports
Ingress Cos-to-CoS mapping is supported on 802.1Q tunnel ports on the WS-X6704-10GE,
WS-X6724-SFP, and WS-X6748-GE-TX switching modules. CoS-to-CoS mapping is disabled on the
ports that are not configured as 802.1Q tunnel ports.
Defining a CoS-to CoS Map
To define a CoS-to-CoS map, perform this task in privileged mode:
This example shows how to define the CoS-to-CoS map:
Console> (enable)
set qos cos-cos-map 3 2 1 4 5 6 7 4
QoS cos-cos-map set successfully.
Console> (enable)
