qos cos-mutation

Applies a CoS Mutation map on a physical or a port channel interface. Use this command to apply the all-zero-map special CoS Mutation map.

Syntax

qos cos-mutation [ all-zero-map | cos-mutation-map-name ]

no qos cos-mutation [ all-zero-map ]

all-zero-map: Applies the special all-zero-map CoS Mutation map where any incoming CoS value is mapped to the value 0 (zero) before the packet is sent out.
cos-mutation-map-name: Applies the named CoS Mutation map to the interface.

Interface Configuration mode

This command can only be applied to physical and port channel interfaces in the Layer 2 Trunk mode.

The no form of this command disassociates the QoS map from the interface.

This command returns an error when it is applied on a Layer 3 physical or a port channel interface.

This command returns an error when it is applied on a Layer 2 physical or a port channel interface in Layer 2 Access mode.

You cannot change the physical or port channel's mode after applying a CoS Mutation map.

SLX 9740 and Extreme 8820

This example shows the application of a CoS Mutation map on a physical interface. The QoS CoS Mutation map should already exist.

SLX# configure terminal
SLX (config)# interface Ethernet 0/3
SLX (conf-if-eth-0/3)# qos cos-mutation test-cos-mut-map-1 
SLX (conf-if-eth-0/3)#

This example show the application of the special all-zero-map QoS CoS Mutation map on to a physical interface.

SLX# configure terminal
SLX (config)# interface Ethernet 0/3 
SLX (conf-if-eth-0/3)# qos cos-mutation all-zero-map
SLX (conf-if-eth-0/3)#

This example shows how to remove a QoS CoS mutation map that is associated with a physical interface.

SLX# configure terminal
SLX (config)# interface Ethernet 0/3 
SLX (conf-if-eth-0/3)# no qos cos-mutation 
SLX (conf-if-eth-0/3)#
