QoS Commands qos dscp-mutation The qos dscp-mutation Global Configuration mode command applies the DSCP Mutation map to a system DSCP trusted port. To return to the trust state with no DSCP mutation, use the no form of this command. Syntax qos dscp-mutation no qos dscp-mutation Parameters There are no parameters for this command. Default Setting This command has no default configuration. Command Mode Global Configuration mode. Command Usage The DSCP to DSCP mutation map is applied to a port at the boundary of a Quality of Service (QoS) administrative domain. If two QoS domains have different DSCP definitions, use the DSCP to DSCP mutation map to match one set of DSCP values with the DSCP values of another domain. Apply the DSCP to DSCP mutation map only to ingress and to DSCP-trusted ports. Applying this map to a port causes IP packets to be rewritten with newly mapped DSCP values at the ingress ports. If the DSCP to DSCP mutation map is applied to an untrusted port, class of service (CoS) or IP-precedence trusted port, this command has no immediate effect until the port becomes DSCP-trusted. Example The following command applies the DSCP Mutation map to system DSCP trusted ports. Console(config)# qos dscp-mutation HP PC Blade Switch CLI Reference Guide www.hp.com 18-29
