DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide Usage Guideline An aggregate policer can be shared by different policy map classes in a policy map. It cannot be shared by separate policy maps. Example This example shows how an aggregate policer named "agg-policer5" with a single rate two color policer is configured. This named aggregator policer is applied as the service policy for the class 1 and class 2 traffic class in the policy 2 policy map. Switch# configure terminal Switch(config)# mls qos aggregate-policer agg-policer5 10 1000 exceed-action drop Switch(config)# policy-map policy2 Switch(config-pmap)# class class1 Switch(config-pmap-c)# police aggregate agg_policer5 Switch(config-pmap-c)# exit Switch(config-pmap)# class class2 Switch(config-pmap-c)# police aggregate agg_policer5 Switch(config-pmap-c)# 63-5 mls qos cos This command is used to configure the default Class of Service (CoS) value of a port. Use the no form of this command to revert to the default setting. mls qos cos {COS-VALUE | override} no mls qos cos Parameters COS-VALUE override Specifies to assign a default CoS value to a port. This CoS will be applied to the incoming untagged packets received by the port. Specifies to override the CoS of the packets. The default CoS will be applied to all incoming packets, tagged or untagged, received by the port. Default By default, this CoS value is 0. By default, override is not specified. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline When the override option is not specified, the CoS of the packets will be the packet's CoS if the packets are tagged, and will be the port default CoS if the packet is untagged. When the override option is specified, the port default CoS will be applied to all packets received by the port. Use the override keyword when all incoming packets on certain ports deserve a higher or lower priority than packets that enter from other ports. Even if a port was previously set to trust DSCP or CoS, this command overrides that trust state, and all CoS values on the incoming packets are changed to the default CoS value that is configured 647
