mls qos aggregate-policer Chapter 2 Catalyst 3560 Switch Cisco IOS Commands mls qos aggregate-policer Use the mls qos aggregate-policer global configuration command to define policer parameters, which can be shared by multiple classes within the same policy map. A policer defines a maximum permissible rate of transmission, a maximum burst size for transmissions, and an action to take if either maximum is exceeded. Use the no form of this command to delete an aggregate policer. mls qos aggregate-policer aggregate-policer-name rate-bps burst-byte exceed-action {drop | policed-dscp-transmit} no mls qos aggregate-policer aggregate-policer-name Syntax Description aggregate-policer-name rate-bps burst-byte exceed-action drop exceed-action policed-dscp-transmit Name of the aggregate policer referenced by the police aggregate policy-map class configuration command. Specify the average traffic rate in bits per second (bps). The range is 8000 to 1000000000. Specify the normal burst size in bytes. The range is 8000 to 1000000. When the specified rate is exceeded, specify that the switch drop the packet. When the specified rate is exceeded, specify that the switch change the Differentiated Services Code Point (DSCP) of the packet to that specified in the policed-DSCP map and then send the packet. Defaults No aggregate policers are defined. Command Modes Global configuration Command History Release 12.1(19)EA1 Modification This command was introduced. Usage Guidelines Define an aggregate policer if the policer is shared with multiple classes. Policers for a port cannot be shared with other policers for another port; traffic from two different ports cannot be aggregated for policing purposes. The port ASIC device, which controls more than one physical port, supports 256 policers (255 policers plus 1 no policer). The maximum number of policers supported per port is 64. Policers are allocated on demand by the software and are constrained by the hardware and ASIC boundaries. You cannot reserve policers per port (there is no guarantee that a port will be assigned to any policer). You apply an aggregate policer to multiple classes in the same policy map; you cannot use an aggregate policer across different policy maps. 2-240 Catalyst 3560 Switch Command Reference 78-16405-05
