police aggregate
police aggregate
Use the police aggregate policy-map class configuration command on the switch stack or on a
standalone switch to apply an aggregate policer to multiple classes in 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 remove the specified
policer.
police aggregate aggregate-policer-name
no police aggregate aggregate-policer-name
Syntax Description
Defaults No aggregate policers are defined.
Command Modes Policy-map class configuration
Command History
Usage Guidelines The port ASIC device, which controls more than one physical port, supports 256 policers on the switch
(255 user-configurable policers plus 1 policer reserved for internal use). The maximum number of
configurable policers supported per port is 63. 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 set aggregate policer parameters by using the mls qos aggregate-policer global configuration
command. You apply an aggregate policer to multiple classes in the same policy map; you cannot use an
aggregate policer across different policy maps.
To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode,
use the end command.
You cannot configure aggregate policers in hierarchical policy maps.
Examples This example shows how to define the aggregate policer parameters and to apply the policer to multiple
classes in a policy map:
Switch(config)# mls qos aggregate-policer agg_policer1 10000 1000000 exceed-action drop
Switch(config)# policy-map policy2
Switch(config-pmap)# class class1
Switch(config-pmap-c)# police aggregate agg_policer1
Switch(config-pmap-c)# exit
Switch(config-pmap)# class class2
Switch(config-pmap-c)# set dscp 10
Switch(config-pmap-c)# police aggregate agg_policer1
aggregate-policer-name Name of the aggregate policer.
