mls qos aggregate-policer
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.

Command History
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.
aggregate-policer-name
Name of the aggregate policer referenced by the
police aggregate
policy-map class configuration command.
rate-bps
Specify the average traffic rate in bits per second (bps). The range
is 8000 to 1000000000.
burst-byte
Specify the normal burst size in bytes. The range is 8000 to 1000000.
exceed-action drop
When the specified rate is exceeded, specify that the switch drop the
packet.
exceed-action
policed-dscp-transmit
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.
