Creating an Aggregate Policer
An aggregate policer is a named policer with an aggregate name that you
can assign to multiple policy maps. You can create either a single-rate or
twin-rate aggregate policer in the Policy Map Configuration mode. There
are three commands that allow you to set the aggregator policer. See
Table 215.
For more information about these commands, see:
 “MLS QOS AGGREGATE-POLICE SINGLE-RATE” on page 1625.
 “MLS QOS AGGREGATE-POLICE TWIN-RATE” on page 1628
 “POLICE AGGREGATE” on page 1649
In the following example, a single-rate aggregate policer, “policyagg1,” is
created with the MLS QOS AGGREGATE-POLICE SINGLE-RATE
command. Within this command, the CIR is 125 Kbps, the CBS is 30,000
bytes, and the EBS is 60,000 bytes. The action is set to policed-dscp-
transmit which modifies packets using the policed-dscp map and then
sends the packets. Then the aggregate policer name is associated with
class maps “cmap1” and “cmap2” with the POLICE AGGREGATE
command:
Table 215. Aggregate Policer Commands
To Do this Task Use this Command
Configures a single-rate policer for a class-
map and create a police aggregator. mls qos aggregate-police
single-rate action
[drop-red|policed-dscp-transmit]
Configures a twin-rate policer for a class-
map. mls qos aggregate-police
twin-rate <
cir>
action [drop-red|policed-dscp-
transmit]
Associates an aggregate name with a class
map. police aggregate name
