QoS Commands

qos aggregate-policer

The qos aggregate-policer Global Configuration mode command defines the policer parameters
that can be applied to multiple traffic classes within the same policy map. To remove an existing
aggregate policer, use the no form of this command.
Syntax
qos aggregate-policer aggregate-policer-name committed-rate-bps excess-burst-byte
exceed-action {drop | policed-dscp-transmit} [dscp dscp]
no qos aggregate-policer
Parameters
■
aggregate-policer-name — Specifies the name of the aggregate policer.
■
committed-rate-bps — Specifies the average traffic rate (CIR) in bits per second (bps).
■
excess-burst-byte — Specifies the normal burst size (CBS) in bytes.
■
drop — Indicates that when the rate is exceeded, the packet is dropped.
■
policed-dscp-transmit — Indicates that when the rate is exceeded, the DSCP of the packet
is remarked.
■
dscp — Specifies the value that the DSCP would be remarked. If unspecified, the DSCP
would be remarked according to the policed-DSCP map as configured by the qos map
policed-dscp Global Configuration mode command.
Default Setting
No aggregate policer is define.
Command Mode
Global Configuration mode
Command Usage
Define an aggregate policer if the policer is shared with multiple classes.
Policers in one port cannot be shared with other policers in another device; traffic from two
different ports can be aggregated for policing purposes.
An aggregate policer can be applied to multiple classes in the same policy map; An aggregate
policer cannot be applied across multiple policy maps.
An aggregate policer cannot be deleted if it is being used in a policy map. The no police
aggregate Policy-map Class Configuration command must first be used to delete the aggregate
policer from all policy maps.
Policing uses a token bucket algorithm. CIR represents the speed with which the token is
removed from the bucket. CBS represents the depth of the bucket.
Example
The following command defines the parameters of an aggregate policer called policer1 that can
be applied to multiple classes in the same policy map. When the average traffic rate exceeds
124,000 bps or the normal burst size exceeds 96000 bytes, the packet is dropped.
Console (config)# qos aggregate-policer policer1 124000 96000 exceed-action drop
