Description This command is used in ingress and egress queue-group templates to create, modify, or delete a
policer.
Policers are created and used in a similar manner to queues. The policer ID space is separate from the
queue ID space, allowing both a queue and a policer to share the same ID. The ingress queue-group
template have up to 32 policers (numbered 1 through 32) and can be defined while the egress queue-
group template supports a maximum of 8 (numbered 1 through 8). While a policer can be defined in a
queue-group template, it is not actually created until the queue-group template is instantiated on
ingress context of a forwarding plane or on the egress context of a port.
Once a policer is created, the policer's metering rate and profiling rates can be defined as well as the
policer's maximum and committed burst sizes (MBS and CBS respectively). Unlike queues which
have dedicated counters, policers allow various stat-mode settings that define the counters that will be
associated with the policer. Another supported feature—packet-byte-offset—provides a policer with
the ability to modify the size of each packet based on a defined number of bytes.
Once a policer is created, it cannot be deleted from the queue-group template unless any forwarding
classes that are redirected to the policer are first removed.
The no version of this command deletes the policer.
