Make sure to use the correct stat-mode if the policer's CIR is explicitly not set or is set to 0.

The no-cir version of the stat-mode must be used and when the CIR has a non-zero value.

Also when overriding the policer's cir mode, make sure you override the stat-mode instance

(cir override can be performed using snmp access).

Ingress supported stat-modes are:

Egress Child Policer Stat-Mode

Egress policers have fewer stat-mode options due to the fact that they do not deal with offered

packets with an undefined profile state. All packets received on the egress forwarding plane

have been profiled as either in-profile or out-of-profile. The egress forwarding plane treats

the ingress derived profile as a soft state that may be either overridden by an egress profile

reclassification or by a CIR rate enforced by an egress policer.

For egress, the possible types of offered packets include:

Similar to ingress, the possible output results are:

The stat-mode command follows the same counter resource rules as ingress.
