Policer Interaction with Initial Profile, Discard Eligibility, and Ingress Priority
866 Quality of Service Guide
Third, when the policer has a CIR = 0 rate (the default rate), all profile capped packets are
treated as out-of-profile independent of the initial profile state.
Forwarding Traffic Exceeding PIR in Egress Policers
An egress policer can be configured to forward traffic which exceeds its oper PIR instead of
dropping it. The traffic exceeding the PIR is assigned an exceed profile state. This is
supported for any configured (not dynamic) policer in a SAP egress QoS policy, which can
be used for both SAPs and subscribers, and in an egress queue group template which can be
used on egress network ports.
This is configured using the enable-exceed-pir command and the stat-mode offered-total-
cir-exceed provides forward and drop counters for exceed profile traffic, as shown below

The dot1p, outer dot1p, DSCP and precedence can be remarked for the exceed profile traffic.
Ingress Child Policer Stat-Mode
A policer has multiple types of input traffic and multiple possible output states for each input
traffic type. These variations differ between ingress and egress.
