All packets received on the egress forwarding plane are 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.
Egress policers have a default CIR set to 0, but in the egress case a value of 0 disables policer profiling. Egress packets on a CIR-disabled egress policer retain their offered profile state (soft-in-profile, soft-out-of-profile, hard-inplus, hard-in-profile, hard-out-of-profile, or hard-exceed-profile) unless the enable-exceed-pir command is configured, in which case the exceed-profile state of a packet takes precedence over the hard-out/in/inplus reclassification.
For egress, the possible types of offered packets include:
soft offered in-profile (from ingress)
soft offered out-of-profile (from ingress)
egress explicit inplus-profile (reclassified at egress)
egress explicit in-profile (reclassified at egress)
egress explicit out-of-profile (reclassified at egress)
egress explicit exceed-profile (reclassified at egress)
The possible output results are:
output inplus-profile
output in-profile
output out-of-profile
output discard or exceed-profile
The stat-mode command follows the same counter resource rules as ingress.
Egress supported stat-modes are:
no-stats
minimal - default
offered-profile-no-cir
offered-profile-cir
offered-total-cir
offered-limited-capped-cir
offered-profile-capped-cir
offered-total-cir-exceed
offered-four-profile-no-cir
offered-total-cir-four-profile
Details of the output showing the stat-modes for ingress and egress child policers are in the Class Fair Hierarchical Policing for SAPs section of the SR OS Advanced Configuration Guide.
