Service Ingress QoS Policy Commands
The offered-priority-no-cir mode is most useful when the policer is receiving only un-trusted packets
and the ingress priority high and priority low classification options are being used without a CIR
profiling rate defined. This mode does not prevent the policer from receiving trusted packets that are
pre-marked in-profile or out-of-profile nor does it prevent the policer from being configured with a CIR
rate.
The counters are used in the following manner:
1. offered-high
2. offered-low
3. dropped-high
4. dropped-low
5. forwarded-high
6. forwarded-low
When collect-stats is enabled, the counters are used by the system to generate the following statistics:
a. offered-high
b. offered-low
c. discard-high
d. discard-low
e. forward-high
f. forward-low
With offered-priority-no-cir enabled as the policer stat-mode, the SAP offered stats for the policer
returned via MIB query and CLI show commands will return the following values:
i. offered-high
ii. offered-low
iii. offered-undefined
iv. offered-managed
Counter 0 indicates that the SAP policer statistic returns a value of zero.
offered-limited-profile-cir — Counter resource allocation:3
The offered-limitied-profile-cir mode allocates three forwarding plane offered counters and three
traffic manager discard counters.
The offered-limited-profile-cir mode is most useful when the policer is receiving trusted out-of-profile
(profile out but no profile in) traffic and un-trusted packets are being applied to a defined CIR profiling
rate. This mode does not prevent the policer from receiving trusted in-profile packets.
The counters are used in the following manner:
1. offered-undefined-that-turned-green
2. offered-undefined-that-turned-yellow-or-red
3. offered-out-that-stayed-yellow-or-turned-red = profile out
