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= profile in, priority high/low
2. offered-undefined-that-turned-yellow-or-red= priority high/low
3. offered-out-that-stayed-yellow-or-turned-red= profile out
4. dropped-undefined-that-turned-green= Same as 1
5. dropped-undefined-that-turned-yellow-or-red= Same as 2
6. dropped-out-that-turned-yellow-or-red= Same as 3
7. forwarded-undefined-that-turned-green= Derived from 1 - 4
8. forwarded-undefined-that-turned-yellow= Derived from 2 - 5
9. forwarded-out-that-turned-yellow= Derived from 3 - 6
When collect-stats is enabled, the counters are used by the system to generate the following statistics:
a. offered-in = 0
b. offered-out= 1 + 2 + 3
c. discard-in = 0
d. discard-out= 4 + 5 + 6
e. forward-in = 7
f. 'orward-out= 8 + 9
With offered-limited-profile-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-in = 0
ii.'offered-out= 3
iii.'offered-undefined= 1 + 2
iv. offered-managed= 0(IMPM managed packets are not redirected from the policer)
Counter 0 indicates that the SAP policer statistic returns a value of zero.
offered-profile-cir — Counter resource allocation:4
The offered-profile-cir mode allocates four forwarding plane offered counters and four traffic manager
discard counters.
The offered-profile-cir mode is most useful when the policer is receiving trusted out-of-profile and in-
profile traffic and is also receiving un-trusted packets that are being applied to a defined CIR profiling
rate. This mode differs from offered-limited-profile-cir mode in that it expects both trusted in-profile
and out-of-profile packets while still performing CIR profiling on packets with un-trusted markings. It
