Service SAP QoS Policy Command Reference
272 Quality of Service Guide
The offered-priority-cir mode is most useful when the policer is receiving only untrusted
packets that are being classified as high priority or low priority and are being applied to a
defined CIR profiling rate. This mode differs from offered-profile-cir mode in that it does
not expect trusted in-profile and out-of-profile packets but does not exclude the ability of the
policer to receive them.
The counters are used in the following manner:
1. offered-high-that-turned-green = profile in, priority high
2. offered-high-that-turned-yellow-or-red = profile in, priority high
3. offered-low-that-turned-green = profile out, priority low
4. offered-low-that-turned-yellow-or-red = profile out, priority low
5. dropped-high-that-turned-green = Same as 1
6. dropped-high-that-turned-yellow-or-red = Same as 2
7. dropped-low-that-turned-green = Same as 3
8. dropped-low-that-turned-yellow-or-red = Same as 4
9. forwarded-high-that-turned-green = Derived from 1 - 5
10. forwarded-high-that-turned-yellow = Derived from 2 - 6
11. forwarded-low-that-turned-green = Derived from 3 - 7
12. forwarded-low-that-turned-yellow = Derived from 4 - 8
When collect-stats is enabled, the counters are used by the system to generate the following
statistics:
a. offered-high = 1 + 2
b. offered-low = 3 + 4
c. discard-in = 5 + 7
d. discard-out = 6 + 8
e. forward-in = 9 + 11
f. forward-out = 10 + 12
With offered-priority-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 = 1 + 2
ii. offered-low = 3 + 4
iii. offered-undefined = 0
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-total-cir — Counter resource allocation: 2
The offered-total-cir mode allocates two forwarding plane offered counters and two traffic
manager discard counters.
The offered-total-cir mode is most useful when the policer is not receiving trusted in-profile
or out-of-profile traffic and both high and low priority classifications are not being used on
the untrusted packets and the offered packets are being applied to a defined CIR profiling rate.
This mode does not prevent the policer from receiving trusted in-profile or out-of-profile
packets and does not prevent the use of priority high or low classifications on the untrusted
packets.
