Quality of Service Guide
The offered-profile-no-cir mode allocates two forwarding plane offered counters and two
traffic manager discard counters.
The offered-profile-no-cir mode is most useful when profile based offered, discard and
forwarding stats are required from the egress policer, but a CIR is not being used to recolor
the soft in-profile and out-of-profile packets. This mode does not prevent the policer from
being configured with a CIR rate or using exceed PIR.
The counters are used in the following manner:
1. offered-in = soft-in-profile, profile in
2. offered-out = soft-out-of-profile, profile out
3. dropped-in = Same as 1
4. dropped-out = Same as 2
5. forwarded-in = Derived from 1 - 3
6. forwarded-out = Derived from 2 - 4
When collect-stats is enabled, the counters are used by the system to generate the following
statistics:
a. offered-in = 1
b. offered-out = 2
c. discard-in = 3
d. discard-out = 4
e. forward-in (includes forward-exceed that were in) = 5
f. forward-out (includes forward-exceed that were out) = 6
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 profile based offered, discard and
forwarding stats are required from the egress policer and a CIR rate is being used to recolor
the soft in-profile and out-of-profile packets.
The counters are used in the following manner:
1. offered-in-that-stayed-green-or-turned-red
2. offered-soft-that-turned-green
3. offered-soft-or-out-that-turned-yellow-or-red
4. offered-out-that-stayed-yellow-or-turned-red = profile-out
5. dropped-in-that-stayed-green-or-turned-red
6. dropped-soft-that-turned-green
7. dropped-soft-that-turned-yellow-or-red
8. dropped-out-that-stayed-yellow-or-turned-red = Same as 4
9. forwarded-in-that-stayed-green-or-turned-red
10. forwarded-soft-that-turned-green
11. forwarded-soft-or-out-that-turned-yellow-or-turned-red
12. forwarded-out-that-turned-yellow = Derived from 4 - 8
