Service Egress and Ingress QoS Policies
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 = 5
f. forward-out = 6
With offered-profile-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-in = 1
ii. offered-out = 2
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-priority-no-cir — Counter resource allocation: 2
The offered-priority-no-cir mode allocates two forwarding plane offered counters and two
traffic manager discard counters.
The offered-priority-no-cir mode is most useful when the policer is receiving only untrusted
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 premarked 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 = profile in, priority high
2. offered-low = profile out, priority low
3. dropped-high = Same as 1
4. dropped-low = Same as 2
5. forwarded-high = Derived from 1 - 3
6. forwarded-low = Derived from 2 - 4
When collect-stats is enabled, the counters are used by the system to generate the following
statistics:
a. offered-high = 1
b. offered-low = 2
c. discard-high = 3
d. discard-low = 4
e. forward-high = 5
f. forward-low = 6
