Service Ingress QoS Policy Commands
The policer does not have any forwarding plane counters allocated and cannot provide offered, discard
and forward statistics. A policer using no-stats cannot be a child to a parent policer and the policer's
parent command will fail.
When collect-stats is enabled, the lack of counters causes the system to generate the following
statistics:
a. offered-in
b. offered-out
c.'discard-in
d. discard-out
e. forward-in
f. forward-out
Counter 0 indicates that the accounting statistic returns a value of zero.
minimal — Counter resource allocation:1
The default stat-mode for a policer is minimal. The minimal mode allocates 1 forwarding plane
offered counter and one traffic manager discard counter. The forwarding counter is derived by
subtracting the discard counter from the offered counter. The counters do not differentiate possible
offered types (profile or priority) and do not count green or yellow output. This does not prevent the
policer from supporting different offered packet types and does not prevent the policer from supporting
a CIR rate.
This counter mode is useful when only the most basic accounting information is required.
The counters are used in the following manner:
1. offered
2. discarded
3. forwarded
When collect-stats is enabled, the counters are used by the system to generate the following statistics:
a. offered-in
b. offered-out
c. discard-in
d. discard-out
e. forward-in
f. forward-out
Counter 0 indicates that the accounting statistic returns a value of zero.
With minimal 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
ii. offered-out
