tem-resources command. If insufficient counters exist to implement a mode on any policer instance, the
stat-mode change will fail and the previous mode will continue unaffected for all instances of the policer.
The default stat-mode when a policer is created within the policy is minimal.
The stat-mode setting defined for the policer in the QoS policy may be overridden on an sla-profile or SAP
where the policy is applied. If insufficient policer counter resources exist to implement the override, the
stat-mode override command will fail. The previous stat-mode setting active for the policer will continue
to be used by the policer.
The no form of this command attempts to return the policer's stat-mode setting to minimal. The command
will fail if insufficient policer counter resources exist to implement minimal where the QoS policer is cur-
rently applied and has a forwarding class mapping.
Parameters no-stats — Counter resource allocation:0
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 = 0
b. offered-out = 0
c. discard-in = 0
d. discard-out = 0
e. forward-in = 0
f. forward-out= 0
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 = Same as 1
3. 'forwarded = Derived from 1 - 2
When collect-stats is enabled, the counters are used by the system to generate the following statistics:
a. offered-in = 1
b. offered-out= 0
