Managing Iterator Statistics
Displaying Iterator Statistics
Purpose
Retrieve and display iterator statistics.
Muliple iterators can be associated with a remote MEP. However, by default, only one result pertaining to one iterator profile is displayed.
Action
- To display the iterator statistics for remote MEP 1 and iterator profile i1 with MEPs belonging to the
maintenance association ma1 and within the maintenance
domain default-1 (here, the iterator profile i1 is
configured for two-way delay measurement):

association ma1 and within the maintenance domain default-1:
user@host> clear oam ethernet connectivity-fault-management sla-iterator-statistics sla-iterator i1 maintenance-domain default-1 maintenance-association ma1 local-mep 1 remote-mep 1 - To clear the iterator statistics for remote MEP 1 and iterator profile i2 with MEPs belonging to the maintenance
