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):
  user@host> show oam ethernet connectivity-fault-management sla-iterator-statistics sla-iterator i1 maintenance-domain default-1 maintenance-association ma1 local-mep 1 remote-mep 1
