Table 3: Monitor Ethernet Delay Command Parameters (continued)
DescriptionParameter RangeParameter
(Optional) Specifies the number of seconds to wait between frames. The
default is 1 second.
1–255 seconds

If you attempt to monitor delays to a nonexistent MAC address, you must exit the
application manually using ^C:
user@host> monitor ethernet delay-measurement two-way 00:11:22:33:44:55
Two-way ETH-DM request to 00:11:22:33:44:55, Interface ge-5/2/9.0

Viewing Ethernet Frame Delay Measurements Statistics
Once Ethernet frame delay measurement statistics have been collected, they can be
displayed.
To retrieve the last 100 Ethernet frame delay measurement statistics per remote MEP
or per CFM session, two types of show commands are provided:
•
For all OAM frame counters and Ethernet frame delay measurement statistics
•
For Ethernet frame delay measurement statistics only
To retrieve all Ethernet frame delay measurement statistics for a given session, use the
show oam ethernet connectivity-fault-management mep-statistics maintenance-domain
name maintenance-association name [local-mep identifier] [remote-mep identifier] [count
count] command.
To retrieve only Ethernet frame delay measurement statistics for a given session, use
the show oam ethernet connectivity-fault-management delay-statistics
maintenance-domain name maintenance-association name [local-mep identifier]
[remote-mep identifier] [count count] command.
