3 In the
Ethernet loopback admin
field, select
Enable
to enable Ethernet
loopback on the logical interface, or
Disable
to disable Ethernet loopback on
the logical interface.
4 In the
Ethernet loopback duration (sec)
field, enter the loopback duration
time (in seconds).
5 In the
Swap MAC address admin
field, select whether to swap DA and SA MAC
addresses during the loopback. Swapping addresses prevents Ethernet loops
from occurring. It is recommended to enable MAC address swapping if LLDP is
enabled.
6 Click
Apply
to initiate the loopback.

SOAM Overview
The Y.1731 standard and the MEF-30 specifications define Service OAM (SOAM).
SOAM is concerned with detecting, isolating, and reporting connectivity faults
spanning networks comprising multiple LANs, including LANs other than IEEE
802.3 media.
Y.1731 Ethernet FM (Fault Management) consists of three protocols that operate
together to aid in fault management:
•
Continuity check
•
Link trace
•
Loopback
Note:
Link trace is planned for future release.
IP-20 utilizes these protocols to maintain smooth system operation and non-stop
data flow.
The following are the basic building blocks of FM:
•
MD (Maintenance Domain)
–
An MD defines the management space on a
network, typically owned and operated by a single entity, for which
connectivity faults are managed via SOAM.
•
MA/MEG (Maintenance Association/Maintenance Entity Group)
–
An
MA/MEG contains a set of MEPs or MIPs.
