Configuring a Remote Loop Back Test
Use the Administration > OAM > Remote Loopback (Remote Loopback Test) page to initiate a loop
back test to the peer device attached to the selected port.

“efm oam remote-loopback test”
Command Usage
•
You can use this command to perform an OAM remote loop back test on the specified port. The
port that you specify to run this test must be connected to a peer OAM device capable of
entering into OAM remote loop back mode.
•
During a remote loop back test, the remote OAM entity loops back every frame except for
OAMPDUs and pause frames.
•
OAM remote loopback can be used for fault localization and link performance testing.
Statistics from both the local and remote DTE can be queried and compared at any time during
loop back testing.
•
To perform a loopback test, first enable Remote Loop Back Mode, click Test, and then click
End. The number of packets transmitted and received will be displayed.
Parameters
These parameters are displayed:
Loopback Mode of Remote Device
•
Port – Port identifier. (Range: 1-12)
•
Loopback Mode – Shows if loopback mode is enabled on the peer. This attribute must be
enabled before starting the loopback test.
•
Loopback Status – Shows if loopback testing is currently running.
Loopback Test Parameters
•
Packet Number – Number of packets to send. (Range: 1-99999999; Default: 10000)
•
Packet Size – Size of packets to send. (Range: 64-1518 bytes; Default: 64 bytes)
•
Test – Starts the loop back test.
•
End – Stops the loop back test.
Loop Back Status of Remote Device
•
Result – Shows the loop back status on the peer. The loop back states shown in this field are
described below.
TABLE 181
Remote Loopback Status
State
Description
No Loopback
Operating in normal mode with no loopback in progress.
Initiating Loopback
The local OAM entity is starting the loopback process with its peer. It has yet to
receive any acknowledgement that the remote OAM entity has received its
loopback command request.
Remote Loopback
The local OAM client knows that the remote OAM entity is in loopback mode.
