NOTE:
Ethernet OAM remote loopback is available only after the Ethernet OAM connection is established and can be
performed only by the Ethernet OAM entities operating in active Ethernet OAM mode.
Remote loopback is available only on full-duplex links that support remote loopback at both ends.
Ethernet OAM remote loopback needs the support of the peer hardware.
Enabling Ethernet OAM remote loopback interrupts data communications. After Ethernet OAM remote loopback
is disabled, all the ports involved will shut down and then come up. Ethernet OAM remote loopback is disabled
by any of the following actions: executing the undo oam enable command to disable Ethernet OAM; executing
the undo oam loopback command to disable Ethernet OAM remote loopback; timeout of the Ethernet OAM
connection.
Ethernet OAM remote loopback is only applicable to individual links. It is not applicable to link aggregation
member ports. In addition, do not assign ports where Ethernet OAM remote loopback is being performed to link
aggregation groups. For more information about link aggregation groups, see the
Configuration Guide
Enabling internal loopback test on a port in remote loopback test can terminate the remote loopback test. For
more information about loopback test, see the
Rejecting the Ethernet OAM remote loopback request from a
remote port
The Ethernet OAM remote loopback function impacts other services. To solve this problem, you can
disable a port from being controlled by the Loopback Control OAMPDUs sent by a remote port. The local
port then rejects the Ethernet OAM remote loopback request from the remote port.
Follow these steps to reject the Ethernet OAM remote loopback request from a remote port:
To do...
Enter system view
Enter Layer 2 Ethernet port view
Reject the Ethernet OAM remote
loopback request from a remote
port
Displaying and maintaining Ethernet OAM
configuration
To do...
Display global Ethernet OAM
configuration
Display the statistics on critical
events after an Ethernet OAM
connection is established
.
