Displaying And Maintaining Ethernet Oam Configuration - 3Com S7906E Configuration Manual

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 when you execute the undo oam enable command to disable
Ethernet OAM, when you execute the undo oam loopback command to disable Ethernet OAM
remote loopback, or when the Ethernet OAM connection times out.
Ethernet OAM remote loopback is only applicable to individual links. It is not applicable to link
aggregation member ports or service loopback group member ports. In addition, you cannot assign
ports where Ethernet OAM remote loopback is being performed to link aggregation groups or
service loopback groups. For more information about link aggregation groups and service loopback
groups, refer to Link Aggregation Configuration and Service Loopback Group Configuration in the
Access Volume.
Enabling internal loopback test on a port in remote loopback test can terminate the remote
loopback test. For more information about loopback test, refer to Ethernet Interface Configuration
in the Access Volume.
