Displaying And Maintaining Ethernet Oam Configuration - H3C S9500E Series Configuration Manual

To do...
1. Enter system view
2. Enter Ethernet port view
3. Enable Ethernet OAM remote
loopback
Ethernet OAM remote loopback is available only after the Ethernet OAM connection is established, and
•
it can be performed only by 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 must be supported by the remote port as well as the sending port.
•
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
o
Executing the undo oam loopback command to disable Ethernet OAM remote
o
loopback
The Ethernet OAM connection timing out
o
Ethernet OAM remote loopback is only applicable to individual links. It is not applicable to link
•
aggregation member ports. In addition, you cannot assign ports where Ethernet OAM remote loopback
is being performed to link aggregation groups.
Enabling internal loopback test on a port in remote loopback test can terminate the remote loopback
•
test. For more information about loopback testing, see Ethernet Interface in the Layer 2 – LAN Switching
Configuration Guide.
