is disabled, although local critical-event or link fault event is not monitored, failure

indication information from the peer is still normally received and processed.

 Example: Enable remote failure indication of ethernet 1/0/4.

 Switch(Config-If-Ethernet1/0/4)#ethernet-oam remote-failure

8.23 ethernet-oam remote-loopback

 Command: ethernet-oam remote-loopback

 no ethernet-oam remote-loopback

 Function: Local OAM entity sends remote loopback request to enable the remote end

to enter OAM loopback mode, no command disables remote loopback.

 Parameters: None.

 Command Mode: Port mode

 Default: Disable.

 Usage Guide: Only OAM entities working in active mode can launch remote loopback

request but the ones in passive mode cannot. When remote OAM entities work in

loopback mode, all packets except OAMPDU return to the local port according to the

original paths (note that normal communication cannot be performed in OAM loopback

mode.) and network administrators can detect link delay, jitter and throughput through

remote loopback. Remote loopback can only be achieved after OAM connection is

established and the loopback will be automatically cancelled if OAM connection is

disconnected during the loopback process. This command is mutually exclusive with

ethernet-oam remote-loopback supported command.

 Example: Enable remote OAM entity of ethernet 1/0/4 to enter remote loopback

mode.

 Switch(Config-If-Ethernet1/0/4)# ethernet-oam remote-loopback

 Normal forwarding will be suspended during the remote-loopback, are you sure to start

remote-loopback? [Y/N]

8.24 ethernet-oam remote-loopback supported

 Command: ethernet-oam remote-loopback supported

 no ethernet-oam remote-loopback supported

 Function: Enable OAM loopback support of the port, no command disables it.

 Parameters: None.

 Command Mode: Port mode

 Default: Disable.

 Usage Guide: only ports with remote loopback support enabled can accept OAM

loopback request and enter loopback mode. Therefore, make sure the remote end has

configured loopback support when enabling it to enter OAM loopback. This command is

mutually exclusive with ethernet-oam remote-loopback command.

 Example: Enable OAM loopback support of ethernet 1/0/4.
