testing
Note:
OAM loopback testing is available only after the OAM connection is established.
OAM loopback testing can be performed by OAM entities operating in the active
OAM mode only.
OAM loopback testing is available only on full-duplex links.
OAM loopback testing needs the support of the peer hardware.
OAM loopback testing is only applicable to individual links. It is not applicable to
aggregation links. So when performing OAM loopback testing, make sure none of
the ports involved belongs to an aggregation group.
Enabling OAM loopback testing results in all the data communications being
stopped. After OAM loopback testing is disabled, all the ports involved will be shut
down and then brought up.
OAM loopback testing is disabled when you execute the undo oam enable
command to disable OAM; when you execute the undo oam loopback command
to disable OAM loopback testing; or when the OAM connection is timed out.
