Since OAM loopback is a distruptive operation (user traffic
does not pass), this attribute provides a mechanism to provide
controls over whether received OAM loopback commands are
processed or ignored. When the value is ignore(1), received
loopback commands are ignored. When the value is process(2),
OAM loopback commands are processed. The default value is to
ignore loopback commands (ignore(1)).
The attribute has no meaning if the local OAM entity does not
support the loopback function (as defined in
h3cDot3OamFunctionsSupported).
