Persistent. This object is used to administratively disable or
enable the receiver of this port.
If the receiver cannot be selectively disabled by user, this
object is notSupported(1).
If the user wishes to disable this receiver, the user should
set this to outOfService(2). This action should also set the
mib2 object ifAdminStatus to down(2).
If the user wishes to enable this receiver, the user should
set this to inService(3). If nothing else remains disabled,
this should return the mib2 object ifAdminStatus to up(1).
