Description | This table contains controls for the loopback state of the
local link as well as indicating the status of the loopback
function. There is one entry in this table for each entry in
cdot3OamTable that supports loopback functionality (where
cdot3OamFunctionsSupported includes the loopbackSupport bit
set).
Loopback can be used to place the remote OAM entity in a state
where every received frame (except OAMPDUs) is echoed back
over the same interface on which they were received. In this
state, at the remote entity, 'normal' traffic is disabled as
only the looped back frames are transmitted on the interface.
Loopback is thus an intrusive operation that prohibits normal
data flow and should be used accordingly. |
