This object configures an endpoint in loopback:

This is a mandatory object.

* To configure a destructive loopback, this object needs to be set to destructive (2). The direction in which this destructive loopback needs to be effected, should be specified using the cwaChanTestDir object. To de-configure destructive loopback, this object needs to be set to noLpbk(1). * To configure a non-destructive loopback, this object needs to be set to nonDestructive(3). The direction in which this non-destructive loopback needs to be effected, should be specified using the cwaChanTestDir object. Non-destructive loopback gets de-configured automatically at the switch after a certain timeout. However, if there is a need to abort a non-destructive loopback, a set operation on this object should be performed with a value noLpbk (1). * Attempting to set a channel in loopback, when one is already in progress results in a failure of the set operation (with appropriate error code)
