What is slTestsTrapsLoopbackActive?

This is a notification-carried value indicating whether a loopback is currently active on the device. Admins use it, in traps, to be immediately alerted whenever a loopback test starts or is active, since a loopback in progress affects normal traffic on that interface. A trap with slTestsTrapsLoopbackActive of true would alert an admin that a port has entered loopback mode, which they should be aware could be interrupting normal service on that link.
