Loopback Mode Detection Through OAM
The Loopback Mode Detection Through OAM feature allows you to enable automatic detection of when
a peer ATM interface is in loopback mode. When loopback is detected on an interface where end-to-end
F5 Operation, Administration, and Maintenance (OAM) is enabled, the impacted permanent virtual
circuit (PVC) is moved to a DOWN state, and traffic is suspended. When the loopback condition in the
peer ATM interface is removed, the PVC is moved back to an UP state.
