Configuring ATM F5-OAM End-to-End Loopback

A Passport 8672ATME Module, by default, replies to ATM F5-OAM Loopback requests received. However, the transmission of F5-OAM Loopback requests and the processing of F5-OAM Loopback replies received require enabling this feature on a PVC by PVC basis. It is recommended that you enable ATM

F5-OAM on all the PVCs configured on the PP8672 ATM port, in order for upper layer protocols such as MLT and OSPF to be immediately aware of the port down status or link failures.

You can configure the ATM F5-OAM End-to-End Loopback parameters with Device Manager or the CLI. For information on how to configure this feature with the CLI, see “Managing the Passport 8672ATME Module with the CLI” on page 75.
