Note: As a requirement for Ethernet OAM 802.1ag to work, you must enable distributed periodic packet management (PPM) by including the delegate-processing statement at the [edit routing-options ppm] hierarchy level. |
Ethernet interfaces on M120, M320, MX-series, and T-series routing platforms support the IEEE 802.1ag standard for Operation, Administration, and Management (OAM). The IEEE 802.1ag specification provides for Ethernet connectivity-fault management (CFM). The goal of CFM is to monitor an Ethernet network that may comprise one or more service instances. JUNOS software supports IEEE 802.1ag connectivity fault management.
Network entities such as operators, providers, and customers may be part of different administrative domains. Each administrative domain is mapped into one maintenance domain. Maintenance domains are configured with different level values to keep them separate. Each domain provides enough information for the entities to perform their own management, perform end-to-end monitoring, and still avoid security breaches.

IEEE 802.1ag OAM supports graceful Routing Engine switchover. IEEE 802.1ag OAM is supported on untagged, single tagged, and stacked VLAN interfaces.
