interface (IEEE 802.1ag OAM Connectivity-Fault Management)


Hierarchy Level


For Ethernet interfaces on M320, MX Series, and T Series routers, configure IEEE 802.1ag Operation, Administration, and Management (OAM) support.

For Gigabit Ethernet interfaces and 10-Gigabit Ethernet interfaces on MX Series routers, configure IEEE 802.1ag Connectivity Fault Management (CFM) support on trunk interface ports.

Starting in Junos OS 17.4R1, you can enable support for IEEE 802.1ag CFM on pseudowire service interfaces by configuring maintenance intermediate points (MIPs) on the pseudowire service interfaces.


The CFM MIP session is supported only on the pseudowire services interface and not on the pseudowire services tunnel interface.


interface-name—Interface to which the MEP is attached. It could be a physical Ethernet interface, logical Ethernet interface, pseudowire services interfaces, or on a specific VLAN of a trunk port interface (MX Series only).

Required Privilege Level
