Release Information

Statement introduced in Junos OS Release 17.4R1 for PTX Series routers.


Configure the device to allow LACP, LLDP, OAM LFM, and OAM CFM packets to cross the Layer 2 circuit. If the l2circuit-control-passthrough statement is not configured, LACP, LLDP, OAM LFM, and OAM CFM packets are classified as control packets and are not transmitted across the Layer 2 circuit.


For MX Series routers, the functionality that the l2circuit-control-passthrough command provides is performed automatically.


By default, this statement is not configured.
