Junos OS for EX Series switches allows the Ethernet interfaces on these switches to
support the IEEE 802.3ah standard for the Operation, Administration, and Maintenance
(OAM) of Ethernet in access networks. The standard defines OAM link fault management
(LFM). You can configure IEEE 802.3ah OAM LFM on point-to-point Ethernet links that
are connected either directly or through Ethernet repeaters.
This example describes how to enable and configure OAM LFM on a Gigabit Ethernet
interface:

This example uses the following hardware and software components:
Junos OS Release 9.4 or later for EX Series switches
Two EX3200 or EX4200 switches connected directly
Overview and Topology
Junos OS for EX Series switches allows the Ethernet interfaces on these switches to
support the IEEE 802.3ah standard for the Operation, Administration, and Maintenance
(OAM) of Ethernet in access networks. The standard defines OAM link fault management
(LFM). You can configure IEEE 802.3ah OAM LFM on point-to-point Ethernet links that
are connected either directly or through Ethernet repeaters.
This example uses two EX4200 switches connected directly. Before you begin configuring
Ethernet OAM LFM on two switches, connect the two switches directly through a trunk
interface.
Configuring Ethernet OAM Link Fault Management on Switch 1
To quickly configure Ethernet OAM LFM, copy the following commands and paste them
into the switch terminal window:
[edit protocols oam ethernet link-fault-management]
set interface ge-0/0/0
set interface ge-0/0/0 link-discovery active
set interface ge-0/0/0 pdu-interval 800
set interface ge-0/0/0 remote-loopback
To configure Ethernet OAM LFM on switch 1:
Enable IEEE 802.3ah OAM support on an interface:
1.
[edit protocols oam ethernet link-fault-management]
user@switch1# set interface ge-0/0/0
