Example: Configuring Ethernet OAM Connectivity Fault Management on EX Series Switches
Ethernet interfaces on Juniper Networks EX Series Ethernet Switches and Juniper Networks
Junos OS for EX Series switches support the IEEE 802.1ag standard for Operation,
Administration, and Management (OAM). The IEEE 802.1ag specification provides for
Ethernet connectivity fault management (CFM).
This example describes how to enable and configure OAM CFM on a Gigabit Ethernet
interface:

• Configuring Ethernet OAM Connectivity Fault Management on Switch 2 on page 3766
• Verification on page 3767
Requirements
This example uses the following hardware and software components:
• Junos OS Release 10.2 or later for EX Series switches
•
Two EX Series switches connected by a point-to-point Gigabit Ethernet link
Overview and Topology
CFM can be used to monitor the physical link between two switches. In the following
example, two switches are connected by a point-to-point Gigabit Ethernet link. The link
between these two switches is monitored using CFM.
Configuring Ethernet OAM Connectivity Fault Management on Switch 1
CLI Quick
Configuration
To quickly configure Ethernet OAM CFM, copy the following commands and paste them
into the switch terminal window:
[edit protocols oam ethernet connectivity-fault-management maintenance-domain ]
set name-format character-string
set maintenance-domain private level 0
set maintenance-association private-ma
set continuity-check hold-interval 1s
Step-by-Step
Procedure
To enable and configure OAM CFM on switch 1:
1.
Specify the maintenance domain name format:
[edit protocols oam ethernet connectivity-fault-management
maintenance-domain ]
user@switch1# set name-format character-string
2.
Specify the maintenance domain name and the maintenance domain level:
[edit protocols oam ethernet connectivity-fault-management]
user@switch1#
set maintenance-domain private level 0
3.
Create a maintenance association:
