Understanding Ethernet OAM Connectivity Fault Management for an EX Series Switch
Ethernet interfaces on Juniper Networks EX Series Ethernet Switches and Juniper Networks
Junos operating system (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). CFM monitors
Ethernet networks that might comprise one or more service instances for
network-compromising connectivity faults.
The major features of CFM are:
•
Fault monitoring using the continuity check protocol. This is a neighbor discovery and
health check protocol that discovers and maintains adjacencies at the VLAN or link
level.
•
Path discovery and fault verification using the linktrace protocol.
•
Fault isolation using the loopback protocol.
CFM partitions the service network into various administrative domains. For example,
operators, providers, and customers might be part of different administrative domains.
Each administrative domain is mapped into one maintenance domain providing enough
information to perform its own management, thus avoiding security breaches and making
end-to-end monitoring possible.
