On PTX Series Packet Transport Switches, Junos OS Release 12.1 supports the following
IEEE 802.3ah OAM features at the physical interface level:
• Discovery and link monitoring
• Fault signaling and detection
• Periodic packet management (PPM) processing
• Action profile support
• graceful Routing Engine switchover (GRES)
To configure 802.3ah OAM support for Ethernet interfaces, include the oam statement
at the [edit protocols] hierarchy level:
•
oam {
ethernet {
link-fault-management {
interfaces {
interface-name {
pdu-interval interval;
link-discovery (active | passive);
pdu-threshold count;
}
}
}
}
}

Configuring Ethernet 802.1ag OAM on PTX Series Packet Transport Switches
Copyright © 2012, Juniper Networks, Inc.
The IEEE 802.1ag provides a specification for Ethernet connectivity fault management
(CFM). The Ethernet network may be comprised of one or more service instances. A
service instance could be a VLAN, or a concatenation of VLANs. The goal of CFM is to
provide a mechanism to monitor, locate, and isolate faulty links. Ethernet 802.1ag is
supported on numerous Juniper Networks routers and switches. This topic describes
configuration support for Ethernet OAM 802.1ag features on the PTX Series Packet
Transport Switches.
