Configuring Ethernet 802.1ag OAM on PTX Series Packet Transport Routers

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 Routers.

Supported features include:

  • Maintenance domain (maintenance-domain domain-name) and maintenance levels (level number).
  • Maintenance association (maintenance-association ma-name), including name formats (name-format and short-name-format for vlan and 2octet), loss threshold (loss-threshold number), and hold interval (hold-interval minutes).
  • maintenance association endpoint (MEP) functions, including Maintenance Endpoint ID (mep mep-id), direction down (direction down), and autodiscovery (auto-discovery).
  • Link trace for down MEPs (link-down).
  • action profile (action-profile profile-name)
  • Loopback message generation and reply for down MEPs.

Features that are not supported include:

  • Up MEP configuration.
  • maintenance association intermediate point (MIP) configuration.

To configure flexible Ethernet services encapsulation on PTX Series Packet Transport Routers, include the oam statement at the [edit protocols] hierarchy level. For example:

[edit protocols]
oam {ethernet {connectivity-fault-management {maintenance-domain md1 {level 0;maintenance-association ma1 {continuity-check {interval 100ms;}mep 1 {interface et-0/1/1;direction down;auto-discovery;}}}}}}
