Configuring MEP Interfaces

Before you can start an Ethernet frame delay measurement session across an Ethernet service, you must configure two MX Series routers to support ETH-DM.

To configure an Ethernet interface on a DPC in MX Series router to support ETH-DM:

  1. On each router, configure two physical or logical Ethernet interfaces connected by a VLAN. The following configuration is typical for single-tagged logical interfaces:

    [edit interfaces]interface {ethernet-interface-name {vlan-tagging;unit logical-unit-number {vlan-id vlan-id; # Both interfaces on this VLAN}}}
    Both interfaces will use the same VLAN ID.
  2. On each router, attach peer MEPs to the two interfaces. The following configuration is typical:

    [edit protocols]oam {ethernet {connectivity-fault-management {maintenance-domain md-name { # On both routerslevel number;maintenance-association ma-name { # On both routers continuity-check {interval 100ms;hold-interval 1;}mep mep-id { # Attach to VLAN interfaceauto-discovery;direction (up | down);interface interface-name;priority number;}}}}}}
