Configuring Routers to Support an ETH-DM Session

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:

Ensuring that Distributed ppm Is Not Disabled on page 754
Enabling the Hardware-Assisted Timestamping Option on page 755
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.
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 routers
level number;
maintenance-association ma-name { # On both routers
continuity-check {
interval 100ms;
hold-interval 1;
}
mep mep-id { # Attach to VLAN interface
auto-discovery;
direction (up | down);
interface interface-name;
priority number;
}
}
}
}
}
}
