To start a proactive Ethernet synthetic loss measurement (ETH-SLM) session, you must
configure the Ethernet interfaces on maintenance association end points (MEPs) on
which packets transmitted with synthetic frame loss need to be analyzed. You must then
create an iterator profile to transmit service-level agreement (SLA) measurement packets
for ETH-SLM and associate the local and remote MEPs with the profile.

Before you can start an Ethernet synthetic frame loss measurement session across an
Ethernet service, you must configure two ACX Series routers to support ETH-SLM.
To configure an Ethernet interface on an ACX Series router to support ETH-SLM:
On each router, configure two physical or logical Ethernet interfaces connected by a
1.
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
2.
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;
