Example: Configuring Ethernet LFM for Aggregated Ethernet

In this example, LFM is configured on an aggregated Ethernet interface (AE0) between Router 1 and Router 2. When configured on aggregated Ethernet, LFM runs on all the individual member links. LFM is enabled or disabled on the member links as they are added or deleted from the aggregation group. The status of individual links is used to determine the status of the aggregated interface.

The use of LFM with aggregated Ethernet is shown in Figure 1.

1. Configure LFM on Router 1 for AE0:

   [edit]chassis {aggregated-devices {ethernet {device-count 1;}}}interfaces ge-1/0/1 {gigether-options {802.3ad ae0;}}interfaces ge-2/0/0 {gigether-options {802.3ad ae0;}}interfaces ae0 {unit 0 {family inet {address 11.11.11.2/24;}}}protocols {oam {ethernet {link-fault-management {interface ae0;}}}}

2. Configure LFM on Router 2 for AE0:

   [edit]chassis {aggregated-devices {ethernet {device-count 1;}}}interfaces ge-1/0/0 {gigether-options {802.3ad ae0;}}interfaces ge-5/0/0 {gigether-options {802.3ad ae0;}}interfaces ae0 {unit 0 {family inet {address 11.11.11.1/24;}}}protocols {oam {ethernet {link-fault-management {interface ae0;}}}}
