Juniper EX3300 Hardware Guide

Before you configure LACP link protection, be sure you have:
•
Configured the aggregated Ethernet bundles—also known as link aggregation groups
(LAGs). See “Configuring Aggregated Ethernet Links (CLI Procedure)” on page 82.
•
Configured LACP for the interface. See “Configuring Aggregated Ethernet LACP (CLI
Procedure)” on page 86.
You can configure LACP link protection for all aggregated Ethernet interfaces on the
switch by enabling it at the global level on the switch or configure it for a specific
aggregated Ethernet interface by enabling it on that interface.

Configuring LACP Link Protection at the Global Level
To configure LACP link protection for aggregated Ethernet interfaces at the global level:
1. Enable LACP link protection on the switch:
[edit chassis aggregated-devices ethernet lacp]
user@switch# set link-protection
2. (Optional) Configure the LACP link protection for the aggregated Ethernet interfaces
to be in nonrevertive mode:
NOTE: LACP link protection is in revertive mode by default.
[edit chassis aggregated-devices ethernet lacp link-protection]
user@switch# set non-revertive
3. (Optional)To configure LACP system priority for the aggregated Ethernet interfaces:
[edit chassis aggregated-devices ethernet lacp]
user@switch# set system-priority
Configuring LACP Link Protection at the Aggregated Interface Level
To enable LACP link protection for a specific aggregated Ethernet interface:
1. Enable LACP link protection for the interface:
[edit interfaces aeX aggregated-ether-options lacp]
user@switch# set link-protection
2. (Optional) Configure the LACP link protection for the aggregated Ethernet interface
to be in revertive or nonrevertive mode:
•
To specify revertive mode:
[edit interfaces aeX aggregated-ether-options lacp link-protection]
user@switch# set revertive
•
To specify nonrevertive mode:
[edit interfaces aeX aggregated-ether-options lacp link-protection]
user@switch# set non-revertive
3. (Optional)To configure LACP system priority for an aggregated Ethernet interface:
