You can configure link protection for aggregated Ethernet interfaces to provide QoS on
the links during operation.
On aggregated Ethernet interfaces, you designate a primary and backup link to support
link protection. Egress traffic passes only through the designated primary link. This includes
transit traffic and locally generated traffic on the router or switch. When the primary link
fails, traffic is routed through the backup link. Because some traffic loss is unavoidable,
egress traffic is not automatically routed back to the primary link when the primary link
is reestablished. Instead, you manually control when traffic should be diverted back to
the primary link from the designated backup link.
NOTE: Link protection is not supported on MX80.

Aggregated Ethernet interfaces support link protection to ensure QoS on the interface.
To configure link protection:
Specify that you want to configure the options for an aggregated Ethernet interface.
1.
user@host# edit interfaces aex aggregated-ether-options
Configure the link protection mode.
2.
[edit interfaces aex aggregated-ether-options]
user@host# set link-protection
To configure link protection, you must specify a primary and a secondary, or backup, link.
