[edit chassis aggregated-devices ethernet lacp link-protection]

Description

Disable the ability to switch to a better priority link (if one is available) once a link is established as active and a collection or distribution is enabled.

Best Practice:

(MX Series) By default, Link Aggregation Control Protocol link protection is revertive. This means that after the current link becomes active, the router switches to a higher-priority link if one becomes operational or is added to the aggregated Ethernet bundle. In a highly scaled configuration over aggregated Ethernet, we recommend that you prevent the router from performing such a switch by including the non-revertive statement. Failure to do so may result in some traffic loss if a MIC on which a member interface is located reboots. Using the non-revertive statement for this purpose is not effective if both the primary and secondary interfaces are on the MIC that reboots.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 9.3.
