Hierarchy Level


For redundant Ethernet interface link aggregation group links, you can configure the minimum number of physical child links on the primary node in the redundant Ethernet interface that must be working. If the minimum number of operating child links falls below the configured value, the interface is marked down even if some of the child interfaces are working. LACP marks these operating child interfaces or links that are working, as out of synchronization. This enables a peer switch, that does not have the minimum link configuration, to mark its interface as down as well. The peer switch can be a Juniper Switch or any other third party switch. As a result, the interface is marked as down on both the switches until the number of operating child links is more than the configured value.

For an aggregated ethernet interface, you cannot configure all three configuration options, bfd-liveness-detection, minimum-links, and sync-reset at the same time.
