minimum-links (Interfaces)



Hierarchy Level

Release Information

Statement added in Release 10.1 of Junos OS.


For redundant Ethernet interfaces configured as 802.3ad redundant Ethernet interface link aggregation groups (LAGs) in a chassis cluster only, set the required minimum number of physical child links on the primary node that must be working to prevent the interface from being down. Interfaces configured as redundant Ethernet interface LAGs typically have between 4 and 16 physical interfaces, but only half, those on the primary node, are relevant to the minimum-links setting.

If the number of operating interfaces on the primary node falls below the configured value, it will cause the interface to be down even if some of the interfaces are still working.


number—For redundant Ethernet interface link aggregation group links, specify the number of physical child links on the primary node in the redundant Ethernet interface that must be working. The default minimum-links value is 1. The maximum value is half of the total number of physical child interfaces bound to the redundant Ethernet interface being configured or 8, whichever is smaller.
