Release Information
Statement introduced in JUNOS Release 9.0 for EX-series switches.
Description
Configure a primary link and secondary link on trunk ports. If the primary link fails, the secondary link automatically takes over as the primary link without waiting for normal STP convergence.
Options
-
interface interface-name—A logical interface or an aggregated interface containing multiple ports.
-
primary—(Optional) Specify one of the interfaces in the redundant group as the primary link. The interface without this option is the secondary link in the redundant group. If a link is not specified as primary, the software compares the two links and selects the link with the highest port number as the active link. For example, if the two interfaces are ge-0/1/0 and ge-0/1/1, the software assigns ge-0/1/1 as the active link.
