Release Information

Statement introduced in Junos OS Release 9.0 for EX Series switches.

Hierarchy level [edit switch-options] introduced in Junos OS Release 13.2X50-D10 (ELS). (See Getting Started with Enhanced Layer 2 Software for information about ELS.)

Statement introduced in Junos OS Release 13.2X50-D15 for the QFX Series.

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.

Required Privilege Level
