Usage
Information
After you configure a VLT domain on each peer switch and connect (cable) the two VLT peers on each
side of the VLT interconnect, the system elects a primary and secondary VLT peer device. To configure
the primary and secondary roles before the election process, use the primary-priority command.
Enter a lower value on the primary peer and a higher value on the secondary peer.
If the primary peer fails, the secondary peer (with the higher priority) takes the primary role. If the
primary peer (with the lower priority) later comes back online, it is assigned the secondary role (there is
no preemption).
