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).
