9.0.2.0 Introduced on the S6000.
8.3.19.0 Introduced on the S4820T.
8.3.8.0 Introduced on the S4810.
Usage Information After you congure 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 congure 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).
