primary-priority

Configures the priority when selecting the primary and secondary VLT peers during the election.

Syntax
primary-priority value
Parameters
value — Enter a lower value than the priority value of the remote peer. The range is from 1 to 65535. The default value is 32768.
Default
32768.
Command Mode
VLT-DOMAIN
Usage Information
  • After you configure a VLT domain on each peer switch and connect 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.
  • If the priority values configured on the two VLT peers are equal, VLT uses the default primary election mechanism based on the values of the system MAC addresses of the two nodes. The VLT peer with the lowest system MAC address assumes the primary role.
  • If the heartbeat is up and the VLTi link goes down between the VLT peers, both the VLT peers retain their primary and secondary roles. However, the VLT port channel on the secondary VLT peer shuts down.
NOTE When you configure a priority for VLT peers using this command, the configuration does not take effect immediately. The primary priority configuration comes into effect the next time election is triggered.
