What does priority 255 mean in a JSRP chassis cluster?

The show chassis cluster status command shows priority as 255 for a redundancy group.

{primary:node1}
root@SRX> show chassis cluster status
Cluster ID: 3
Node name                  Priority     Status     Preempt  Manual failover

Redundancy group: 0 , Failover count: 1
    node0                  100          secondary  no       yes
    node1                  255          primary    no       yes

Redundancy group: 1 , Failover count: 0
    node0                  100          primary    yes      no
    node1                  1            secondary  yes      no

Priority 255 means that a manual failover was initiated. Manual failover will show ' yes ' in that scenario.

After a manual failover, it is always recommended to reset the manual flag in the cluster status.  Otherwise, no additional failovers may occur for that redundancy group.

To remove manual failover state and restore proper priority state, use below CLI command.
