(Aruba650) (AP system profile "test") #lms-h?
lms-hold-down-period Amount of time AP needs to stay on backup LMS before
switching to primary. Range: 1-3600. Default: 600.
This stops the AP's from switching back during a bootup.
Or
The other way of doing this (if the master and local can be on the same subnet) is to use VRRP rather than bkup-lms-ip, we can set a delay before VRRP wil preempt.
(Aruba650) (config) #vrrp 1
(Aruba650) (config-vrrp)#preempt delay ?
<seconds> Delay in seconds (0-60)
So we can wait for the controller to come up before it takes over again + there is interface tracking etc.
