When configuring HA, I typically configure the LMS IP in the AP System Profile and let the Backup LMS be inherited from the HA configuration (DUAL mode). However, I have a customer that has the HA configuration AND LMS/Backup LMS configured. I have heard that this can cause issues with some APs, but don't know the specifics as to what issues.
Could having both of these configured cause APs to reboot or have trouble coming up completely? We have APs that will randomly start rebooting and will show as UP for about 1m30s and then go back down. Random APs at different locations, fix has always been to just replace the AP with another, but would like to identify the root cause, this happens on a regular basis, but customer has over 2000 APs deployed across multiple controller clusters (Master/Local).
Running 6.3.1.16 w/ AP's 125, 135 and 225. Happens to all models.
