Hi, I want to find out if anyone has seen this issue with wing4.x/AP7131 v4.x code base during auto-upgrade. One of our customers had 4 RFS7000s in the cluster and they were running wing4.3.3/ap7131 v4.1.2. Preference IDs are configured for these APs to get adopted to particular controllers.They upgraded RFS-4 to 4.3.4. All the APs from RFS-4 went to RFS-3. On RFS-4, they copied new 7131 v4.1.4 image and made sure aap-auto-upgrade option is enabled. On RFS-3, the APs were reset in order for APs to get the new image from RFS-4, instead AP7131s went to un-adopted state and from the serial console to one of those AP showed that AP LAN1 IP is assigned to a static IP - 192.168.0.1. AP LAN-1 interface was originally configured as a DHCP client. DHCP Option-189 is used to get the RFS IP addresses to the AP. Regards, Ashutosh
