Windows DHCP server migration broke Ruckus Wireless Network

[tom_moseley_mos]

We migrated our DHCP server from an old server to a new one when we decomissioned our admin network and now just have a single domain and network.

DHCP is working fine with our wired clients.

It has broken our wireless network. Ruckus Zone Director 3000 and APs ZF7363

You try connect to the wireless and it wont let you connect, it fails to assign an IP address. The APs keep restarting as they are failing to get the heartbeat from the ZoneDirector. 

The wireless network worked fine until the DHCP was migrated then it is playing up. We have even restored the zone director to factory settings but still having the same issue.

Anyone any ideas?

Thanks

You are probably using a security feature on your switches that inspects arp and dhcp packets. Disable dhcp-inspection. Your switch is dropping the DHCP requests to the new DHCP server. It thinks the new DHCP server is rogue.

Once you disabled the feature and the everything works, you may re-enable it. You will also find info on how to reset that database in the switch.
