Using Extreme IQ as our wireless controller, L3 switch and core switch are Cisco Catalyst 4500X. I change the IP helper for a VLAN that is used for addresses for our APs and they get an IP address from the new DHCP server, but cannot connect to the AP controller or be pinged from the core switch. The scope was copied directly from our current DHCP server to the new one. I've tried clearing arp cache on core switch and L3 but that did not allow connectivity.
Any suggestions on what direction to take? Thank you!
