We have two Cisco WLAN Controllers. The Management Interfaces and the Access Points are in VLAN11 with 192.168.11.x /24. Now we wanted to change the Interfaces to VLAN1 10.96.56.x /23 but no Access Point can connect to them (APs are beeing left to VLAN11).
Every AP Join Message is:
Error Occured: Lwapp discovery request rejected
Error Occurred Reason: Layer 3 discovery request not received on management VLAN
There is no firewall between this VLANs. At the old state I could also connect an AP via VPN to this WLC. Now with the change, the H-REAP "VPN-AP" also can't connect.
Do someone have any ideas why this is a problem?
