I have two WLC 4100, which just updated to the latest Software Version 220.127.116.11.
Everything works fine, except I have problems connecting to the configuration Website.
I have the following situation:
My client is connected in VLAN A, there is also a Dynamic Interface configured in that VLAN A. The Management IP is configured in VLAN B. The Vlans are routed and gateways and so on are correct.
The WLC is Layer 3 Mode.
With the older software release I could connect to Interface IP in VLAn A or the Management IP in Vlan B.
Now with the new software I cannot login on the interface IP on VLAN A anymore. Furthermore the Management IP on VLAN B is only "available" after I tried to connect to the interface IP on VLAN A.
Otherwise the Management IP does not even answer to a ping.
I am not quiet sure if this is a feature or a bug. Anyway it is very annoying
Hopefully somebody has a solution or at least the same issue, so I do not feel so alone ;-)
Thanks for your support
