I think this is a related question.
I have this set up that stops working at some point and I can’t figure out why.
Sw1 connects to the DHCP server, to the WLC and to Sw2 and Sw3. WLC has management IP address of 10.0.0.11 and server is 10.0.0.10.
Sw2 connects to Lightweight APs and to the end-user laptop.
The APs and the laptop use DHCP and the laptop can log in to the WLC through its GUI - https://10.0.0.11.
Everything works fine, wireless users authenticate to APs, APs have CAPWAP tunnels to the WLC.
When I create VLANs for management and sales etc. I assign the laptop’s interface on Sw2 to the management vlan, create other VLANs and set up a trunk between Sw2 and Sw1, and from Sw1 to the WLC, I cannot access the WLC’s GUI anymore. The native vlans on trunks are the same and other VLAN’s settings are fine, the interfaces trunk, but the connection between the laptop and the WLC’s GUI is lost.
Can anyone explain the problem with this set up, please?
Does each vlan need a dhcp pool?
Thank you in advance
