so i've created a small lab network which includes 3 vlans and a dhcp server to distribute ip addresses. everything seems to be working well - devices can ping each other across different networks.
i added a wlc into the network and i was able to remotely connect to it with a pc to configure it, including the vlan its under and the network settings applied on it. problem is, after i apply the settings im unable to access the wlc from anywhere, not even the switch\routers can ping it. i checked all ip addresses are unique (because wlc management address is configured manually), so im not really sure where is the problem.
ive added my network topology below, feel free to check it out.
would be awesome if i could get a suggestion!

if you configure a vlan on the management interface, packets are sent with a vlan tag, vlan 0 results in untagged packets
you need to configure the corresponding switchport it is connected to as a vlan-trunk

you seem to be correct, thanks for that!
after configuring management vlan to be 0 i did have access to it after reboot. i tried setting it up as vlan 30 afterwards and make the switch port connected to it into a trunk, but it didnt seem to work. command was as follows:
int gi1/0/1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk native vlan 1
int vlan 1
no shut
doesnt seem to work. any idea why?
