Can't access WLC

hs08 — Thu, 27 Apr 2023 02:18:03 GMT

Hello,

Anyone know why i can't access to the WLC if i access the WLC from VLAN which the VLAN listed in controller interface?

On the pic we can see i have some VLAN and if i access from that VLAN , the WLC can't be accessed.

- As these are dynamic vlans mapped to WLANS you probably need to enable management via wireless as explained in : https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/b_cg74_CONSOLIDATED_chapter_010110000.pdf

You can, but you need to enable it.

config network mgmt-via-dynamic-interface {enable | disable}

Sorry dont follow you. Interface vlan on cisco wlc is called dynamic interface.

I undertood from your post that you are trying to http or ssh to the wlc on this interfaces and are not able to, correct?

The commamd I shared allow you to do that. It is not management interface, it is dynamic interface I am not saying management via wireless, it is something else.

Did you run the commamd? Did you try access after that?

- Make sure you don't have any firewall in between blocking the particular access 2) Check the controller logs when this is attempted 3) Try with google chrome , press F12 , check what you see in the development pane when trying ,

Then the problem is not on the WLC.

If you are trying to reach the WLC from a different network, make sure routing is ok. WLC is not a layer3 device but it is possible to add routes on it.

And devices along the way must be checked also.

You can provide the topology and device config for further support.

Indeed another option to test port 443 (https) reachability is to use an nmap port scan as in :
% nmap -p443 --reason WLChostname

Can you access the WLC from any other interface?
Do you have a CPU access list applied?

What is the DNS for the WLC, when you try to manage it via web, are you doing it by name, or IP. is HTTP to HTTPS redirect enabled, if not make sure the web is doing https as if you are trying IP it usually defaults to http.
