2504 - out of band management and topology change

[sysadmin2]

Due to business needs, I will have to reconfigure a WLC-2504 controller with out-of-band access. I've tried to implement a solution which worked for management access, but the APs werent able to talk with the controller.

My goal:

- management access using port #1 - IP 192.168.10.1 (not routed)

- AP VLAN on port #2 - IP 10.0.0.1

- WLANs on port #3. - Two Priv IPs

My AP vlan has a DHCP serving IPs to the APs and passing the option 43 with the WLC port#2 IP address, 10.0.0.1.

What I see is once the APs are able to talk with the 2504, they want to register with the 192.168.10.1. That network is isolated.

Is this a valid topology?

I noticed some setups with the WLC ports connected to independent switches and set of APs, but the ports on the WLC using the same subnet /24 , like

Port #1 (management) 192.168.50.1

Port #2 192.168.50.2

Port #3 192.168.50.3

Port #4 192.168.50.4

So does an AP connected to the Port#2 talk with the management interface in Port#1? They are NOT interconnected outside of the WLC.

Thanks!

Hi,

The management interface should be reachable to APs. Have a look at the following doc for explanation:https://www.cisco.com/c/en/us/support/docs/wireless/2500-series-wireless-controllers/113034-2500-deploy-guide-00.html

Look at the section:"Controller configuration through the CLI"

thanks

It sounds like the AP Manager is not enabled on the Interface that is using Port #2.  

Go to Controller > Interfaces

Select the interface with ip 10.0.0.1 

It should be using port #2, based on your description.

Click the Enable Dynamic AP Management checkbox.

Reboot the AP
