AP-7522E does not take VC configuration and wireless networks doesn't work

I configured an access point AP-7522E as a Virtual Controller with three vlan to use in three separate networks: one for corporate use that should connect to our existing LAN, another for employees and another for guests. Everything works very well when this AP is the only one in the network. As soon as I try to add a 2nd one to the pool, it doesn't take the vlans configured in the VC and no internet access is given. How to connect a second access point and configure it to an existing VC?

Have you verified that the VLANs are propagated throughout the wired switching infrastructure?

Thanks Andrew for your quick answer. I'm not much of an expert in networking, but we have only one VLAN in our switch for our wired infra and we wanted to create the other VLANs in the wireless virtual controller to associate the wireless networks to those VLANs only. I don't know if it's the right thing to do...

The recommended way would be to have 3 vlans on your corp router to which the 3 vlans on the AP are mapped.

If you have only one corp vlan and 3 on the AP then Natting needs to be configured on the AP for this to work. 

Here's a link to an article on same:

Hello Jorge,

You might be trying to adopt an AP to a virtual controller on a routed switch. This link will provide you with more information on this:

https://gtacknowledge.extremenetworks.com/articles/Solution/Not-able-to-adopt-WiNG-Express-APs-to-a-...

If this is the case, you will have to start by making sure that all vlans are allowed on the switchport. Then follow the instructions herein. 

I short, the vlans have to be allowed on both, the switchport and ge1 ports for traffic to go through. 

Regards,

Chris

Are the APs on the same firmware versions? Please verify firmware version on both and report. 

The VC will upgrade the adoptee only if the upgrade firmware was uploaded to it.

Hello Robert,

Yes, they both have the same firmware version: 5.8.5.0-016R. We have them since two weeks ago, so they have the original firmware that came from the factory.

Thanks!

Can you log in via SSH ( putty.exe) to either one and ping the other?  Also, can you get us the output of command ' show mint neighbors'

Yes Robert, I can connect to either one via SHH and ping each one without a problem. 

Also, here's the output of "show mint neighbors", doing it from the VC:

ap7522-362BF8>show mint neighbors
1 mint neighbors of 1B.36.2B.F8:
1B.36.2C.58 (ap7522-362C58) at level 1, best adjacency vlan-1

Additionally, there is something weird going on: the VC IP adress is 192.168.1.10 and the 2nd AP IP adress is 192.168.1.11, so in this last one the VC should be set to .1.10 but when I unplugged the VC and connect to the 2nd AP (1.11) the VC IP adress by default is set to 192.168.1.148 and level "Centralized". I don't know if that could give you any more lights....

Thanks!

if you look at the model numbers of both APs, are they both AP7522E or is one AP7522 (or AP7522i) and the other AP7522E. Please confirm. 

On the VC, under access points do you see the client AP listed in there?

Are they connected to a layer 2 or layer 3 switch?

Hi Andrew,


Are you doing any NAT? And who is the DHCP server in this mix? Is it when your clients connects to the VC all is good? In a VC environment for NAT and DHCP to work seamlessly, it's better if you have another device on your network handling these task, NAT and DHCP.

Orson
