GRE Tunnel Not Configured?

The engineer who built our WLAN as now left and I'm trying to better understand the WLAN.After reading I know the AP's build their GRE Tunnel to the Master Controller, but when I log into the WebUI, go to Configuration, IP, and GRE Tunnel, I do not see a GRE Tunnel configured. We are using VRRP and LMS-IP also IP DHCP Pool. I understand that the VRRP and LMS-IP is an IP the AP can reach on the controller, if know GRE Tunnel is configured, what excatly is the GRE Tunnel?

I'm assuming it's the IP DHCP Pool config for that specific network.

Re: GRE Tunnel Not Configured?

The GRE tunnel is an administrative construct built behind the scenes automatically for access points.  The page you are looking at is only for GRE tunnels built manually between the controller and another device, like another controller.

That's what I thought, b/c I couldn't find the config for it. Just to clarify unless it's a manual GRE Tunnel, there is no further configuration (maybe a firewall rule to allow the GRE Tunnel port 47) to have the AP Tunnel to the controller?
