This guide details how to to enable support for CoA / Disconnect Message on the Extreme IdentiFi controller. This is required in order to use the Tiered Bandwidth data cap and/or E-mail verification kick off feature.
Start by logging into your Extreme IdentiFi Controller.
Step 1 - Radius
Click VNS on the top menu and then DAS on the left. Set the following:
Port
3799
Click Save.
Step 2 - Firewall
IMPORTANT: CoA works by accepting inbound traffic from our RADIUS. We will send this request back to the same WAN IP of which your Extreme IdenFi controller uses for outbound traffic to our RADIUS. Therefore, you will need to forward port 3799 (UDP) on your firewall from this WAN IP to the internal Extreme IdenFi controller management IP on your local network.
