About this task
            You can enable three types of GRE traffic tunneling for a user profile: Layer 3
                Roaming, Identity-based, or Standard GRE tunneling.
            
                - Layer 3 Roaming allows you to adjust roaming thresholds so that a device will
                    disassociate with a wireless client that has roamed to it from another subnet
                    and has either been idle for a period of time, or whose traffic has dropped
                    below a specified threshold.
- Identity-based traffic tunneling tunnels guest traffic directly to the
                    network.
- Standard GRE tunneling tunnels traffic to non-Extreme Networks tunnel
                    endpoints.
