AP GRE Tunnel
Generic Routing Encapsulation (GRE) is one of the available tunneling mechanisms which uses IP as the transport protocol and can be used for carrying many different passenger protocols. The tunnels behave as virtual point-to-point links that have two endpoints identified by the tunnel source and tunnel destination addresses at each endpoint.
Use the GRE Tunnel screen to view information on the traffic flow in a Generic Routing Encapsulation (GRE) tunnel.
To view the access point‘s GRE Tunnel statistics:
- Select the Statistics menu from the Web UI.
- Expand the System
node from the navigation pane (on the left-hand side of the screen). The
System node expands to display the RF Domains created within the managed
network.
- Expand an RF Domain node, select a controller or service platform, and
select one of its connected access
points. The access point's statistics menu displays in the right-hand
side of the screen, with the Health tab selected by default.
- Select GRE Tunnel.
The screen displays in the right-hand pane.
