The SDWAN Edge can be configured similarly to Gateway Devices. Any product of HSA/UA with edge template can be configured as a Edge device.
Most of the configuration menus for Edge can be referred back to Gateway Configuration. (LINK). Only the special configuration of Edge are listed here which is more for access point and client-side settings.
The user can also get access to Host Menu from the Table View of the SDWAN Edge tab by clicking on the dashboard icon in the Action column.
