FortiGate 300E / 301E and 500E / 501E port s1, s2, vw1 and vw2

does anyone know any documentation which explains about these interfaces (a bit more)?

when i search i find the acceleration guides / pages on these devices, but nothing specific on their usage.

i assume they point to sniffing and virtual wires, but is there something special associated or is it just a name like dmz or ha?

checked with support, if the configuration involving them is removed then they can be used as regular ports.
