This sets the AP's work mode for this template: normal(1) provides ordinary WLAN service, monitor(2) turns the AP into an attack-detection sensor instead of a service AP, and hybrid(3) combines WLAN service with device detection. Note that the object's own DESCRIPTION text still calls the third value "semiMonitor(3)" even though the SYNTAX enumerates it as hybrid(3) — an admin should go by the SYNTAX label hybrid(3) when setting this value, since that's what the enumeration actually defines.
