ifMainNetworkType

This object indicates whether this interface is a 
WAN or LAN link.
              
The default value for this object varies according
to the interface type. All interfaces of type radio (71),
ieee8023ad (161) and l3ipvlan (136) are LAN interfaces.
Fast ethernet interfaces are considered LAN interfaces
while Gigabit ethernet interfaces are considered WAN
interfaces at start-up.
Interfaces of any other type are WAN interfaces.
              
This object can be set only for ethernet interfaces or
l3ipvlan. For changing the network type of an ethernet 
interface or l3ipvlan, the interface must be brought 
down first - changing network type while the interface 
is administratively up is not permitted.
