ifMainEncapType

The encapsulation type to be used over the interface.
              
For Ethernet interfaces, the default encapsulation
type is ethernetV2(8). The other possible encapsulation
is llcSnap(6). If other(1) is specified then an
automatic encapsulation type learning method is used
in ARP for determining the encapsulation for unicast
destinations while the multicast and broadcast destinations
use ethernetV2(8).
              
For PPP and MLPPP interfaces, the encapsulation type can
only be other(1) and this is the default value.
              
For FR VCs, the value can be nlpid(2) (for carrying protocols
which have NLPID) or nlpidSnap(3) (for other protocols). The
default is nlpid(2) and the types of protocols supported are
inferred from the stack-layering implemented over the
interface.
              
For X.25 VCs, the value can be nlpid(2) or nlpidSnap(3) 
(where the VC can carry multiplexed protocol traffic with
each data packet containing the NLPID or SNAP header) or
cudNlpid(4) or cudNlpidSnap(5) (where the CUD specifies
the NLPID of the protocol or SNAP and the data packets do
not contain these headers - for dedicated VCs). The default 
is cudNlpid(4).
              
For ATM VCs, the default is llcSnap(6) but the 
vcMultiplexed(7) encapsulation is also supported.
              			
This object is not applicable to other interfaces.
