Network Interface ``NamePPA''. The Network Interface ``Name'' and
the ``PPA'' (Physical Point of Attachment) number are concatenated
together. A single hardware device may have multiple ``NamePPA'' identifiers,
which indicates multiple encapsulation methods may be supported on the device.
For Ethernet/IEEE 802.3 links, the ``Name''
lan
is used to designate Ethernet encapsulation, and
snap
for IEEE 802.3 encapsulation. For other links (FDDI, Token Ring),
only the
lan
encapsulation designation is used.
