This table contains interface packet
statistics which are not available in
IF-MIB(RFC2863).
As an example, some interfaces to which
objects in this table are applicable are
as follows :
o Ethernet
o FastEthernet
o ATM
o BRI
o Sonet
o GigabitEthernet
Some objects defined in this table may be
applicable to physical interfaces only.
As a result, this table may be sparse for
some logical interfaces.
