1.3.6.1.4.1.9.9.9998.1.1.2.1.1.1
An estimate of the interface's current bandwidth in
million bits per second. For interfaces which do not vary in
bandwidth or for those where no accurate estimation
can be made, this object should contain the nominal
bandwidth. If the bandwidth of the interface is
greater than the maximum value reportable by this
object then this object should report its maximum
value (4,294,967,295 bps) and ifHighSpeed must be used to
report the interface's speed. For a sub-layer which
has no concept of bandwidth, this object should be
zero.
