The IfInOctets. MIB variable accumulates from device power-up basically
forever or until it wraps around through it's 32-bit capacity. It does
NOT reset automagically after a certain set number of seconds.
It is a "Counter" variable. If you wish to use it to measure interface
bandwidth or something, you'll have to do some arithmetic and calculate
delta values (value2 - value1 = delta) while watching out for the
counter wrapping around.
A good reference to look at is RFC1573, "Evolution of the Interfaces
Group of MIB-II" available at:
