The counters are not updated instantly, there is lag, about 5s or so. On some
platform might be 30s.
If you are polling IFD (as opposed to IFL) the IFD counters should include
aggregate count from all the IFLs.

I would also recommend polling 64b (H) versions of the counters, i.e.

IF-MIB::ifHInOctets.723
IF-MIB::ifHInUcastPkts.723
