Hi
No - basically the IOS that is on your switch will maintain a collection of statistics and figures.
These figures can be collected (polled) by an SNMP management station.
The MIB you are talking about tells the management station how to interpret the figures and stats available on the switch.
Adding a newer MIB doesn't update the stats available on the switch - it just tells the management station what the figures mean.
If you have a MIB added to a management station, and some counters don't read, it may be that you need to update the IOS on the switch to a newer version to enable the counters or it may be that you aren't using the feature you are polling...
