[mrtg] Anyway to determine MaxBytes for a port....

[Westley Chang]

Hello,
   I understand that the cfgmaker allows you to perform an SNMP walk
that gathers snmp information about a particular router/switch.  I was
wondering if there is any way cfgmaker can determine the exact MaxBytes
for a specific port on a router/switch....  
   The reason why I asked is that I was tweaking a generic cfgmaker
script using different MaxBytes values to see if the graphs would be
different.  Both of these two scripts (e.g. A & B)  were essentially
identical except that I changed the MaxBytes values.  
   After polling for a couple of hours, I see that the y-axis (e.g.
port utilization) is a bit different.  Script B actually has a much
higher port utilization (maximum peak 48.0 k) than Script A (e.g.
maximum peak 35.0k) even though the MaxByte value was higher for script
A!  (Max Bytes value- 12500000)

 Is there any way to determine the exact MaxByte?  IF not,  is there a
Cisco CLI command that can be used to query the correct MaxBytes.....Any
assistance or help will be greatly appreciated.  Thanks!:)
