This is true, and here is next thing:

If you want to have right speed on NOT channelized interfaces (X.21, V.35)
you must set "bandwidth" on interface in Cisco router.
Example:
interface Serial0
 bandwidth 64

This gives you right speed in MRTG, when you make config by cfgmaker.
This is not needed on channelized interfaces (E1, T1), where is bandwidth
computed automatically by router from number of used timeslots.

Best regards,

Pavel Ruzicka
