MRTG doesn't look at the clock rate, it looks at the ifSpeed SNMP OID; to change that, on a Cisco, use the "bandwidth" statement in the interface configuration section. If it's not a Cisco, you'll need to consult your vendor documentation to figure out how to change the value reported by the ifSpeed OID.

Out70.2 kb/s (4.5%) 37.8 kb/s (2.4%) 63.0 kb/s (4.1%) The max speed MRTG gave of the interface was 193.0kbytes.Also kindly please explain what the percentage represents...I have been pulling my hair and doing all sorts of calculation to find out what the percentages exactly means and what is it exactly representing Regards Venkat
