Load-interval?!
Load data is gathered every 5 seconds, and u can't change it as u can see in
output of show interface (it changes every 5 seconds),
"Load-interval 30" makes router to calculate average rate based on "each 30
seconds" instead of 5 minutes, its not related to data gathered by snmp, if
u use MRTG it calculates (by Default) your bandwidth consumption based on
Bytes instead of bits for each 5 minutes.
