[mrtg] MRTG returning 0s

[Gaurav Ghimire]

Dear all,

I am polling my switches for the traffic analysis of them by MRTG, for 
all other ports it shows correct values with the same type of 
configurations. But for few ports it only returns 0 and shows no graphs. 
When I run snmpwalk on them i can find that the counters are increasing 
as normal but why isn't MRTG polling any graphs for them whereas it is 
for other ports with the same configurations.

Regards,

Gaurav
