Hey,<div><br></div><div>Has anyone experienced this before.</div><div><br></div><div>I have configured MRTG to poll my cisco 7201 router. </div><div><br></div><div>However, the bandwdith utilisation graphed by MRTG is way lower than the output from "Show interfaces"</div>
<div><br></div><div>I have performed an snmpwalk and compared the output from the snmpwalk on the server running MRTG to the output from "show interfaces Gigabit...." and they are quite similar. Showing the right information is being polled.</div>
<div><br></div><div>An example of comparing outbound octets:</div><div><br></div><div><i>><b>Show interface GigabitEthernet 0/2</b></i></div><div><i><b>.....................</b></i></div><div><i><b>....</b></i></div><div>
