<div dir="ltr"><font face="tahoma" size="2">1) Use SNMPv2 on both polls, so you get 64bit polling. Make sure you have a later version of MRTG. If one of the components is 32bit then you will get counter wrap at 32bit, IE about 115Mbps.</font></div>
<div dir="ltr"><font face="tahoma" size="2">2) Set up two separate targets, one for each interface, then use Routers2 as a frontend and make a userdefined summary graph over the pair with a total line.</font></div>
<div dir="ltr"><font face="tahoma" size="2">3) Change to polling every 1min and change your Interval: setting to be 1 minute, and recreate your .rrd files. Then you can cope with up to 575Mbps.</font></div>
