[mrtg] Error using SNMPv2c for high bandwith links

[Pedro M. Ruiz]

Hi all,

I've been trying to monitor a POS (155 Mbps) link with a 5 minutes 
polling but the IFInOctets and IFOutOctets counters get overflow. So, 
I've started using SNMPv2c to use the 64 bits counters

I don't accept "Use 3 min polling as a response" ;)

However when I run mrtg I get the following error:

WARNING: Expected a number but got +13559816403068
WARNING: Expected a number but got +5739903263042

The router is a Cisco 12008 and this is my configuration:

WorkDir:/home/pedrom/test-mrtg
Refresh:2400

YLegend[xxxx]: MBits por segundo
Options[xxxx]: growright, bits, noinfo, nopercent

Target[xxxx]: 10:mycommunity at myrouter:::::2
MaxBytes[xxxx]: 19375000
Title[xxxx]: Estadísticas Línea xxxx
PageTop[flexnet]: <H1> Estadísticas Línea XXXX</H1>
  <TABLE>
    <TR><TD>Max Speed:</TD>
        <TD> 155 Mbps IP</TD></TR>
   </TABLE>
                      

Thanks in advance,
