For whatever reason, the graph is not accessible at the site noted in the
footnote below. Pure guess without looking at the graph is the path
between the Linux box and the 1720 is less then reliable (or over utilized)
causing multiple snmp polls (which are udp-based) to be missed. If you're
sure that's not the case, look at the contents of the mrtg log file for
this device and include several lines of that in your next post.
