It has everything to do with SNMP version. Please read the documentation. In
"mrtg-reference", under "Extended Host Name Syntax" there
is explanation for the fields which are delimited by these ":". It's
just that most of the time people don't care to change the default timeout or
number of retries, but that pesky "2" at the end actually tells MRTG
to use SNMP v2 (as opposed to the default of v1), and you have to skip all the
other fields in front of it. <br>
It's simply that v2 introduced support for 64-bit counters. What you call
"regular" counters (actually 32 bit counters) are simply the only
ones supported by the default SNMP version used by MRTG - v1.<br>
