[mrtg] Re: configure mrtg for a 1000M network router

[Michael Earls]

I use the command line cfgmaker to build the configs

cfgmaker --ifref=nr --snmp-options=::1:1::2 --ifref=eth --ifref=descr

counters. This feature gets activated by switching to SNMPv2c.
Unfortunately not all devices support SNMPv2c yet. If it works, this
will prevent your counters from wraping within the 5 minute polling
interval, since we now use 64 bit instead of the normal 32 bit.

You can also add the SNMPv2 option when building a config using 
cfgmaker.  Try:

--snmp-options=:::::2

on the cfgmaker command line.  That'd be the quickest way to find out
if 
your switch supports HC counters.
