Ok, does anyone have a brief explanation, or example of a config, for using MRTG with a Netserver / Total Control? I would like to monitor the number of modems in use out of the total active ports (which could change from time to time - re-making the config is ok there if I need to), and possibly the total bandwidth usage - either per port, total, or both. I tried following the example found at the link below, but just got a lot of MRTG errors after playing with various options, and figured someone might just be able to post a snippet of their config file. http://www.dcr.net/~mandrews/usrtoys/mrtg.shtml I know a tremendous amount of information can be gathered frrom SNMP on these things, I just don't know much about how to do it... Thanks, -rf
I was just going to post the same message about MRTG. We get far less information about the users online than we did with our older Equinox equipment. Of course, on the upside, the 3com stuff actually works days on end without a reboot unlike the Equinox stuff.

Make sure you look this over and change what needs to be changed. NOTE - I like my graphs to grow left not right so you may want to add the "growright" option. ###################################################################### # Description: 3Com Corporation HiPer Access Router Card Built on Jan 10 2002 at 12:07:57. # Contact: Lewis Bergman # System Name: totconabi1 # Location: Abilene #..................................................................... # ### Concurrent Modem Users >> Descr: 'U.S.Robotics Concurrent User's ### # This Report File Template measures Concurrent Modem Users # on a 3Com HiPer Arc # # Example CFGNAME: [DEVICE NAME]-hiper_arc_concurrent_users Target[3comTC.modem]: 1.3.6.1.4.1.429.4.2.1.10.0&1.3.6.1.4.1.429.4.2.1.10.0:comm@192.168.1.203 MaxBytes[3comTC.modem]: 192 Unscaled[3comTC.modem]: dwm Title[3comTC.modem]: totconabi1 3Com Total Control Modem Usage PageTop[3comTC.modem]: <H1>totconabi1 3Com Total Control Modem Usage</H1> Options[3comTC.modem]: gauge, unknaszero YLegend[3comTC.modem]: Modem Users ShortLegend[3comTC.modem]: users Colours[3comTC.modem]: GREEN#00eb0c,BLUE#0000ff,GRAY#AAAAAA,VIOLET#ff00ff Legend1[3comTC.modem]: Concurrent Modem Users Legend2[3comTC.modem]: .

If I want to upgrade my ARC's to 128k ram and 16k flash, how do I do it? Do I need to order them from 3COM? When you swap the flash out, do you lose the software and/or configuration? thx, Aaron
