[mrtg] graphing cisco virtual interface/PPPoE users

[Jan Ferré]

Hi Patrice

I suggest you make your own cfgmaker:
    Make a list of all possible interfaces/ifnumbers on the router
    Retrieve the descriptions/ifalias
    Set up your mrtg configs

This can fairly easily be done in e.g. perl and I would expect you to
run the script before each run of mrtg - even if this might make messy
datafiles. Like ... one session ends with 40 mill bytes transferred -
the next session starts at zero. Will this make mrtg have problems?

Best regards
