[mrtg] Re: ifnum changes in Cisco routers

}Hi - 
}
}I'm trying to get some more information I can read about how / 
}why ifnum can
}change in a Cisco router.  Cisco tells me its only if a add/del an
}interface, and then, not in every case.  I'm seeing behaviour 
}which suggests
}its a little more random.  Can anyone suggest a source for 
}further reading
}on this topic?  
}
}I've converted my mrtg cfgs to anchor based on interface ip 
}address, but
}that creates some new challenges for me on some interfaces 
}that don't have
}IP addresses.  If you have any suggestions on how to handle a 
}device where
}some interfaces of interest have IP and some do not, I appreciate your
}guidance on that as well.
}

My suggestion (and practice) is to not reference anything by instance 
number. I use description or name like...

For IOS based ciscos I use:
cfgmaker --ifref=descr

For catOS based ciscos I use
cfgmaker --ifref=name
