   Yup. My P130 does the same thing, and the Max 4k's I've worked with did
it too.
Every time the line drops and comes back up, it apparently gets assigned to
what
appears to be a random interface number. (Makes monitoring difficult)

   What I did was make a static cfg for the ethernet IF, hacked up a copy
of cfgmaker
so the output looked like what I wanted, then every 5 minutes, run a script
that
executes the mod'd cfgmaker, copies the cfg's together, then runs mrtg.
It's not
real pretty, but it works, even if the line goes down and back up.
