(ASCEND) Max flooding our ethernet backbone



Hi Everyone,

We have 2 Max4000's in one of our POP's that feed into a bay 350T 10/100
switch.

Since yesterday morning one of the Maxes is flooding our Ethernet backbone
in intervals of roughly 10-15 seconds (sometimes slightly longer)

When it does it all the lights on the hub light up & stay *constant*

My MRTG graph shows that when it happens every single machine connected to
the ethernet suddently shoots up by about 50-60kb/s

If I unplug the Max during one of these spurts, it immediately goes away.
If I unplug it & leave it out - everything runs fine.

The MRTG graph that I have that sums up all 16 ports on the hub into 1
graph shows it typically sending about 700kb/s. Typically this hub sends
about 60-100kb/s

Any ideas? I'm running out of things to do. Both Maxes are running 6.0.2
and have been fine for serveral months without changing anything. Remember
only 1 is playing up.

I upgraded it to 6.1.7 but that didn't change the situation so I
downgraded it back to 6.0.2

Any clues?

thanks
