why would I get a clock change on my ATM interfaces? I see them in my syslog server just before the line protocol on the interface goes down. and then I lose all connectivity until the clock change is removed. Sometimes it goes down for hours..

 I have been fighting this problem for three days and can not figure it out.

Thank You.

I would talk to your provider about it- it sounds like they are having problems with your ATM circuit.

Thanks mikebernhardt, I have called them several times and they say their engineers are "doing testing" on the circuit, but I have been having this problem for 5 days now and they have no answer yet.  I was hoping to get a little insight in to what the issue may be so maybe I can prevent a clock change from happening in the first place...

Thanks again,

The clocking has to match on both ends- in the case of ATM, the ends are your router and their ATM switch. So there's not much you can do except hound them until they fix it.
