Hi Andy,
have you looked at the RMON event/alarm capability? You configure the
router to send a trap when a mib object exceeds or falls below a certain level.
I think you could set some up to trap when the bytes received on an interface
dropped below a certain level or something similar. Or there may be some ATM mib
object which changes value when a connection is lost.
I can post an example if it would help.

Subject: L3 keepalives without routing protocol?
Hi all,
strange problem for y'all...
I have a problem whereby a down circuit does not necessarily "down" an interface
(via ATM switch - am using OAM but not foolproof). Is there some way that I can
enable a L3 keepalive without running a global IGP (bear in mind that this is
between my core routers and several thousand 25XX/26XX clients, and I don't want
to give them a routing table, just a default route).
We run a NOCOL-type daemon that alerts me if a machine has been unpingable for
>15 minutes, but am looking for a sure-fire way to have a core router send the
NMS a trap when a circuit becomes unreachable at L3.
any help much appreciated as always
Andy
