This is definitely something that we have a need for here. We have multiple locations with DSL backup links that terminate back here on an ATM DS1. Since these are backup links, without OAM I have no way of knowing when there is a problem with one. Qwest DSL support certainly isn't going to call me and let me know!
So, I've enabled OAM and now get a nice syslog message when the link goes down. This allows me to get a quicker start on my one-hour phone call with clueless tech support. ;-) John >>> "Chuck Larrieu" 1/31/02 8:55:17 AM >>> I'm asking because I don't know the real world answer, and don't have a lot of real world experience with ATM. My reading is that OAM will shut down interfaces when the end to end ATM PVC fails. Can you explain this in a bit more detail. Is this something you really want to happen in real world? Wouldn't this complicate things when the link comes back up? Chuck ""MADMAN"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > You need to enable OAM.
