Hi * had another weird problem I can't really understand ...
OK, we have a customer site hooked up via dual E1 links - two links going through two different carriers. I combined the two using a vanilla MLPPP, which worked fine for a while. Then I noticed network performance drop, as well as errors on the physical interface of one of the links, which seemed to be caused by the carrier connection, so we opened a ticket. Carrier checked the circuit, located some problems, but I couldn't get the line protocol on it anymore, not even a loop configured on the digital side (behind the X21-E1 converter) was visible from our end, though a link on the customer E1 interface was visible to me. After trying just about everything short of replacing the hardware (customer isn't located at our city, 1h drive), we decided I would drive there today and replace either the converter or the WIC-1T. Out of curiosity, I went in and configured the not working link not to use PPP anymore on both sides - and it came up instantaneously... WTF? No errors, link seems fine. So I went ahead and configured an additional transfer net, as well as the appropriate routes, so no I'm running fine with a dual E1, though not w/MLPPP ... So, any idea what could be causing this??? As I said, the configuration was working for a good month or so ... Tnx, -garry _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
