Has everyone just become so used to terrible performace at MAE-East, or am I the only one seeing problems? I'm seeing perfect performance to networks connected to Gigaswitch 1 (excluding overloaded ports), but 15-20% packet loss to anyone connected to any other Gigaswitch. In the past MFS would jump on these tickets, find a frozen card on Gigaswitch 6, reset it, and clear the trouble. It has been over 24 hours since I opened a ticket, I've spoken with MFS Datanet Engineering, and I still don't think I've spoken to anyone at MFS who is aware that all traffic between Gigaswitches goes through Giga6. If anyone has time tonight, could they check performance to other providers on the same Gigaswitch and on other Gigas. If you need to know which provider is on which switch, go to http://www.mfsdatanet.com:80/MAE/east.map.html Thanks, and hopefully this is on topic, even if it doesn't contain actual router commands. :) Jeremiah Kristal Senior Network Engineer ICon CMT Corporation jeremiah@iconnet.net 201-319-5764 x284 internal
Well, from our router (1292.41.177.103, catalyst 6) it looks like this (note the packet loss!!!) Jan There the pings: core0.mae-east#ping 192.41.177.181 Type escape sequence to abort.

http://208.234.102.97/MAE/east.aggr.overlay.html The past two years it has been a pretty much smoothe curve in the traffic graph, but the past months (as soon as it started hitting 1500mbit/s) the graph started to get rugged the way it is now. I interpret that as trouble... It used to spike a few times a week max, nowadays it seems to do that hourly. I interpret that as overload. ----- Mikael Abrahamsson email: swmike@swm.pp.se
