Hehe funny. I've seen my share of EX counter bugs (we have an awesome one right now where filtered traffic shows up on the subint but not the pysical, still trying to track that one down :P), and actually if you're going all the way back to 9.3 there were plenty of MX counter bugs back then too (double counting, half counting, ae inbound at 0, ae members seeing the entire ae counters, you name it and I saw it between 9.0 and 9.3). But this was definitely just wrong counters, verified with direct SNMP queries. Some people repoted it went away when they restarted mib2d, for us we had to restart mib2d following every RE switchover just to get snmp to return answers period, but it didn't help the logical counter issue. At this point all I can really say is being on the look out for it, and if you do see it make sure Juniper looks at it quickly because it goes away on its own and leave no evidence for them to debug it. :) -- Richard A Steenbergen <r...@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
