It's very interesting to see the traffic stats at http://www.ams-ix.net/hugegraph.html Usually, incoming and outgoing traffic is the same. But during this problem, much more traffic went out than came in.
Curious, as the exchange sources no traffic that shouldnt really be possible ;)
(unless the graphs are inaccurate)
If there is something nasty happening with STP, or traffic is flooding, you will count the same traffic several times - once for each egress port that it hits - hence aggregate traffic out > traffic in. Broadcast traffic is also counted multiple times in aggregated stats. Mike
