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 ;)
Unicast traffic comes in, mac forwarding table is checked and traffic forwarded to the appropriate port. 1 byte in, 1 byte out. Port goes down (or spanning tree sends it to blocking), all mac entries for that port are removed, and traffic for those macs is now sent to all ports. 1 byte in, lots of bytes out. James
