Good question. Looks like regular traffic to me (POP3/http/SYN/ACK stuff).
the cat behaves like a big HUB :-(
but the strange is: it's not all traffic passing over the switch, just sub-portions of the complete traffic.
mac-address-table is not overloaded or similar stuff, so i am really a bit curious where the error comes from.
i would assume something broken with stp or bridging modes (or port channel stuff.)
We would like to use the switch just as a normal "housing aggregation switch"
