It looks like all this traffic goes from slot 4 through fabric to Sup (slot 6). I thought it was multicast, but according to "show ip mroute count" multicast gets only 500-600Mbps.
According to "show mls statistics" there is a lot of L2 traffic. May be it`s "unknown MAC" traffic punted to Sup ? I can`t remember the command which can show counters for switched known/unknown MAC frames, something like "show mls..."
Thanks in advance,
Kirill
