As you know, When We configure the interface to mirroing destination interface, the show interface output like "line up, protocol down". Right?
generally, the interface protocols is down so the traffic didn't forward to any other destination. it didn't lookup the systme routing table.
the traffic goes from other station to mirroring destination interface, the packet is dropped that's interface.
but. in the mirroring destination interface, the inbound traffic is a little. this traffic will be dropped in port(mirroring destination interface)?
