Sniffer Port
A lot of times a mirrored “destination” port cannot send traffic. It is placed into a “listen-only” mode. The way to get around this is to use a bi-directional network tap between your sniffer and the device you want to capture traffic to/from. See my blog series on <a href=”http://itknowledgeexchange.techtarget.com/itanswers?s=network+taps&searchtype=IT+Blogs&x=28&y=6″>Researching Network Taps</a>.
