I have been going over some of the switching subjects, specifically
SPAN and am trying to use a router as a monitor/sniffer. I thought that
there was a way to do this, but I can't seem to get it to work. I have
set up IP on the fastethernet interface of a 3640, and set the interface
to "no ip route-cache" to see the debug packets. Then, did a "debup ip
packet detail".
When I set up the SPAN, I can do the show command on the switch and
notice that it is in monitoring, and packets are sent out of the
interface.....however, the packets are not being received at the router
interface that is doing the monitoring (or suppose to be doing the
monitoring). Any thoughts? Maybe this just can't be done, but I
thought someone did this before.
