This morning I decided to install Ntop on a XP station that is only running an MP3 server right now. I installed it and everything worked fine. Now, wanted to mirror all the traffic going out of the network to the XP box so that Ntop can get statistics and all that good stuff. When i mirrored port 1 (goes to the firewall - the to the router) to port 24 (XP box running Ntop), the traffic is being recorded - but I can no longer remotely access the XP box nor ping it. As soon as I remove the mirror on the switch, the XP box can be remotely accessed and pinged. Im kinda confused as to what's happening here....could anyone clarify and explain why this is happening?
