Please log in for more thread options and sniff that vlan. If the vlan is sniffed, is all traffic except encrypted traffic vulnerable. Thanks | |||||||||||||||||||

Please log in for more thread options Mark Ofcourse you could configure vlan based span and monitor the traffic on dest port or you could do that as port based span as well. hope this link would be of help http://www.cisco.com/warp/public/473/41.html Thanks | |||||||||||||||||||

Although also depends what type of hardware/gear you are running. Spanning can be very intensive, and for smaller switches, I would stick to port spanning. Spanning trunks is perhaps the most dangerous for overrunning your hardware/memory. | |||||||||||||||||||
