One doubt will it monitor particular vlan or particular port. I have used SPAN for packet analysing , but I would like to know whether it will monitor particular VLAN subnet i.e for example vlan 24 subnet is 10.3.24.0/24 , vlan is spanned across campus.
On a particular switch it will monitor the local VLAN only. If you have Vlan spread across the campus and you want to monitor this vlan campus wide, then you have to setup the Remote SPAN on all the switches. This way the traffic from each remote switch for vlan 24 can be spanned and will be send to monitoring station connected to the final switch.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
