I have assigned all three NICs IP addresses that are outside the DHCP pool. I have 2 NICs are connected to 1 switch and the 3rd to my second switch.
I want to assign one of the two NICs on the 1st switch to "normal" network activity (e.g. internet access, RDP, etc.)
The other two NICs I want to reserve for mirroring ports on their respective switches.
While this machine is connected to the domain I can access the internet and Remote Desktop. I have no idea which NIC I am using until I start mirroring a port, at which time, if I happen to be connected through one of the NICs I have dedicated to mirroring, I lose my remote desktop.
Thank you for your assistance.
EDIT: I wish to capture packets on the NICs that I mirror ports on using Wireshark, Netminer, or NetWitness.
