Configuring Port Mirroring
Port mirroring monitors network traffic by sending copies of all incoming and
outgoing packets from one port to a monitoring port. You can use port mirroring as
a diagnostic or debugging tool, especially when fending off an attack or viewing
user traffic from LAN to WAN to see if users are accessing information or websites
they are not supposed to.
The LAN host (PC) should use a static IP address to avoid any issues with port
mirroring. DHCP leases can expire for a LAN host and can cause port mirroring to
fail so if a static IP address is not configured for the LAN host.
To configure port mirroring:
STEP 1 Choose Administration > Diagnostics > Port Mirroring.
STEP 2 In the Mirror Source field, select the ports to mirror.
STEP 3 From the Mirror Port drop-down menu, choose a mirror port. If you use a port for
mirroring, do not use it for any other traffic.
STEP 4 Click Save.
