Configuring Port Mirror
Port Mirror is a mechanism for enhancing the security on local area networks by configuring one
port to monitor the other ports. Any network activities on the LAN are then tracked and recorded
when the Port Mirror feature is enabled. The default setting for this option is disabled.
To enable Port Mirroring:
1. Select Network Configuration > LAN Setup from the main menu, and then click the Port
Mirror tab. The Port Mirror screen will display.
2. Select the Yes radio box to enable Port Mirror.
3. Select the LAN radio box for the port you want to enable as the mirror port.
4. Check Egress , Ingress or both checkboxes to specify incoming and outgoing monitoring of
the ports to be monitored. Check the desired Ingress (traffic coming in) and/or Egress (traffic
going out) checkboxes of the ports for which traffic is to be monitored.
5. Click Apply to save your settings.
Tip: The Secondary LAN IP address will be assigned to the LAN interface of the
router and can be used as a gateway by the secondary subnet.
Note: The corresponding Egress port must be selected to the Ingress port is selected;
for example, if Ingress port 2 is selected, then Egress port 2 must be selected as
well.
