Setting up Mirroring or "Sniffer Ports"
Port Mirroring allows you to configure traffic from any number of ports to be copied (mirrored) to
your selected "sniffer" port, which may be any port that is not a source port. This traffic may be
selected from transmitted or outgoing (egress) frames, received or incoming (ingress) frames or all
frames. A port cannot be both a mirrored and a destination port at the same time. Sniffing may be
disabled globally.
To configure port mirroring:
1. Select Monitoring > Mirroring. The Port Mirroring screen will display.
2. From the Destination Port pull-down menu, select a port to be the destination port. All
mirrored traffic will be routed to this port.
3. From the Mirroring pull-down menu, select the mirroring mode. The possible settings are:
•
Tx and Rx. Mirrors both incoming and outgoing traffic on the designated source ports.
•
Rx Only. Mirrors only the incoming traffic to the designated source ports.
•
Tx Only. Mirrors only the outgoing traffic to the designated source ports.
•
Disable. Disables port mirroring globally.
4. Select the Source Port check boxes for the ports to be mirrored. Clear the check boxes for the
ports you do not want to be mirrored.
5. Click Add.
