Configuring Port Mirroring

The Switch allows you to copy frames transmitted and received on a port and redirect the
copies to another port. You can attach a monitoring device to the mirrored port, such as a
network sniffer or an RMON probe, to view details about the packets passing through the first
port. This is useful for network monitoring and troubleshooting purposes. To view the Setup
Port Mirroring window, click Port Mirroring in the Configuration folder.
To configure a mirror port:
1. Select the Source Port from where you want to copy frames and the Target Port,
which receives the copies from the source port.
2. Select the Source Direction, Ingress, Egress, or Both and change the Status drop-
down menu to Enabled. None is equivalent to Disabled in the Status pull-down
menu.
3. Click Apply to let the changes take effect.
addresses must be manually entered into the forwarding table. This is
sometimes done for reasons of security or efficiency. See the section
on Forwarding/Filtering for information on entering MAC addresses
into the forwarding table.
