Configure Port Mirroring - NETGEAR MS510TX User Manual

Configure Port Mirroring

Port mirroring selects the network traffic for analysis by a network analyzer. This is done for
specific ports of the switch. As such, many switch ports are configured as source ports and
one switch port is configured as a destination port. You can configure how traffic is mirrored
on a source port. Packets that are received on the source port, that are transmitted on a port,
or are both received and transmitted can be mirrored to the destination port.
The packet that is copied to the destination port is in the same format as the original packet
on the wire. This means that if the mirror is copying a received packet, the copied packet is
VLAN tagged or untagged as it was received on the source port. If the mirror is copying a
transmitted packet, the copied packet is VLAN tagged or untagged as it is being transmitted
on the source port.

To specify one or more source ports and the destination port for port mirroring:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.

• To configure a single port as the source port, select the check box associated with the
port, or type the port number in the Go To Interface field and click the Go button.
• To configure multiple ports as source ports, select the check box associated with each
port.
Note: You can select only physical ports, not LAGs.
7. From the Destination Port menu, select the destination port to which port traffic must be
copied.
You can configure only one destination port, which must be a physical port, not a LAG.
The port functions as a probe port and receives traffic from all configured source ports. If
no port is configured, none is displayed.
