5.10.2 Configuring Remote Port Mirroring

In this example, there are three switches (A, B and C) in your network. You are connected to port 10 of switch C but want to monitor traffic received or transmitted on port 4 of switch A. The copied traffic is forwarded to remote port mirroring VLAN 100.

In Switch A:

1Access the Switch through http://192.168.1.1. Log into the Switch by entering the username (default: admin) and password (default: 1234).

2Go to Configuration > Port Mirroring. Select Enabled in the Mode field to activate mirroring on the Switch.

3Set Type to Source to configure a source port on Switch A.

4Enter the remote port mirroring VLAN ID number (100 in this example) and select a reflector port (Port 7 for example) through which copied traffic is forwarded to the specified VLAN. The Switch will automatically create the remote port mirroring VLAN and configure the reflector and intermediate ports as a member of the remote port mirroring VLAN.

5Select the direction of traffic flow you want to copy (Both in this example) on the source port (port 4 in this example).

6Configure port 12 to act as an intermediate port to which traffic from the source port is copied that connects to Switch B.
