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:
1 Access the Switch through http://192.168.1.1. Log into the Switch by entering the username
(default: admin) and password (default: 1234).
2 Go to Configuration > Port Mirroring. Select Enabled in the Mode field to activate mirroring on
the Switch.
3 Set Type to Source to configure a source port on Switch A.
4 Enter 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.
5 Select the direction of traffic flow you want to copy (Both in this example) on the source port (port
4 in this example).
6 Configure port 12 to act as an intermediate port to which traffic from the source port is copied that
connects to Switch B.
