Mirroring
This chapter discusses port mirroring setup screens.
14.1 Port Mirroring
Port mirroring allows you to copy a traffic flow to a monitor port (the port you copy the traffic to) in
order that you can examine the traffic from the monitor port without interference.
The Switch supports both local port mirroring and remote port mirroring.
In local port mirroring, the mirroring ports (through which traffic you copy passes) and the monitor
port are on the same device.
In remote port mirroring (RMirror), the mirroring ports and monitor port can be on different devices
in a network. You can use it to monitor multiple switches across your network. The traffic from the
source device’s mirroring port(s) is sent to a reflector port for VLAN tagging and copied to the
connected port(s). Traffic are then carried over the specified remote port mirroring (RMirror) VLAN
and sent to the destination device’s monitor port through the connected ports that connect to other
switches.
