Mirroring
This chapter discusses port mirroring setup screens.
16.1 Port Mirroring Overview
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.
Local Port Mirroring
In local port mirroring, the mirrored ports (through which traffic you copy passes) and the monitor
port are on the same device.
Remote Port Mirroring
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. Traffic from the
source device’s mirrored port(s) is sent to a mirroring port for VLAN tagging and forwarded to other
switch(es) in the same remote port mirroring (RMirror) VLAN. Traffic are then carried over the
specified RMirror VLAN and sent to the destination device’s monitor port.
Note: If the Switch is not acting as a source or destination device in remote port
mirroring, you need to enable port VLAN trunking to allow traffic belonging to the
specific RMirror VLAN to pass through it. Alternatively, you can configure a VLAN
group for the mirrored traffic.
