CHAPTER 16
Mirroring
16.1 Mirroring Overview
This chapter discusses port mirroring setup screens.
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.
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 ports is sent to a reflector port for VLAN tagging and copied to the connected ports.
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.
