3.3 Port Mirroring Configuration

3.3.1 Introduction to Port Mirroring

Port mirroring refers to the duplication of data frames sent/received on a port to
another port. The duplicated port is referred to as mirror source port and the duplicating
port is referred to as mirror destination port. A protocol analyzer (such as Sniffer) or
RMON monitoring instrument is often attached to the mirror destination port to monitor
and manage the network and diagnostic.
This switch supports one mirror destination port only. The number of mirror source
ports are not limited, one or more may be used. Multiple source ports can be within the
same VLAN or across several VLANs. The destination port and source port(s) can be
located in different VLANs.
