Picture 4.1.1 Port Mirror Configuration
Users can do Port Mirror Configuration in above page. Port mirroring is used on a network
switch to send a copy of network packets or data traffic from some ports (or an entire VLAN)
to a network monitoring connection on specified switch port. The original port is called Source
Port, and the specified port is Mirroring Port. This is commonly used for network appliances
that require monitoring of network traffic without influencing the normal working of every port,
it’s a convenient online-monitoring function.
All ports have mirroring function, but only one port can be configured as Mirroring Port. In the
same system, there is only one mirroring port, while more than one Source Ports can be
existed. When a port is configured as mirroring port, its corresponding port can
’t be
configured as source port.
