5.13.1 Mirror
Port mirroring refers to copy data from the port which need to be monitored to appointed monitoring port
for analysis and monitoring. Ethernet switch supports many-for-one mirror which means messages from
several ports can be copied to a monitored port. User can appoint the direction of monitored message,
such as only monitoring of transmitted messages of appointed port. The device configures port mirroring
function through port mirroring group. Each group includes a monitored port and a group of mirror ports.
Total bandwidth of mirroring is not more than that of monitored port. It is good to monitor and manage its
internal network data when using port mirroring in a company. It is also good to locate the failure when
network is cut up.
Example as figure: Port 3 collect all of the data from port 1 and port 2
