14.1 Configuring Port Mirroring
Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from one port to a
monitoring port. Port mirroring can be used as a diagnostic tool as well as a debugging feature. Port mirroring also enables
switch performance monitoring.
Network administrators can configure port mirroring by selecting a specific port from which to copy all packets, and other
ports to which the packets copied.
To perform port mirroring diagnostics:
1. Click
System > Maintenance > Diagnostics > Port Mirroring. The Port Mirroring Page opens:
