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 diagnostic tool and/or a debugging feature. Port mirroring also
enables switch performance monitoring.
Network administrators configure port mirroring by selecting a specific port to
copy all packets, and different ports from which the packets are copied.
To enable port mirroring:
STEP 1 Click Admin > Diagnostics > Port Mirroring. The Port Mirroring Page opens:
Port Mirroring Page
The
Port Mirroring Page contains the following fields:
• Destination Port — Defines the port to which the source port’s traffic is
mirrored.
• Source Port — Defines the port from which traffic is to be analyzed.
