Port Mirroring
Port Mirroring
Port mirroring sends a copy of all packets sent and/or received on one port (the source port) to another
port (the destination port) for monitoring and analysis by an external network analyzer. Multiple switch
ports can be configured as source ports, with each port mirrored to the same destination. You can also
mirror the internal CPU traffic to an external port for debugging the CPU. No destination port is defined
by default. In its default state, the destination port does not participate in traffic forwarding, and it
cannot be configured to participate in VLANs.
C a u t i o n
■ When configuring port mirroring, avoid oversubscribing the destination port to prevent the
loss of mirrored data.
■ While a port is used as the destination port for mirrored data, the port cannot be used for any
other purpose; the port will not receive and forward traffic.
To display the Port Mirroring page, click Switching > Port Mirroring in the navigation pane.
In the example configuration in Figure 4-3 , port mirroring is configured to mirror TX and RX packets
on Source Port 1 to Destination Port 4.
