Port Mirroring
Port mirroring is for advanced users with experience in troubleshooting traffic
and protocol issues on networks.
The port mirroring feature copies (or mirrors) traffic on one port to a
monitoring port where the packet can be captured by a network protocol
analyzer tool. Use port mirroring as a diagnostic tool or debugging feature.
Port mirroring does not affect the switching of network traffic on the
monitored port. You must dedicate a monitoring port for port mirroring use.
Except for traffic that is being copied for the port mirroring session, the
monitoring port does not receive or forward traffic.
Port mirroring can be configured by assigning the Port Mirroring Smartports
role on a switch port by using the Device Manager Web interface (see Chapter
3, Manage the Switch via the Device Manager Web Interface ).
