Port Mirroring Configuration
Port monitoring is a feature to redirect the traffic occurred on every port to a
designated monitoring port on the switch. With this feature, the network
administrator can monitor and analyze the traffic on the entire LAN segment. In the
Managed Switch, you can specify one port to be the monitored ports and any single
port to be the monitoring port. You also can specify the direction of the traffic that
you want to monitor. After properly configured, packets with the specified direction
from the monitored ports are forwarded to the monitoring port.
NOTE: The default Port Monitoring setting is disabled.
