Port Monitoring Overview
The port monitoring feature allows you to unobtrusively monitor the
traffic being received and transmitted on a port on a switch by having
the traffic copied to another switch port. You can connect a network
analyzer to the port where the traffic is being copied and monitor the
traffic on the other port without impacting network performance or
speed.
Observe the following guidelines when creating a port trunk:
❑ You can monitor only one port on a switch at a time.
❑ The port to be monitored and the monitoring port must be
located on the same switch.
❑ The port to be monitored and the monitoring port must be
operating at the same speed. For example, you cannot use a
10/100 Mbps port to monitor traffic on a 1000 Mbps GBIC port.
