Chapter 7 Configuring the Switch Ports

Configuring SPAN

You can use Switch Port Analyzer (SPAN) to monitor traffic on a given port by forwarding incoming

and outgoing traffic on the port to another port in the same VLAN. A SPAN port cannot monitor ports

in a different VLAN, and a SPAN port must be a static-access port. You can define any number of ports

as SPAN ports, and any combination of ports can be monitored.

For the restrictions that apply to SPAN ports, see the “Avoiding Configuration Conflicts” section on

page 9-2.
