The Protected Ports feature assists in Layer 2 security. Ports that are configured to be protected cannot forward traffic to other protected ports in the same group, regardless of having the same VLAN membership. However, protected ports can forward traffic to ports which are unprotected as well as ports in other protected groups. Unprotected ports can forward traffic to both protected and unprotected ports.
Use the Protected Ports Configuration page to create up to three protected port groups and to assign physical ports to a group. To display the Protected Port Configuration page, click Switching > Protected Ports > Configuration in the navigation menu.
