2.Use the SPACE bar or BACKSPACE key to step through the available port selections.

3.Use the arrow keys to highlight the Filter Using VLAN List field.

4.Use the SPACE bar or BACKSPACE key to toggle between YES and NO. When set to YES, the switch will drop all incoming frames that are classified with a VLAN tag of a VLAN that does not appear on the Port VLAN List. The default is NO.

5.Use the arrow keys to highlight the Filter All Untagged Frames field.

6.Use the SPACE bar or BACKSPACE key to toggle between YES or NO. When set to YES, the switch will drop all incoming frames that do not have a VLAN tag header. The default is NO.

7.To save the settings, Use the arrow keys to highlight the SAVE command at the bottom of the screen.

8.Press ENTER. The message “SAVED OK” displays. The settings are saved.
