Selecting the Type of Filtering for a Port

A port can be set to filter out received frames according to its Port VLAN List. This keeps them
from being transmitted and drops all untagged frames from being transmitted. To set this type of
filtering, proceed as follows:

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 Lists 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.

screen.
