Using Predefined Subtype Filters

You can configure the access point to pass or drop certain predefined frame subtypes.

To configure predefined subtype filters

1. From the main menu, click IP Tunnels and then click Tunnel Filters.

2. Click Predefined Subtype Filters. The Predefined Subtype Filters screen appears.

3. In each frame subtype field, click the down arrow on the right side of the Action

field and choose Pass or Drop.

4. Click Submit Changes to save your changes. To activate your changes, from the

menu bar click Save/Discard Changes and then click Save Changes and Reboot. For
help, see “Saving Configuration Changes” in Chapter 1.
