Using Predefined Subtype Filters

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

To configure predefined subtype filters

2.For each frame subtype field, check or clear the check box to configure if the frame subtypes are passed or are dropped. If you check the check box, the frame subtype is allowed to pass.

3.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” on page 46.

Customizing Subtype Filters

You can define output filters that restrict customized frame subtypes that can pass through an IP tunnel. Frames can be filtered by the DIX, 802.2, or 802.3 SNAP type; the IP protocol type; or the TCP or UDP port number. By default, the filters drop all protocol types except the NNL DIX Ethernet type (hexadecimal 875B). Filters must be configured in all root candidates and in any access point that can attach to the remote end of an IP tunnel.

You define the action, subtype, and value parameters in customized filters:

Allow/Pass: Check or clear this check box. Check this check box to pass all frames of the subtype and value. Clear this check box to drop all frames of the subtype and value.
