Ethertype filters prevent or allow the use of specific L3 protocols through the access point's Ethernet and radio ports. You can apply the filters you create to either or both the Ethernet and radio ports and to either or both incoming and outgoing packets.
Create/Edit Filter Index
If you are creating a new filter, make sure <NEW> (the default) is selected in the Create/Edit Filter Index menu. To edit an existing filter, select the filter number from the Create/Edit Filter Index menu.
Filter Index
Name the filter with a number from 200 to 299. The number you assign creates an access control list (ACL) for the filter.
Add Ethertype
Enter an Ethertype number.
Mask
Enter the mask for the Ethertype.
Action
Select Forward or Block to determine how the protocol traffic is handled. Click Add. The Ethertype appears in the Filters Classes field.
Default Action
Packets that do not match any of the Filters Classes are handled according to the Default Action.
Select Forward All or Block All from the Default Action menu. The filter's default action must be opposite of the action for at least one of the Ethertypes in the filter. For example, if you enter several Ethertypes and you select Block as the action for all of them, you must choose Forward All as the filter's default action.
When you click Apply, the filter is saved on the access point, but it is not enabled until you apply it on the Apply Filters page.
Filters Classes
Displays the current list of filters. Select the filters you want to delete from the index and click Delete.
