Using Filters 11 - 9

You may set up ﬁlters based on either a protocol identiﬁer or a DSAP/

SSAP combination. If the ﬁlter is based on SAPs and the control ﬁeld

has a value of 3, the packet may also be optionally ﬁltered based on the

OUI and LLC protocol ﬁelds.

Both types of ﬁlters may also use a variable length bit mask of the

packet contents to further specify which packets should be ﬁltered.

Setting the Default Action (Default)

The default action is used for a packet whose protocol does not match

any entry found in the table. It may be set to:

n Off: Protocol ﬁltering is not done. It is a waste of processing power

for the unit to examine each packet for its protocol only to discover

no protocols need monitoring.

n Discard: The packet will not be forwarded out the radio network.

n Forward: The packet will be forwarded out the radio network.

n Accesspt: The packet will only be forwarded to other Bridges and

not to the client nodes.

n Nonpsp: The packet will be forwarded out the radio network to non-

power saving end nodes and not to any nodes using PSP.
