If the Restricted Bridge Mode is selected, packets will be discarded unless overridden by a user-
defined bridge filter. The bridge filters, therefore, allow you to transfer only the packets that you
specify.
If the Restricted Bridge Mode is selected, the following packet forwarding possibilities exist:
•
If the packet matches a discard filter (packet filter only), it is discarded.
•
If the packet matches a forward filter, it is forwarded to the distribution list.
•
If the packet matches a connect filter, it is connected to the members of the distribution list.
However, with Restricted Mode, the packet needs to match a forwarding filter in order to be
forwarded.
•
If the packet matches no filter, the specific action for the packet depends upon whether or not
the destination is known. (See following descriptions.)
No Filter Match - Destination Known
If the destination is known and the corresponding device is on the Known Connect list, the con-
nection is made. If the device is not on the Known Connect list, the packet is discarded.
No Filter Match - Destination Unknown
The packet is discarded.
