the restricted bridge mode.
Unrestricted Mode Bridge Filters
1. SOURCE unicast-address DISCARD < distribution list >
This filter allows you to restrict the access privileges of a given device. When the specified
unicast address appears in the source address field of a MAC frame, the frame will NOT be
forwarded as specified in the distribution list. If no distribution list is specified, the frame will
not be forwarded at all. In this manner, you can specify remote sites and LANs to which the
device cannot talk.
2. SOURCE unicast-address CONNECT < distribution list >
This filter allows you to stipulate access privileges of a given device. When the specified unicast
address appears in the source address field of a MAC frame, the frame will be connected and
forwarded as specified in the distribution list. In this manner, you can specify remote sites and
LANs for connection.
3. DESTINATION MAC-address DISCARD < distribution list >
This filter allows you to discard MAC frames addressed to the specified MAC address. When
the specified MAC address appears in the destination address field of the MAC frame, the
frame will NOT be forwarded as specified in the distribution list. If no distribution list is
specified, the frame will not be forwarded.
