2.9.2. Forwarding Tables

The 709 Setup Page also allows the direct setting of the 709.1 subnet and group forwarding
tables. This is most useful in manual mode or in situations where a special configuration is
needed. The forwarding table portions of the page are shown below.
When the Side A interface is shown, the Side A table is used to determine if packets received on
the Side A should be forwarded across and transmitted out the Side B. Likewise when the Side B
interface is shown, the Side B Table is used to determine if packets received on Side B should be
forwarded across and transmitted out Side A.
For each table the bits are displayed from left to right in increasing order of bit position. Bit
position one refers to subnet number one and so forth. Clicking on a bit will toggle the bit value
and store the new value in memory. A value of one in a bit position means forward, to the
other side of the router, packets addressed to the corresponding subnet or group. A value of
zero in a bit position means do not forward, to the other side of the router, packets addressed
to the corresponding subnet or group.
For example, a 1 in the subnet table on Side A means forward to side B any packets received on
Side A that are addressed to the corresponding subnet. A 0 in the subnet table on Side A means
do not forward any packets to side B that are addressed to the corresponding subnet, likewise
for the group table.
Clear Subnet Table: This button clears all the subnet bits by assigning each a value of zero and
stores the new values in memory.
Set Subnet Table: This button sets all the subnet bits by assigning each a value of one and
stores the new values in memory.
Clear Group Table: This button clears all the group bits by assigning each a value of zero and
stores the new values in memory.
