9. These processes may be used individually or in tandem The first process the IEEE 802 1D filtering process begins with the creation of a list of local node addresses in a table the SAT When the 9T122 08 first goes on line it initially forwards all packets across the bridge After receiving a packet on the bridge port the 9T122 08 learns the address of the sending node from the packet and stores that address in the SAT In this manner the bridge learns the address of each node on each side of the bridge The bridge then uses the addresses stored in the table to compare the destination address of each subsequent packet that travels to the bridge If the destination address of a packet resides on the bridge segment the 9T122 08 does not forward across the Token Ring link The second filtering process the Cabletron Systems Special Filtering Database provides an additional step in the filter forward decision Through Remote Management you can define up to 10 additional filtering parameters for incoming network traffic These parameters include but are not limited to the Destination address Source address Type field protocol 64 bytes of the data field using a data offset For example using this process you can ensure that the 9T122 08 always filters or forwards packets with a specific protocol or address Operation Source Route Bridging Provided Only Between Front Panel Rings Source Route Bridging operates by transm
