Description: Like typical legacy bridge devices, FDB table records the mapping of Source MAC Address and its associated source port, and forward incoming packets to its destination port according to the Destination MAC Address of the packet as well as the MAC-port pair entries of the FDB table. Note that the priority of FDB table entries is lower than Filtering Table, i.e. if there is a table hash collision between the entries of FDB Table and Filtering Table inside the switch H/W address table, then Filtering Table entry overwrite the colliding entry of FDB Table. See swFdbFilterTable description also.
