Interpreting Data in the Bridging Table (All)
If NAT (network address translation) is not active on the SM, then the Bridging Table tab provides the
MAC address of all devices that are attached to registered SMs (identified by LUIDs). The bridging
table allows data to be sent to the correct module as follows:
For the AP, the uplink is from RF to Ethernet. Thus, when a packet arrives in the RF interface to
the AP, the AP reads the MAC address from the inbound packet and creates a bridging table entry
of the source MAC address on the other end of the RF interface.
For the SM, the uplink is from Ethernet to RF. Thus, when a packet arrives in the Ethernet
interface to one of these modules, the module reads the MAC address from the inbound packet and
creates a bridging table entry of the source MAC address on the other end of the Ethernet interface.
