CHAPTER 48
MAC Table
This chapter introduces the MAC Table.
48.1 Introduction to MAC Table
The MAC table lists device MAC addresses that are dynamically learned by the VES-1616FE-
55A. The table shows the following for each MAC address: the port upon which Ethernet
frames were received from the device, to which VLAN groups the device belongs (if any) and
to which channel it is connected (for devices connected to DSL ports).
The device uses the MAC table to determine how to forward frames. See the following figure.
Figure 159 MAC Table Filtering Flowchart
1 The device examines a received frame and learns the port on which this source MAC
address came.
2 The device checks to see if the frame's destination MAC address matches a source MAC
address already learned in the MAC table.
If the device has already learned the port for this MAC address, then it forwards the frame
to that port.
