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
IES-1248-51V. 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.
