MAC Management
Dynamic Address:
The MAC addresses are learnt by the switch. When the switch receives frames, it will
record the source MAC, the received port and the VLAN in the address table with an age
time. When the age time is expired, the address entry will be removed from the address
table.
Static Address:
The MAC addresses are configured by users. The static addresses will not be aged out by
the switch; it can be removed by user only. The maximum static address entry is up to
256.
The MAC Table (a MAC table is also known as a filtering database) shows how frames are
forwarded or filtered across the Switch’s ports. When a device (which may belong to a
VLAN group) sends a packet which is forwarded to a port on the Switch, the MAC address
of the device is shown on the Switch’s MAC Table. It also shows whether the MAC address
is dynamic (learned by the Switch) or static (manually entered).
The Switch uses the MAC Table to determine how to forward frames. See the following
figure.
1. The Switch examines the received frame and learns the port from which this
source MAC address came.
2. The Switch checks to see if the frame's destination MAC address matches a
source MAC address already learnt in the MAC Table.
 If the Switch has already learnt the port for this MAC address, then it
forwards the frame to that port.
 If the Switch has not already learnt the port for this MAC address, then
the frame is flooded to all ports. If too much port flooding, it may lead
to network congestion.
 If the Switch has already learnt the port for this MAC address, but the
destination port is the same as the port it came in on, then it filters the
frame.
