7.1.3

Management Host

The management host limits the number of hosts that the switch can manage.
There is no "Management Host" in the default settings. Any host can manage the
switch via Telnet or web browser. If a user has configured one or more hosts, only
those hosts can manage the switch. The function allows users to configure up to
three entries for the management IPs.
7.1.4

MAC Management

The MAC address ("Media Access Control") is the unique hardware number in a
network.
Dynamic Address
When receiving frames, the switch records the source MAC address, receiving
port, VLAN and an "Age Time" in the address table. When the "Age Time" is
expired, the address entry is deleted from the address table.
Static Address
A static address set by the user does not include the "age time" and is not deleted
by the switch. The static address can only be deleted by a user. The switch
supports an address table at up to 16 K.
Static and dynamic addresses share the same address table.
MAC Table
The "MAC Table" (MAC address table, also known as a filter database) shows
which frames are forwarded to the switch's ports or which frames are filtered out.
If a device that belongs to a VLAN group sends a data packet that is forwarded to
a port on the switch, the MAC address of the device is read from the switch's
MAC address table.
It also shows whether the MAC address is dynamic (assigned by the switch) or
static (set manually).
MAC Address Table
The switch uses the MAC address table to determine how to forward frames (see
figure below).
1. The switch checks a received frame and detects the port from which the
MAC source address originates.
2. The switch checks if the frame's destination MAC address matches a source
MAC address already detected in the MAC address table.
• If the switch already knows the port for this MAC address, the it
forwards the frame to that port.
