8 Device Management
This section helps you enhance the switch’s traffic forwarding capacity and manage the
switch efficiently. The following five parts are included:
MAC Binding
: Perform static MAC address binding of the switch ports.
QoS
: Provide different service quality for various network applications according to their
different requirements.
STP
: Eliminate physical loop in data link layer, avoid broadcast storm and provide link
backup redundancy.
IGSP
: Manage and control multicast groups to save network bandwidth, to ensure better
multicast security and to make each host’s separate billing convenient.
SNMP
: Manage the switch efficiently.
8.1 MAC Binding
8.1.1 Overview
MAC binding provides the function of static MAC address table and MAC filtering:
Static MAC address table: After a port is bound with a MAC address, the device that
matches the designated MAC address can access the network only through this port,
not through other ports.
MAC filtering: After a port is bound with a MAC address, this port only allows the device
with the designated MAC address, not other devices to access the network.
Through the MAC binding function, a single port only allows the designated users to use
network resources to ensure network security and user authority and effectively prevent
unauthorized users from gaining data by cheating and performing loiter net.
Tip
Ports whose MAC binding is enabled will automatically disable the address learning
function.
Bound MAC addresses will be manually added and deleted and will not be aged over
time.
