Chapter Introduction
Chapter 4 System This module is used to configure system properties of the switch.
Here mainly introduces:

System Info: Configure the description, system time and
network parameters of the switch.
User Management: Configure the user name and password for
users to manage the switch with a certain access level.
System Tools: Manage the configuration file of the switch.
Access Security: Provide diffe
rent security measures for the
user to enhance the configuration management security.
Chapter 5 Stack This module
is used to configure the stack properties of the
switch. Here mainly introduces:
Stack Info: View the detailed information of the stack.
Stack Config: Configure the current stack.
Switch Renumber: Configure the stack member’s unit ID.
Chapter 6 Switching
This module is used to configure basic functions of the switch.
Here mainly introduces:
Port: Configure the basic features for the port.

LAG: Configure Link Aggregation Group. LAG is to combine a
number of ports together to make a single high-bandwidth data
path.
Traffic Monitor: Monitor the traffic of each port
MAC Address: Configure the address table of the switch.
Chapter 7 VLAN
This module is used to configure VLANs to control broadcast in
LANs. Here mainly introduces:
802.1Q VLAN: Configure port-based VLAN.
MAC VLAN: Configure MAC-
based VLAN without changing
the 802.1Q VLAN configuration.

Protocol VLAN: Create VLANs in application layer to make
some special data transmitted in the specified VLAN.

VLAN VPN: VLAN VPN allows the packets with VLAN tags of
private networks to be encapsulated with VLAN tags of public
networks at the network access terminal of the Internet Service
Provider.
GVRP: GVRP allows the switch to automatically add or remove
the VLANs via the dynamic VLAN registration information and
propagate the local VLAN registration information to other
switches, without having to individually configure each VLAN.
Private VLAN:
Designed to save VLAN resources of uplink
devices and decrease broadcast. Private VLAN mainly used in
