Introduces the guide structure and conventions.
Chapter 2 Introduction Introduces the features, application and appearance of the
switch.
Chapter 3 Login to the Switch
Introduces how to log on to the Web management page.
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 different security measures for the
user to enhance the configuration management security.

SDM Template: Manage the hardware TCAM resources.
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.
Auto Copy Software: Configure
the Auto Copy Software
function.
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.


Chapter
Introduction
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 netw
orks 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 campus or enterprise networks to achieve user layer-2-
separation and to save VLAN resources of uplink devices.

Chapter 2 Introduction
2.1 Overview of the Switch
T3700G-28TQ/T3700G-52TQ is an L3 managed switch that features advanced L3 routing,
10Gbps wire-speed, physical stacking and removable power supply module and fan module,
designed to meet the needs of convergence layer. T3700G-28TQ/T3700G-52TQ is ideal for
large businesses, campuses or SMB networks requiring an outstanding, reliable and affordable
10 Gigabit solution.
T3700G-28TQ/T3700G-52TQ supports stacking of up to 8 units, thus providing flexible
scalability and protective redundancy for your networks. Moreover, aiming to better protect
