Chapter 2 Introduction
Thanks for choosing the TL-SL3428 24-Port 10/100Mbps + 4-Port Gigabit L2 Managed Switch!
2.1 Overview of the Switch
Designed for workgroups and departments, TL-SL3428 from TP-Link provides wire-speed
performance and full set of layer 2 management features. It provides a variety of service features
and multiple powerful functions with high security.
The EIA-standardized framework and smart configuration capacity can provide flexible solutions
for a variable scale of networks. ACL, 802.1x and Dynamic ARP Inspection provide robust security
strategy. QoS and IGMP snooping/filtering optimize voice and video application. Link aggregation
(LACP) increases aggregated bandwidth, optimizing the transport of business critical data. SNMP,
RMON, WEB/CLI/Telnet Log-in bring abundant management policies. TL-SL3428 Switch
integrates multiple functions with excellent performance, and is friendly to manage, which can fully
meet the need of the users demanding higher networking performance.
2.2 Main Features
Resiliency and Availability
+ Link aggregation (LACP) increases aggregated bandwidth, optimizing the transport of
business critical data.
+ IEEE 802.1s Multiple Spanning Tree provides high link availability in multiple VLAN
environments.
+ Multicast snooping automatically prevents flooding of IP multicast traffic.
+ Root Guard protects root bridge from malicious attack or configuration mistakes
Layer 2 Switching
+ GVRP (GARP VLAN Registration Protocol) allows automatic learning and dynamic
assignment of VLANs.
+ Supports 255 active VLAN groups and 4K VLAN IDs.
Quality of Service
+ Supports L2/L3 granular CoS with 4 priority queues per port.
+ Rate limiting confines the traffic flow accurately according to the preset value.
Security
+ Supports multiple industry standard user authentication methods such as 802.1x, RADIUS.
+ Dynamic ARP Inspection blocks ARP packets from unauthorized hosts, preventing
man-in-the-middle attacks.
+ L2/L3/L4 Access Control Lists restrict untrusted access to the protected resource.
+ Provides SSHv1/v2, SSL 2.0/3.0 and TLS v1 for access encryption.
Manageability
+ IP Clustering provides high scalability and easy Single-IP-Management.
+ Supports Telnet, CLI, SNMP v1/v2c/v3, RMON and web access.
+ Port Mirroring enables monitoring selected ingress/egress traffic.

2.3.1 Front Panel
Figure 2-1 Front Panel
The following parts are located on the front panel of the Switch:
10/100Mbps Ports: Designed to connect to the device with a bandwidth of 10Mbps or
100Mbps. Each has a corresponding 10/100Mbps LED.
10/100/1000Mbps Ports: Designed to connect to the device with a bandwidth of 10Mbps,
100Mbps or 1000Mbps. Each has a corresponding 1000Mbps LED.
SFP Ports: Designed to install the SFP module. The Switch features some SFP transceiver
slots that are shared with the associated RJ45 ports. The associated two ports are referred as a
“Combo” port, which means they cannot be used simultaneously, otherwise only SFP port
works.
Console Port: Designed to connect with the serial port of a computer or terminal for monitoring
and configuring the Switch.

4.1.4 System IP
Each device in the network possesses a unique IP Address. You can log on to the Web
management page to operate the switch using this IP Address. The switch supports three modes
to obtain an IP address: Static IP, DHCP and BOOTP. The IP address obtained using a new mode
will replace the original IP address. On this page you can configure the system IP of the switch.
Choose the menu System→System Info→System IP to load the following page.
Figure 4-6 System IP
The following entries are displayed on this screen:
IP Config
MAC Address: Displays MAC Address of the switch.

IP
Address Mode: Select the mode to obtain IP Address for the switch.
Static IP: When this option is selected, you should enter IP
Address, Subnet Mask and Default Gateway manually.
DHCP: When this option is selected, the switch will obtain
network parameters from the DHCP Server.
BOOTP: When this option is selected, the switch will obtain
network parameters from the BOOTP Server.
Management VLAN: Enter the ID of management VLAN, the only VLAN through which
you can get access to the switch. By default VLAN1 owning all the
ports is the Management VLAN and you can access the switch via
any port on the switch. However, if another VLAN is created and
set to be the Management VLAN, you may have to reconnect the
management station to a port that is a member of the
Management VLAN.
IP Address: Enter the system IP of the switch. The default system IP is
192.168.0.1 and you can change it appropriate to your needs.
Subnet Mask: Enter the subnet mask of the switch.
Default Gateway: Enter the default gateway of the switch.
Note:
1. Changing the IP address to a different IP segment will interrupt the network communication,
so please keep the new IP address in the same IP segment with the local network.
2. The switch only possesses an IP address. The IP address configured will replace the original
IP address.
3. If the switch gets the IP address from DHCP server, you can see the configuration of the
switch in the DHCP server; if DHCP option is selected but no DHCP server exists in the
network, the switch will keep obtaining IP address from DHCP server until success.
4. If DHCP or BOOTP option is selected, the switch will gets network parameters dynamically
from the Internet, so IP address, subnet mask and default gateway can not be configured.
5. By default, the default IP address is 192.168.0.1.

4.4.2 SSL Config
SSL (Secure Sockets Layer), a security protocol, is to provide a secure connection for the
application layer protocol (e.g. HTTP) communication based on TCP. SSL is widely used to secure
the data transmission between the Web browser and servers. It is mainly applied through
ecommerce and online banking.
SSL mainly provides the following services:
1. Authenticate the users and the servers based on the certificates to ensure the data are
transmitted to the correct users and servers;
2. Encrypt the data transmission to prevent the data being intercepted;
3. Maintain the integrality of the data to prevent the data being altered in the transmission.
Adopting asymmetrical encryption technology, SSL uses key pair to encrypt/decrypt information. A
key pair refers to a public key (contained in the certificate) and its corresponding private key. By
default the switch has a certificate (self-signed certificate) and a corresponding private key. The
Certificate/Key Download function enables the user to replace the default key pair.
After SSL is effective, you can log on to the Web management page via https://192.168.0.1
. For
the first time you use HTTPS connection to log into the switch with the default certificate, you will
be prompted that “The security certificate presented by this website was not issued by a trusted
certificate authority” or “Certificate Errors”. Please add this certificate to trusted certificates or
continue to this website.
On this page you can configure the SSL function.
Choose the menu System→Access Security→SSL Config to load the following page.
