TP-LINK TL-T1500G-28TC (TL-SL2428) is a smart Gigabit network switch equipped with 24 Fast Ethernet 10/100 Mbps RJ45 ports, 4 Gigabit Ethernet 10/100/1000 Mbps RJ45 ports and 2 SFP combo slots. The device has extensive network traffic security features, including support for VLAN 802.1Q, and additionally Port Security and Storm Control, which effectively protect our local network. The switch can be managed through a web browser, command line or with SNMP and RMON protocols. In addition, the switch has the ability to optimize voice and video transmissions with QoS (L2/L3/L4) and IGMP Snooping. TL-SL2428 is a cost-effective solution for medium and small businesses.
For better audio, data and video transmission over the network, the device uses the advanced QoS function. The network administrator can set the priorities for network traffic, e.g. for individual IP addresses, MAC addresses, TCP or UDP ports, etc. This ensures that audio and video transmission is smooth, clear and free of transmission delays. In combination with support for dedicated VLANs, this makes voice transmissions smoother and more efficient.
To increase the number of possible applications, TL-SL2428 switches are equipped with a number of second layer traffic management features, including 802.1Q VLAN support, port isolation, port mirroring, STP/RSTP/MSTP, port aggregation and 802.3x flow control. Additionally, it is equipped with numerous maintenance functions such as loop back connection detection, cable diagnostics and IGMP snooping. IGMP snooping allows for intelligent multicast streaming to specific subscribers only, and IGMP throttling and IGMP filtering effectively restricts access to multicast for unauthorized users.
TL-SL2428 is easy to use and manage. The hardware offers many intuitive management options in a user-friendly environment, such as the GUI graphical user interface and CLI command line interface.

Introduction
Voice traffic is usually more time sensitive and may be more affected by packet loss than data traffic. You can configure Voice VLAN to optimize the transmission of voice traffic. Voice VLAN can change the priority of 802.1p voice packets and transmit packets in the desired VLAN.
Network requirements
As shown in the figure below, two IP phones are connected to port 1/0/1 and port 1/0/2 of the switch. The PC is connected to port 1/0/3 of the switch. The switch is connected to the Internet through a router via port 1/0/4. IP phones transmit voice traffic while the computer transmits data traffic. Voice traffic requires higher priority than data traffic.
Configuration diagram
To implement this requirement, you can configure it as follows:
1) Create a VLAN 2 and add port 1/0/1, port 1/0/2 and port 1/0/4 to your VLAN.
2) Configure VLAN 2 as Voice VLAN and set the voice traffic priority to 7.
3) Switch on the Voice VLAN on ports 1/0/1 and 1/0/2.
Configuration steps
For the T2600G-28TS, the following sections describe the configuration procedure.
Step 1
Select the L2 FUNCTIONS> VLAN> 802.1Q VLAN> VLAN Configuration menu and click Add to load the next page. Create a VLAN 2 for voice traffic. Enter the name of the VLAN as Voice_VLAN . There is no need to add ports that are connected to IP phones. Just add the uplink port 1/0/4 to your VLAN 2, for example, set it here as an un-tagged port. Click Create .
Step 2
Select the QoS> Voice VLAN> Global Config menu to load the next page. Enable Voice VLAN globally. Set the VLAN ID to 2 and set the priority to 7 . Click Apply .
Step 3
Select the QoS> Voice VLAN> Config Port menu to load the next page. Enable Voice VLAN on ports 1/0/1 and 1/0/2. Click Apply .
Step 4
Select the QoS> Voice VLAN> OUI Config menu to load the next page. Check the OUI table. Make sure that the OUI address of the voice device is in this table. If the source MAC address of the packet matches the OUI address in the OUI list, the switch identifies the packet as a voice packet and processes it based on the voice VLAN configuration.
