Note:

When moving to and from basic and advanced QoS modes, some settings may be lost.

12.1.2.1 Basic QoS Mode

Basic Mode supports activating one of the following Trust settings:

VLAN Point Tag

DiffServ Code Point

None

In addition, a single IP-based ACL can be attached directly to the interface (see section on network security for more information). Only packets that have a Forward action are assigned to the output queue, based on the specified classification. By properly configuring the output queues, the following basic mode services can be set:

Minimum Delay — The queue is assigned to a strict priority policy, and traffic is assigned to the highest priority queue.

Best Effort — Traffic is assigned to the lowest priority queue

Bandwidth Assignments — Bandwidths are assigned by configuring the WRR scheduling scheme and choosing the right weights.

12.1.2.2 Advanced QoS Mode

Advanced QoS mode provides rules for specifying flow classification and assigning rule actions that relate to bandwidth management.

After assigning packets to a specific queue, services such as configuring output queues for the scheduling scheme, or configuring output shaping for burst size, CIR, or CBS per interface or per queue, can be applied. In Advanced Mode packets may egress with a different VPT tag than expected.

12.2 Enabling Quality of Service

This section contains the following topics:

Enabling Quality of Service

Mapping Queues

12.2.1 Enabling Quality of Service

The CoS Settings Page contains fields for enabling or disabling QoS. In addition, the Trust mode can be selected. The Trust mode relies on predefined fields within the packet to determine the egress queue settings.

To enable QoS and define basic settings:

TL-SG3109, TL-SL3428, TL-SL3452 specifications

The TP-Link TL-SL3428 is a feature-rich Ethernet switch designed for small to medium-sized business environments. It is part of TP-Link’s JetStream series, which emphasizes reliability, performance, and robust management capabilities. Built with 28 10/100/1000 Mbps ports, the TL-SL3428 provides sufficient bandwidth to support a wide range of network applications.

One of the standout features of the TL-SL3428 is its support for Layer 2 management protocols. This allows for more granular control and optimized performance across network segments. The switch supports VLAN (Virtual Local Area Network) segmentation, which enhances network security and efficiency by isolating various types of traffic. This feature is particularly useful in larger organizations where different departments or teams may require separate network environments.

The TL-SL3428 also includes advanced QoS (Quality of Service) capabilities. This functionality prioritizes traffic based on predefined rules, which ensures that critical applications receive the necessary bandwidth to function optimally. With QoS implementation, users can experience minimized latency, leading to better performance in VoIP and video conferencing applications.

In terms of redundancy and reliability, the switch also supports Link Aggregation Control Protocol (LACP), enabling multiple connections to be combined for increased bandwidth and failover support. This feature significantly enhances network resilience, ensuring minimal downtime during failures.

Power over Ethernet (PoE) support is another important characteristic of the TL-SL3428. With PoE capabilities, this switch can deliver electrical power along with data over the same Ethernet cable, simplifying installation and reducing the need for additional wiring. This is especially advantageous for IP devices like cameras, access points, and VoIP phones.

Security features are abundant in the TL-SL3428 as well. It implements port security, storm control, and DHCP snooping, all of which contribute to a secure network infrastructure. The switch’s management capabilities can be accessed through a user-friendly web interface, making it easier for IT administrators to configure and monitor network activities.

Overall, the TP-Link TL-SL3428 is an exemplary choice for businesses looking to enhance their network performance with advanced management features, security protocols, and reliability. Its combination of speed, flexibility, and manageability make it a valuable tool for any growing organization.
