–Rapid STP — Enables Rapid STP on the device.

–Multiple STP — Enables Multiple STP on the device.

BPDU Handling — Determines how BPDU packets are managed when STP is disabled on the port or device. BPDUs are used to transmit spanning tree information. The possible field values are:

–Filtering — Filters BPDU packets when spanning tree is disabled on an interface. This is the default value.

–Flooding — Floods BPDU packets when spanning tree is disabled on an interface.

Path Cost Default Values — Specifies the method used to assign default path cost to STP ports.

The possible field values are:

–Short — Specifies 1 through 65,535 range for port path cost. This is the default value.

–Long — Specifies 1 through 200,000,000 range for port path cost. The default path cost assigned to an interface varies according to the selected method (Hello Time, Max Age, or Forward Delay).

The Bridge Settings section contains the following fields:

Priority (0-65535)— Specifies the bridge priority value. When switches or bridges are running STP, each is assigned a priority. After exchanging BPDUs, the device with the lowest priority value becomes the Root Bridge. The default value is 32768. The port priority value is provided in increments of 4096.

Hello Time (1-10)— Specifies the device Hello Time. The Hello Time indicates the amount of time in seconds a Root Bridge waits between configuration messages. The default is 2 seconds.

Max Age (6-40)— Specifies the device Maximum Age Time. The Maximum Age Time is the amount of time in seconds a bridge waits before sending configuration messages. The default Maximum Age Time is 20 seconds.

Forward Delay (4-30)— Specifies the device Forward Delay Time. The Forward Delay Time is the amount of time in seconds a bridge remains in a listening and learning state before forwarding packets. The default is 15 seconds.

The Designated Port section contains the following fields:

Bridge ID — Identifies the Bridge priority and MAC address.

Root Bridge ID — Identifies the Root Bridge priority and MAC address.

Root Port — Indicates the port number that offers the lowest cost path from this bridge to the Root Bridge. This field is significant when the bridge is not the Root Bridge. The default is zero.

Root Path Cost — The cost of the path from this bridge to the Root Bridge.

Topology Changes Counts — Specifies the total amount of STP state changes that have occurred.

Last Topology Change — Indicates the amount of time that has elapsed since the bridge was initialized or reset, and the last topographic change that occurred. The time is displayed in a day-hour-minute-second format, such as 2 days 5 hours 10 minutes and 4 seconds.

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.
