STP Function: To selecting enable or disable STP function on the Switch.

Bridge Priority: This value between 0 and 65535 to specify the priority for forwarding packets. The lower the value, the higher the priority. The default is 32768.

Bridge Max Age: This value may be set to ensure that old information does not endlessly circulate through redundant paths in the network, preventing the effective propagation of the new information. Set by the Root Bridge, this value will aid in determining that the Switch has spanning tree configuration values consistent with other devices on the bridged LAN. If the value ages out and a BPDU has still not been received from the Root Bridge, the Switch will start sending its own BPDU to all other switches for permission to become the Root Bridge. If it turns out that your switch has the lowest Bridge Identifier, it will become the Root Bridge. The user may choose a time between 6 and 40 seconds. The default value is 20.

Bridge Hello Time: The user may set the time interval between transmission of configuration messages by the root device, thus stating that the Switch is still functioning. A time between 1 and 10 seconds may be chosen, with a default setting of 2 seconds.

Bridge Forward Delay: The maximum amount of time (in seconds) that the root device will wait before changing states. The user may choose a time between 4 and 30 seconds. The default is 15 seconds.

Port Path Cost: This defines a metric that indicates the relative cost of forwarding packets to specified port list. The value between 1 and 65535 to determine the cost. The lower the number, the greater the probability the port will be chosen to forward packets. The default value is 10.

DGS-1224T specifications

The D-Link DGS-1224T is a robust and versatile Ethernet switch designed for small to medium-sized businesses that require reliable network performance. With 24 10/100/1000 Mbps Ethernet ports, it provides high-speed connectivity and efficient data transfer rates across the network. This Layer 2 managed switch supports a range of advanced features and technologies that enhance its operational effectiveness and usability.

One of the standout features of the DGS-1224T is its web-based management interface, which allows for easy configuration and monitoring of the switch. This interface provides access to various settings, enabling network administrators to optimize performance according to their specific needs. The switch supports Virtual LANs (VLANs), which help to segregate network traffic for improved security and performance. By creating multiple VLANs, businesses can prioritize traffic and reduce congestion, ensuring that critical applications receive the bandwidth they need.

Additionally, the DGS-1224T includes Quality of Service (QoS) functionalities, which guarantee that voice and video applications maintain high quality through traffic prioritization. This is particularly important for businesses that rely on VoIP and video conferencing solutions, as it ensures minimal latency and jitter.

Power over Ethernet (PoE) support is another significant characteristic of the DGS-1224T. This feature enables the switch to deliver power to compatible devices, such as IP cameras and wireless access points, eliminating the need for separate power supplies and simplifying installation.

The switch also incorporates robust security features, including Access Control Lists (ACLs), which allow administrators to control which devices can access the network. Other security measures include storm control and DHCP snooping to prevent unauthorized access and potential attacks.

In terms of performance, the DGS-1224T supports up to 48 Gbps non-blocking switching capacity, which ensures that the switch can handle heavy traffic without bottlenecks. Its fanless design contributes to quieter operation and makes it suitable for noise-sensitive environments.

Overall, the D-Link DGS-1224T is an excellent choice for businesses looking for a reliable, feature-rich switching solution that can scale with their growing networking needs while ensuring high performance and security.
