24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet

Information

You can display a summary of the current bridge STA information that applies to the entire switch using the Information screen.

This screen displays the following information.

Spanning Tree State. Shows if the switch is enabled to participate in an STA-compliant network.

Designated Root. The priority and MAC address of the device in the Spanning Tree that this switch has accepted as the root device.

Bridge ID. A unique identifier for this bridge, consisting of the bridge priority and MAC address (where the address is taken from the switch system).

Root Port. The number of the port on this switch that is closest to the root. This switch communicates with the root device through this port. If there is no root port, then this switch has been accepted as the root device of the Spanning Tree network.

Max Age. The maximum time (in seconds) a device can wait without receiving a configuration message before attempting to reconfigure. All device ports (except for designated ports) should receive configuration messages at regular intervals. Any port that ages out STA information (provided in the last configuration message) becomes the designated port for the attached LAN. If it is a root port, a new root port is selected from among the device ports attached to the network. (References to “ports” in this section mean “interfaces,” which includes both ports and lags.)

Root Path Cost. The path cost from the root port on this switch to the root device.

Hello Time. Interval (in seconds) at which this device transmits a configuration message.

Configuration Changes. The number of times the Spanning Tree has been reconfigured.

Forward Delay. The maximum time (in seconds) the root device will wait before changing states (i.e., discarding to learning to forwarding). This delay is required because every device must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to a discarding state; otherwise, temporary data loops might result.

Last Topology Change. Time since the Spanning Tree was last reconfigured.

SRW224P specifications

The Linksys SRW224P is a versatile and efficient managed switch that caters to the needs of small to medium-sized businesses. This Layer 2 switch stands out with its robust functionality and user-friendly design, making it an ideal choice for networking professionals looking to enhance their network infrastructure.

One of the standout features of the SRW224P is its 24 Gigabit Ethernet ports, which provide high-speed connectivity for various devices across the network. This is particularly beneficial in environments with bandwidth-hungry applications, such as data transfers, video conferencing, and online collaboration tools. Additionally, the switch comes with 2 dual-personality ports that can be used as either Gigabit Ethernet or SFP (Small Form-factor Pluggable) ports, allowing for flexible and scalable network setups.

Power over Ethernet (PoE) capability is another significant aspect of the SRW224P. With a total PoE output of up to 370 watts, the switch can power devices such as IP cameras, VoIP phones, and wireless access points directly through the Ethernet cable, simplifying the installation process and reducing cable clutter. This feature is particularly advantageous for organizations seeking to deploy network devices in areas where power outlets are limited.

The SRW224P also boasts advanced management features, including VLAN support for segmenting network traffic, Quality of Service (QoS) for prioritizing critical applications, and Spanning Tree Protocol (STP) for redundant network paths. These capabilities enhance network performance and reliability, ensuring that users experience minimal downtime and efficient data flow.

Security is a top priority with the SRW224P, which includes features such as port security, access control lists (ACLs), and DHCP snooping. These measures help protect the network from unauthorized access and potential attacks, safeguarding sensitive information and maintaining operational integrity.

In terms of user interface, the Linksys SRW224P is equipped with a web-based management interface that allows for easy configuration and monitoring. This intuitive interface enables IT administrators to manage the switch remotely, providing real-time insights into network performance and facilitating troubleshooting.

Overall, the Linksys SRW224P managed switch combines high performance, advanced features, and security measures that make it a reliable choice for businesses aiming to optimize their network infrastructure. Its PoE capabilities, extensive port options, and management features ensure that it meets the demands of modern networking environments, making it a valuable asset for any organization.
