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

This Switch uses the Extensible Authentication Protocol over LANs (EAPOL) to exchange authentication protocol messages with the client, and a remote RADIUS authentication server to verify user identity and access rights. When a client (i.e., Supplicant) connects to a switch port, the switch (i.e., Authenticator) responds with an EAPOL identity request. The client provides its identity (such as a user name) in an EAPOL response to the switch, which it forwards to the RADIUS server. The RADIUS server verifies the client identity and sends an access challenge back to the client. The EAP packet from the RADIUS server contains not only the challenge, but the authentication method to be used. The client can reject the authentication method and request another, depending on the configuration of the client software and the RADIUS server. The authentication method must be MD5. The client responds to the appropriate method with its credentials, such as a password or certificate. The RADIUS server verifies the client credentials and responds with an accept or reject packet. If authentication is successful, the switch allows the client to access the network. Otherwise, network access is denied and the port remains blocked.

The operation of 802.1X on the switch requires the following:

The switch must have an IP address assigned.

RADIUS authentication must be enabled on the switch and the IP address of the RADIUS server specified.

802.1X must be enabled globally for the switch.

Each switch port that will be used must be set to dot1X “Auto” mode.

Each client that needs to be authenticated must have dot1X client software installed and properly configured.

The RADIUS server and 802.1X client support EAP. (The switch only supports EAPOL in order to pass the EAP packets from the server to the client.)

The RADIUS server and client also have to support the same EAP authentication type – MD5. (Some clients have native support in Windows, otherwise the dot1x client must support it.)

To enable 802.1X System Authentication Control, mark the Enable checkbox.

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.
