RADIUS

 

 

 

 

 

To add a RADIUS Server to the RADIUS Table:

STEP 1 Click Add

STEP 2 Enter the parameters:

•RADIUS Server—IP address or hostname of the server.

•Priority—The lower the priority number value, higher the priority of the server. For example, server configured with priority value 1 has higher priority than server configured with priority value 2. If all the servers are configured with the same or the default priority value, the switch tries the RADIUS servers in a first-come, first served basis. The range is 1 to 65535. The default is 8.

•Key String—A shared secret text string used for authenticating and encrypting all RADIUS communications between the switch and the RADIUS server. This secret must match the secret configured on the RADIUS server. This must be an ASCII alphanumeric value between 32 to 176 characters.

•Authentication Port—Port number used for RADIUS authentication requests and replies. The default port, 1812, is the well-know IANA port number for RADIUS authentication services. The range is 1025 to 65535. The default is1812.

•Message Authenticator—This field is selected by default. When enabled, the message authenticator attribute is included in RADIUS request messages to the server. This attribute protects the RADIUS messages from spoofing and tampering. The shared secret is used as the key. If the RADIUS Message Authenticator attribute is present in the packet, it is verified by the server. If verification fails, the server drops the request packet.

STEP 3 Click Apply and then click Close. Your changes are saved to the Running Configuration.

SLM2008PTNA specifications

Cisco Systems SLM2008PTNA is a robust network switch designed specifically for small to medium-sized businesses. It operates with 8 Fast Ethernet ports, providing advanced features and best-in-class performance to enhance your network infrastructure. This model ensures seamless connectivity for multiple devices, making it an ideal choice for environments requiring reliable network communication.

One of the standout features of the SLM2008PTNA is its Layer 2 switching capabilities. This switch supports auto-negotiation, which allows each port to automatically detect the speed of the connected device and adjust accordingly. This ensures optimal performance and smooth operation across various connected devices. Additionally, the switch supports a non-blocking architecture, ensuring that bandwidth is not shared, which significantly enhances data transmission speed.

Power over Ethernet (PoE) is another key technology incorporated into the Cisco SLM2008PTNA. It simplifies the installation of network devices such as VoIP phones, security cameras, and wireless access points by supplying power through the Ethernet cable. This eliminates the need for separate power sources, reducing installation costs and increasing flexibility in device placement.

Moreover, the SLM2008PTNA comes equipped with advanced security features, such as port security and VLAN support. Port security allows network administrators to restrict access to the network based on MAC addresses, preventing unauthorized access and enhancing network security. The support for Virtual Local Area Networks (VLANs) enables the segmentation of the network into different logical networks, improving traffic management and security within each segment.

The switch is designed for easy management and monitoring, featuring a user-friendly web interface that simplifies configuration. This allows network administrators to quickly set up and manage the device without requiring extensive technical knowledge. Additionally, its compact design makes it suitable for desktop or rack-mount installation, maximizing space efficiency in network environments.

In conclusion, the Cisco Systems SLM2008PTNA is an essential component for small to medium-sized businesses looking to enhance their network performance. With its Layer 2 switching capabilities, Power over Ethernet support, advanced security features, and ease of management, this switch provides a well-rounded solution for modern networking needs, delivering reliable performance and scalability for growth.
