Advanced Configuration

Use the Setting Timer button to open the Setting Timer screen to configure ports for 802.1x functionality.

802.1x Settings > Setting Timer

802.1x Settings > Setting Timer

Port  Indicates the port name.

Reauthentication Period  Specifies the number of seconds in which the selected port is reauthenticated (Range: 300–4,294,967,295). The field default is 3600 seconds.

Quiet Period  Specifies the number of seconds that the switch remains in the quiet state following a failed authentication exchange (Range: 0–65,535).

Resending EAP  Specifies the number of seconds that the switch waits for a response to an EAP - request/identity frame, from the supplicant (client), before resending the request.

Max EAP Requests  Displays the total amount of EAP requests sent. If a response is not received after the defined period, the authentication process is restarted. The field default is 2 retries.

SupplicantTimeout  Displays the number of seconds that lapses before EAP requests are resent to the supplicant (Range: 1–65,535). The field default is 30 seconds.

Server Timeout  Specifies the number of seconds (1–65,535) that lapses before the switch resends a request to the authentication server. The default is 30 seconds.

Security > Port Security

Network security can be increased by limiting access on a specific port only to users with specific MAC addresses. MAC addresses can be dynamically learned or statically configured. Locked port security monitors both received and learned packets that are received on specific ports. Access to the locked port is limited to users with specific MAC addresses. These addresses are either manually defined on the port, or learned on that port up to the point when it is locked. When a packet is received on a locked port, and the packet source MAC address is not tied to that port (either it was learned on a different port, or it is unknown to the system), the protection mechanism is invoked, and can provide various options. Unauthorized packets arriving at a locked port are either:

•• Forwarded

•• Discarded with no trap

•• Discarded with a trap

•• Cause the port to be shut down.

Locked port security also enables storing a list of MAC addresses in the configuration file. The MAC address list can be restored after the device has been reset.

Disabled ports are activated from the Port Security page.

Interface  Displays the port or LAG name.

Lock Interface  Selecting this option locks the specified interface.

The Linksys SRW2048 is a robust Layer 2 managed switch that caters to the networking needs of small to medium-sized businesses. Designed with performance and reliability in mind, it provides features that ensure optimal network efficiency and security.

One of the standout features of the SRW2048 is its 48 10/100/1000 Mbps Gigabit Ethernet ports, enabling high-speed data transfer and seamless connectivity for various devices within the network. This makes it ideal for environments with heavy data traffic, ensuring minimal latency and high performance.

The SRW2048 also supports advanced Layer 2 management features, including VLAN (Virtual Local Area Network) support, which allows users to segment the network into smaller, manageable sections. This is crucial for improving security and performance, as it reduces unnecessary traffic and potential broadcast storms. With a VLAN configuration, businesses can group users and devices based on function or department, ensuring efficient communication within teams.

In addition to VLAN capabilities, the Linksys SRW2048 incorporates Quality of Service (QoS) features. This technology prioritizes critical network traffic, such as voice over IP (VoIP) and video conferencing, ensuring that these applications receive the bandwidth they require for optimal performance. This is particularly beneficial for businesses that rely on real-time communication tools.

The switch also enhances security through features such as IEEE 802.1X port security, which ensures that only authorized users can access the network. The SRW2048 supports access control lists (ACLs), allowing administrators to set specific permissions for users and devices, further tightening security.

Linksys has also equipped the SRW2048 with a user-friendly web-based management interface, simplifying the process of configuring and monitoring network performance. This accessible interface allows IT personnel to quickly identify issues, manage traffic, and configure settings without extensive training.

Another notable characteristic of the Linksys SRW2048 is its robust build quality and reliability. With a metal chassis and fanless design, it maintains a low acoustic footprint and ensures passive cooling, making it suitable for office environments.

Overall, the Linksys SRW2048 is a feature-rich managed switch that combines advanced networking technologies, efficient performance, and security features to meet the diverse needs of modern businesses. Its scalability, manageability, and robust construction make it a valuable addition to any network infrastructure.
