Advanced Configuration

Learning Mode  Defines the locked port type. The Learning Mode field is enabled only if Locked is selected in the Interface Status field. The possible field values are:

•• Classic Lock  Locks the port using the classic lock mechanism. The port is immediately locked, regardless of the number of addresses that have already been learned.

•• Limited Dynamic Lock  Locks the port by deleting the current dynamic MAC addresses associated with the port. The port learns up to the maximum addresses allowed on the port. Both relearning and aging MAC addresses are enabled.

In order to change the Learning Mode, the Lock Interface must be set to Unlocked. Once the mode is changed, the Lock Interface can be reinstated.

Max Entries  Specifies the number of MAC addresses that can be learned on the port. The Max Entries field is enabled only if Locked is selected in the Interface Status field. In addition, the Limited Dynamic Lock mode is selected. The default is 1.

Action on Violation  Indicates the action to be applied to packets arriving on a locked port. The possible field values are:

•• Discard  Discards packets from any unlearned source. This is the default value.

•• Forward Normal  Forwards packets from an unknown source without learning the MAC address.

•• Discard Disable  Discards packets from any unlearned source and shuts down the port. The port remains shut down until reactivated, or until the device is reset.

Enable Trap  Enables traps when a packet is received on a locked port.

Trap Frequency  The amount of time (in seconds) between traps. The default value is 10 seconds.

Security > Multiple Hosts

The Multiple Hosts screen allows network managers to configure advanced port-based authentication settings for specific ports and VLANs.

Security > Multiple Hosts

Port  Displays the port number for which advanced port- based authentication is enabled.

Enable Multiple Hosts  When checked, indicates that multiple hosts are enabled. Multiple hosts must be enabled in order to either disable the ingress-filter, or to use port-lock security on the selected port.

Action on Violation  Defines the action to be applied to packets arriving in single-host mode, from a host whose MAC address is not the supplicant MAC address. The possible field values are:

•• Discard  Discards the packets. This is the default value.

•• Forward  Forwards the packet.

•• Discard Disable  Discards the packets and shuts down the port. The ports remains shut down until reactivated, or until the device is reset.

Enable Traps  When checked, indicates that traps are enabled for Multiple Hosts.

Trap Frequency  Defines the time period by which traps are sent to the host. The Trap Frequency (1–1,000,000) field can be defined only if multiple hosts are disabled. The default is 10 seconds.

The table contains the following additional fields:

Status  Indicates the host status. If there is an asterisk (*), the port is either not linked or is down. The possible field values are:

Number of Violations  Indicates the number of packets that arrived on the interface in single-host mode, from a host whose MAC address is not the supplicant MAC address.

Linksys SRW2048, SRW248G4, SRW2024, SRW224G4, SRW2016 manual Security Multiple Hosts

SRW2016, SRW224G4, SRW2024, SRW2048, SRW248G4 specifications

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.
