Configuration Using the Web-based Utility

QoS > Queue Settings

The Queue Settings screen is used to define the QoS queue forwarding types.

QoS > Queue Settings

Strict Priority  Indicates that traffic scheduling for the selected queue is based strictly on the queue priority.

WRR  Indicates that traffic scheduling for the selected queue is based strictly on the WRR.

Queue  Displays the queue (1-4) for which the queue settings are displayed.

WRR Weight  Displays the WRR weights to queues.

%of WRR Bandwidth  Displays the percentage of bandwidth assigned to the queue. These values are fixed and cannot be modified.

Click Save Settings to save the changes, or Cancel Changes to cancel the changes.

QoS > DSCP Settings

QoS > DSCP Settings

The DSCP Settings screen allows you to map Differentiated Services Code Point (DSCP) values to specific queues.

DSCP  Indicates the DSCP value in the incoming packet. Select a DSCP value from the drop-down menu to map that value to the associated queue. You can select the DSCP value for the High, Medium, and Normal priority queues. The DSCP values for the Low priority queue are selected automatically based on the other DSCP values.

Queue  The queue (1-4) to which the DSCP value is being mapped.

Click Save Settings to save the changes, or Cancel Changes to cancel the changes.

QoS > Bandwidth

QoS > Bandwidth

The Bandwidth screen allows network managers to define the bandwidth settings for a specified egress or ingress interface. Modifying queue scheduling affects the queue settings globally. The Bandwidth screen is not used with the Service mode, as bandwidth settings are based on services.

Queue shaping can be based per queue and/or per interface. Shaping is determined by the lower specified value.The queue shaping type is selected in the Bandwidth screen.

Interface  The interface for which the queue shaping information is displayed. Either select Unit No and select the unit number and port from the drop-down menus, or select LAG and select the LAG number from the drop- down menu.

Enable Ingress Rate Limit Status  Indicates if rate limiting is defined on the interface.

Enable Egress Shaping Rate  Indicates if rate limiting is enabled on the interface.

SLM224G4S specifications

The Linksys SLM224G4S is a sophisticated Layer 2 managed switch designed for businesses and institutions that demand high performance, reliability, and advanced networking features. This model stands out due to its blend of robustness and manageability, making it ideal for expanding networks.

One of the primary features of the SLM224G4S is its 24 Gigabit Ethernet ports, allowing for high-speed data transfers essential for bandwidth-intensive applications. Supporting auto-negotiation, these ports can detect the capabilities of connected devices and configure themselves accordingly, ensuring optimal performance without manual intervention. With four additional shared Gigabit SFP (Small Form-factor Pluggable) ports, this switch provides flexibility in network design and enhances scalability.

The SLM224G4S supports VLAN (Virtual Local Area Network) capabilities, which can segment network traffic to improve security and performance. This is particularly useful in environments where different departments or teams require distinct network segments for operational efficiency. By implementing VLANs, organizations can enhance their network management while isolating sensitive information from potential threats.

Quality of Service (QoS) is another critical technology integrated into the SLM224G4S. It prioritizes network traffic, ensuring that critical applications receive the bandwidth they need for optimal performance. This is particularly important for VoIP and video conferencing applications, where latency and jitter can significantly impact user experience.

The switch also features advanced Layer 2 management functionalities, including SNMP (Simple Network Management Protocol), allowing IT administrators to monitor network performance and quickly troubleshoot issues. The embedded web-based management interface makes configuration straightforward, enabling quick adjustments to settings without deep networking knowledge.

Security is a paramount consideration in today’s networking landscape. The SLM224G4S provides robust security features, including port security that limits the number of MAC addresses allowed on a port, reducing the risk of unauthorized access. Moreover, it supports802.1X port-based authentication, ensuring that only authenticated devices can connect to the network.

In summary, the Linksys SLM224G4S managed switch boasts features such as 24 Gigabit Ethernet ports, VLAN support, QoS, SNMP management, and advanced security protocols. These characteristics make it an excellent choice for businesses looking to enhance their network's performance, safety, and reliability, paving the way for seamless connectivity in today’s digital age.
