QoS

Network traffic is usually unpredictable, and the only basic assurance that can be offered is best effort traffic delivery. To overcome this challenge, Quality of Service (QoS) is applied throughout the network. This ensures that network traffic is prioritized according to specified criteria, and that specific traffic receives preferential treatment. QoS in the network optimizes network performance and entails two basic facilities:

Classifying incoming traffic into handling classes, based on an attribute, including:

•The ingress interface

•Packet content

•A combination of these attributes

Providing various mechanisms for determining the allocation of network resources to different handling classes, including:

•The assignment of network traffic to a particular hardware queue

•The assignment of internal resources

•Traffic shaping

The terms Class of Service (CoS) and QoS are used in the following context:

•CoS provides varying Layer 2 traffic services. CoS refers to classifying traffic into traffic classes, where each class is handled as an aggregate whole, with no per-flow settings. CoS is usually related to the 802.1p service that classifies flows according to their Layer 2 priority, as set in the VLAN header.

•QoS refers to Layer 2 traffic and above. QoS handles per-flow settings, even within a single traffic class.

The QoS configuration options are CoS Settings, Queue Settings, DSCP Settings, and Basic Mode.

QoS > CoS Settings

The CoS Settings screen is used to enable or disable CoS.

QoS > CoS Settings

CoS Settings

QoS Mode  Indicates if QoS is enabled. The possible values are:

•Disable  Disables QoS.

•Basic  Enables QoS. This is the default value.

Class of Service  Specifies the CoS priority tag values, where 0 is the lowest and 7 is the highest.

Queue  Defines the traffic forwarding queue to which the CoS priority is mapped. Four traffic priority queues are supported.

Click Restore Defaults to restore the device factory defaults for mapping CoS values to a forwarding queue.

CoS Default

Unit No.  The unit to which the CoS configuration applies.

Default CoS  Determines the default CoS value for incoming packets for which a VLAN tag is not defined. The possible field values are 0-7. The default CoS is 0.

LAG  The LAG to which the port belongs, if relevant. If the port is a member of a LAG, the LAG settings override the port settings.

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.
