24-Port 10/100/1000 Gigabit Switch with Webview and PoE

QoS Tab - DSCP Settings

The Switch supports a common method of prioritizing layer 3/4 traffic to meet application requirements. Traffic priorities can be specified in the IP header of a frame using the priority bits in the Type of Service (ToS) octet. If priority bits are used, the ToS octet may contain six bits for Differentiated Services Code Point (DSCP) service.

When these services are enabled, the priorities are mapped to a Class of Service value by the Switch and the traffic then sent to the corresponding output queue. Because different priority information may be contained in the traffic, the Switch maps priority values to the output queues in the following manner:

The precedence for priority mapping is DSCP Priority and then Default Port Priority.

To enable DSCP priority mapping, select DSCP Priority Status.

Priority Status. Enables the DSCP priority mapping. (Enabled is the default setting.)

DSCP to CoS. Maps Differentiated Services Code Point values to CoS values.

QoS Tab - Diffserv Settings

The commands described in this section are used to configure Quality of Service (QoS) classification criteria and service policies. Differentiated Services (DiffServ) provides policy-based management mechanisms used for prioritizing network resources to meet the requirements of specific traffic types on a per hop basis. Each packet is classified upon entry into the network based on access lists, IP Precedence, DSCP values, or VLAN lists. Using access lists allows you select traffic based on Layer 2, Layer 3, or Layer 4 information contained in each packet. Based on configured network policies, different kinds of traffic can be marked for different kinds of forwarding.

All switches or routers that access the Internet rely on class information to provide the same forwarding treatment to packets in the same class. Class information can be assigned by end hosts, or switches or routers along the path. Priority can then be assigned based on a general policy, or a detailed examination of the packet. However, note that detailed examination of packets should take place close to the network edge so that core switches and routers are not overloaded.Switches and routers along the path can use class information to prioritize the resources allocated to different traffic classes. The manner in which an individual device handles traffic in the DiffServ architecture is called per-hop behavior. All devices along a path should be configured in a consistent manner to construct a consistent end-to-end QoS solution.

SRW2024P specifications

The Linksys SRW2024P is a robust and versatile managed switch designed to meet the networking needs of small to medium-sized businesses. This switch features 24 Ethernet ports, making it suitable for connecting multiple devices while delivering exceptional performance and reliability. One of the standout features of the SRW2024P is its Power over Ethernet (PoE) capability, allowing users to power devices like IP cameras, VoIP phones, and wireless access points directly from the switch, eliminating the need for additional power sources and simplifying installations.

The SRW2024P supports a range of advanced technologies, including VLANs (Virtual Local Area Networks), which enable network segmentation and improved security by isolating different network segments. This segmentation can help enhance performance and control broadcast domains effectively. Additionally, the switch supports Quality of Service (QoS), allowing users to prioritize network traffic, ensuring that critical applications receive the necessary bandwidth for optimal performance. This feature is particularly beneficial in environments with high-definition video streaming or VoIP communications.

Another critical aspect of the Linksys SRW2024P is its support for robust network security protocols. With features like 802.1X port-based authentication, network administrators can enforce strict access control policies, ensuring that only authorized devices can connect to the network. The switch also provides basic security features such as MAC address filtering and access control lists (ACLs), enhancing the overall security of the network.

The easy-to-use web-based management interface makes it simple for administrators to configure and monitor the switch. It provides real-time information about network performance, port status, and traffic statistics, allowing for effective troubleshooting and management. The SRW2024P also includes the capability for SNMP (Simple Network Management Protocol), enabling integration with third-party network management solutions for more advanced monitoring and control.

In terms of physical characteristics, the Linksys SRW2024P is designed for reliable performance in various environments, with a compact rack-mountable chassis. This design allows for easy installation in standard 19-inch racks, making it a practical choice for businesses looking to optimize their network infrastructure.

In summary, the Linksys SRW2024P managed switch combines advanced networking features, ease of management, and PoE capabilities, making it an ideal choice for growing businesses looking to enhance their connectivity and network performance. With its reliable security measures, VLAN support, and QoS capabilities, the SRW2024P provides a solid foundation for a robust and scalable network.
