24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet

Rate Limit

This function allows the network manager to control the maximum rate for traffic transmitted or received on an interface. Rate limiting is configured on interfaces at the edge of a network to limit traffic coming out of the switch. Traffic that falls within the rate limit is transmitted, while packets that exceed the acceptable amount of traffic are dropped.

Rate limiting can be applied to individual ports or lags. When an interface is configured with this feature, the traffic rate will be monitored by the hardware to verify conformity. Non-conforming traffic is dropped, conforming traffic is forwarded without any changes.

The rate limit screen displays both Fast Ethernet Granularity and Gigabit Granularity.

Rate limit granularity is an additional feature enabling the network manager greater control over traffic on the network. The “rate limit granularity” is multiplied by the “rate limit level” to set the actual rate limit for an interface. Granularity is a global setting that applies to Fast Ethernet or Gigabit Ethernet interfaces.

Use the drop-down menus to change the rate limit for fast ethernet and/or gigabit granularity, click submit.

Set the Input Rate Limit Status or Output Rate Limit Status, then set the rate limit for the individual interfaces, and click Apply.

To configure input rate limit for each port or lag, click Port Conf or Trunk Conf in the Input row of the table respectively.

To configure output rate limit for each port or lag, click Port Conf or Trunk Conf in the Output row of the table respectively.

Rate Limit Configuration

To configure Port Input Rate Limit, click the Enable checkbox and then set the rate limit level in the textfield provided.

Port Rate Output Limit is configured the same way on the Port Output Rate Limit Configuration screen.

If a port is assigned as a lag member then the rate limit of that port cannot be set in the port configuration screen.

Truck Rate Limit is configured the same way as port rate limit using the trunk Input and output screens.

QoS

Figure 5-31: QoS - Rate Limit

NOTE: When the rate limit granularity is set to a low value (for 10/100 ports, less than 512 Kbps), the maximum bandwidth available on ports is restricted to a value that is "256 x granularity." This restriction also applies to ports with rate limiting disabled.

SRW224P specifications

The Linksys SRW224P is a versatile and efficient managed switch that caters to the needs of small to medium-sized businesses. This Layer 2 switch stands out with its robust functionality and user-friendly design, making it an ideal choice for networking professionals looking to enhance their network infrastructure.

One of the standout features of the SRW224P is its 24 Gigabit Ethernet ports, which provide high-speed connectivity for various devices across the network. This is particularly beneficial in environments with bandwidth-hungry applications, such as data transfers, video conferencing, and online collaboration tools. Additionally, the switch comes with 2 dual-personality ports that can be used as either Gigabit Ethernet or SFP (Small Form-factor Pluggable) ports, allowing for flexible and scalable network setups.

Power over Ethernet (PoE) capability is another significant aspect of the SRW224P. With a total PoE output of up to 370 watts, the switch can power devices such as IP cameras, VoIP phones, and wireless access points directly through the Ethernet cable, simplifying the installation process and reducing cable clutter. This feature is particularly advantageous for organizations seeking to deploy network devices in areas where power outlets are limited.

The SRW224P also boasts advanced management features, including VLAN support for segmenting network traffic, Quality of Service (QoS) for prioritizing critical applications, and Spanning Tree Protocol (STP) for redundant network paths. These capabilities enhance network performance and reliability, ensuring that users experience minimal downtime and efficient data flow.

Security is a top priority with the SRW224P, which includes features such as port security, access control lists (ACLs), and DHCP snooping. These measures help protect the network from unauthorized access and potential attacks, safeguarding sensitive information and maintaining operational integrity.

In terms of user interface, the Linksys SRW224P is equipped with a web-based management interface that allows for easy configuration and monitoring. This intuitive interface enables IT administrators to manage the switch remotely, providing real-time insights into network performance and facilitating troubleshooting.

Overall, the Linksys SRW224P managed switch combines high performance, advanced features, and security measures that make it a reliable choice for businesses aiming to optimize their network infrastructure. Its PoE capabilities, extensive port options, and management features ensure that it meets the demands of modern networking environments, making it a valuable asset for any organization.
