Configuring the Switch

Port to CoS

Modify the default priority for any interface using the text field provided..

Port  Displays the port number..

Default CoS (0-7) The priority that is assigned to untagged frames received on the interface.. (Range: 0-7, where 7 is the highest priority)

LAG  Indicates if ports are members of a LAG.. To configure the default priority for LAGs, go to the table entry for the LAG number, which is listed after ports Gig 1 and Gig 2 at the end of the table..

Default settings can be restored using the Restore Defaults button..

Click Save Settings to save the changes..

The Switch prioritizes each packet based on the required level of service, using four priority queues with strict or Weighted Round Robin Queuing.. It uses IEEE 802..1p and 802..1Q tags to prioritize incoming traffic based on input from the end-station application.. These functions can be used to provide independent priorities for delay-sensitive data and best-effort data..

Queue Settings

You can set the Switch to service the queues based on a strict rule that requires all traffic in a higher priority queue to be processed before lower priority queues are serviced, or use Weighted Round-Robin (WRR) queuing that specifies a relative weight of each queue.. WRR uses a predefined relative weight for each queue that determines the percentage of service time the Switch services each queue before moving on to the next queue.. This prevents the head-of-line blocking that can occur with strict priority queuing..

•StrictPriority  Servicestheegressqueuesinsequential order, transmitting all traffic in the higher priority queues before servicing lower priority queues..

•WRR  Weighted Round-Robin shares bandwidth at the egress ports by using scheduling weights 1, 2, 4, 8 for queues 0 through 3 respectively..

Set the Queue Mode to Strict or WRR using the Queue Mode drop-down menu then click Save Settings

Queue Scheduling

The Switch uses the Weighted Round Robin (WRR) algorithm to determine the frequency at which it services each priority queue.. A weight is assigned to each of these queues (and thereby to the corresponding traffic priorities).. This weight sets the frequency at which each queue will be polled for service, and subsequently affects the response time for software applications assigned a specific priority value..

The queue weighting is fixed for the Switch and cannot be configured..

SRW248G4P specifications

Cisco Systems SRW248G4P is a high-performance Layer 2 switch designed specifically for small to medium-sized businesses that require robust networking solutions. This switch supports Power over Ethernet (PoE), providing a highly flexible option for powering devices such as IP phones, wireless access points, and surveillance cameras.

One of the standout features of the SRW248G4P is its 48 10/100 Ethernet ports, which ensure ample connectivity for various networked devices. Additionally, it offers four Gigabit Ethernet uplink ports, allowing for seamless integration with existing network infrastructure and facilitating high-speed data transfer. The combination of these ports enables businesses to expand their network capabilities as needed without the immediate requirement for added devices.

The SRW248G4P comes equipped with advanced Layer 2 switching capabilities, including VLAN support, which enables the segmentation of network traffic for improved performance and security. It also supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), which help prevent network loops and ensure redundancy. With features like Link Aggregation Control Protocol (LACP), multiple physical connections can be combined into a single logical link, enhancing bandwidth and providing failover capabilities.

Another critical attribute of the Cisco SRW248G4P is its user-friendly management interface. The switch can be managed through a web-based interface, allowing IT administrators to configure settings, monitor performance, and troubleshoot issues with ease. Additionally, it supports SNMP (Simple Network Management Protocol) for integration with network management systems, further simplifying monitoring tasks.

Power over Ethernet functionality is a significant advantage of the SRW248G4P, providing up to 15.4 watts per port. This capability simplifies installation and reduces the clutter of power cords and outlets. Organizations can deploy PoE-enabled devices in locations that lack power sources, thus enhancing overall flexibility in network design.

In summary, the Cisco Systems SRW248G4P is a feature-rich switch tailored for small to medium-sized enterprises. Its blend of performance, management capabilities, and advanced features like PoE makes it a valuable asset in any organization's networking setup. By ensuring reliable connectivity and ease of management, businesses can focus more on growth and their core objectives rather than worrying about network complexities.
