Configuring the Switch

•Exceed Action  Specifies whether the traffic that exceeds the specified rate or burst will be dropped or the DSCP service level will be reduced..

•Set  DecreasesDSCPpriorityforoutofconformance traffic.. (Range: 0-63)..

•Drop  Drops non-conforming traffic..

Add  Adds the specified criteria to the policy map.. Remove  Deletes a class from a policy..

Add classes to a selected policy and set the Action, Meter, Rate, Burst and Exceed values using the drop-down menus and fields provided then click Add..

QoS > DiffServ Port Binding

QoS > DiffServ Port Binding

This function binds a policy map to the ingress queue of a particular interface.. You must first define a class map, set an ACL mask to match the criteria defined in the class map, then define a policy map, and finally bind the service policy to the required interface.. You can only bind one policy map to an interface.. The current firmware does not allow you to bind a policy map to an egress queue..

Check the checkbox and choose a Policy Map for a port from the drop-down menu..

Click Save Settings to save the changes..

QoS > Bandwidth

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..

QoS > Bandwidth

Port  Displays the port or LAG number..

Status  Enables the rate limit (input or output) for the port or LAG.. (Default: Disabled)

Rate Limit (Kbits/sec)  Sets the rate limit level for the port or LAG.. For Fast Ethernet ports the default is 100000 Kbits/sec (Range: 64-100000).. For Gigabit Ethernet ports the default is 1000000 Kbits/sec (Range: 64-1000000)..

LAG  Indicates if ports are members of a LAG.. To configure a rate limit 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..

Set the Input Rate Limit Status or Output Rate Limit Status, then set the rate limit for individual interfaces or LAGs, then click Save Settings..

Spanning Tree

The Spanning Tree Algorithm (STA) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers.. This allows the Switch to interact with other bridging devices (that is, an STA-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down..

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.
