Configuring the Switch

Port Management

Port functionality can be controlled using the Port Management settings.. Speeds, duplex, grouping, and Power over Ethernet settings, and more can be defined..

Port Management > Port Settings

You can manually configure the speed, duplex mode, and flow control used on specific ports, or use to detect the connection settings used by the attached device.. Use the full-duplex mode on ports whenever possible to double the throughput of switch connections.. Flow control should also be enabled to control network traffic during periods of congestion and prevent the loss of packets when port buffer thresholds are exceeded.. The Switch supports flow control based on the IEEE 802..3x standard..

This screen displays the current connection status, including the description, administrative status, link status, speed, duplex mode, MDI/MDIX, flow control, type, and LAG..

Port Management > Port Settings

Port  Displays the port number..

Description  Displays a description for the port, if one has been defined..

Administrative Status  Displays the administrative status of the appropriate port..

Link Status  Displays the link status of the port.. Speed  Displays the current speed of the port.. Duplex  Displays the current duplex mode of the port..

MDI/MDIX  Indicates if the port is being utilized as an MDI or MDIX port..

Flow Control  Indicates the type of flow control currently in use (IEEE 802..3x, Back-Pressure, or None)..

Type  Indicates the port type ((100Base-TX, 1000Base-T, or SFP)..

LAG  Indicates whether the port is a LAG member..

Each port has a Detail button that opens a screen for editing port settings.. Click the Detail button to open the Port Setting detail screen for the desired port..

Edit Port Settings

You can use the Port Setting detail screen to enable/disable an interface, set and interface capability advertisements, or manually force the speed, duplex mode, and flow control..

Port Management > Edit Port Settings

This screen allows you to edit the following information for each port on the Switch..

Port  Use the port drop-down menu to select a port..

Port Configuration

Description  Use this field to describe the interface.. (Range: 1-64 characters)

Speed Duplex  Used to manually set the port speed and duplex mode when autonegotiation is disabled..

Autonegotiation  Enables or disables autonegotiation.. When autonegotiation is enabled, you need to specify the capabilities to be advertised.. When autonegotiation is disabled, you can force the settings for speed, mode, and flow control.. Autonegotiation is enabled by default..

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.
