Configuring the Switch

Spanning Tree > STP Status

Spanning Tree > STP Status

You can display a summary of the current bridge STA information that applies to the entire Switch using the information screen.. This screen displays the following information..

Spanning Tree State  Shows if the Switch is enabled to participate in an STA-compliant network..

Spanning Tree Mode  Shows the type of protocol that the Switch is using..

Bridge ID  A unique identifier for this bridge, consisting of the bridge priority and MAC address (where the address is taken from the Switch system)..

Designated Root  The priority and MAC address of the device in the Spanning Tree that the Switch has accepted as the root device..

Root Port  The number of the port on the Switch that is closest to the root.. The Switch communicates with the root device through this port.. If there is no root port, then the Switch has been accepted as the root device of the Spanning Tree network..

Root Path Cost  The path cost from the root port on the Switch to the root device..

Root Maximum Age  The maximum time (in seconds) a device can wait without receiving a configuration message before attempting to reconfigure.. All device ports (except for designated ports) should receive configuration messages at regular intervals.. Any port that ages out STA information (provided in the last configuration message) becomes the designated port for the attached LAN.. If it is a root port, a new root port is selected from among the device ports attached to the network.. (References to “ports” in this section mean “interfaces,” which includes both ports and LAGs..)

Root Hello Time  Interval (in seconds) at which the Switch transmits a configuration message..

Root Forward Delay  The maximum time (in seconds) the root device will wait before changing states (i..e.., discarding to learning to forwarding).. This delay is required because every device must receive information about topology changes before it starts to forward frames.. In addition, each port needs time to listen for conflicting information that would make it return to a discarding state; otherwise, temporary data loops might result..

Topology Changes Counts  The number of times the Spanning Tree has been reconfigured..

Last Topology Change  Time since the Spanning Tree was last reconfigured..

Spanning Tree > Global STP

Spanning Tree > Global STP

Configure the global settings for STP using this screen.. Global settings apply to the entire Switch..

Spanning Tree State  Enables/disables STP on the Switch.. Use the checkbox to enable or disable STP on the Switch.. (Default: Enabled)..

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.
