Configuring the Switch

The Port Information displays the current status of the ports in the Spanning Tree..

Port  Displays the port number..

State  Shows if Spanning Tree has been enabled on this interface.. To enable STP on a port click the state checkbox for that port then click Save Settings to save the changes..

Status  Displays current state of this port within the Spanning Tree:

•Discarding  Port receives STA configuration messages, but does not forward packets..

•Learning  Porthastransmittedconfigurationmessages for an interval set by the Forward Delay parameter without receiving contradictory information.. Port address table is cleared, and the port begins learning addresses..

•Forwarding  Port forwards packets, and continues learning addresses..

Role  Roles are assigned according to whether the port is part of the active topology connecting the bridge to the root bridge (i..e.., root port), connecting a LAN through the bridge to the root bridge (i..e.., designated port), or is the MSTI regional root (i..e.., master port); or is an alternate or backup port that may provide connectivity if other bridges, bridge ports, or LANs fail or are removed.. The role is set to disabled (i..e.., disabled port) if a port has no role within the spanning tree..

Forward Transitions  The number of times this port has transitioned from the Learning state to the Forwarding state..

Operational Edge Port  This parameter is initialized to the setting for Administrative Edge Port in STP Port Setting detail, but will be set to false if a BPDU is received indicating that another bridge is attached to this port..

Click on Detail to configure STP Port Settings for an interface..

Click Detail to configure Path Cost, Priority, Administrative Edge Port (Fast Forwarding), and Administrative Link Type.. Use the text fields provided to edit the values, then click Apply..

Spanning Tree > STP Port Settings > STP Port Setting Detail

Designated Cost  The cost for a packet to travel from this port to the root in the current SpanningTree configuration.. The slower the media, the higher the cost..

Designated Port  The port priority and number of the port on the designated bridging device through which the Switch must communicate with the root of the Spanning Tree..

Designated Bridge  The bridge priority and MAC address of the device through which this port must communicate to reach the root of the Spanning Tree..

Path Cost  This parameter is used by the STP to determine the best path between devices.. Therefore, lower values should be assigned to ports attached to faster media, and higher values assigned to ports with slower media.. Path cost takes precedence over port priority..

NOTE: When the Path Cost Method is set to “short,” the maximum path cost is 65,535..

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.
