SPANNING TREE ALGORITHM CONFIGURATION

•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.

•Designated Root – The priority and MAC address of the device in the Spanning Tree that this switch has accepted as the root device.

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

-Root Path Cost – The path cost from the root port on this switch to the root device.

•Configuration Changes – The number of times the Spanning Tree has been reconfigured.

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

These additional parameters are only displayed for the CLI:

•Spanning tree mode – Specifies the type of spanning tree used on this switch:

-STP: Spanning Tree Protocol (IEEE 802.1D)

-RSTP: Rapid Spanning Tree (IEEE 802.1w)

-MSTP: Multiple Spanning Tree (IEEE 802.1s)

•Spanning tree backup root – Automatically lowers the switch’s bridge priority by 4096 if it loses contact with the current root device. To succeed, the switch must have a direct connection to current root bridge, and its adjusted bridge priority must be higher (i.e., a numerically lower value) than all the other bridges in the spanning tree.

•Instance – Instance identifier of this spanning tree. (This is always 0 for the CIST.)

•VLANs configuration – VLANs assigned to the CIST.

SMC6824M specifications

The SMC Networks SMC6824M is a robust and reliable managed switch that caters to the needs of small to mid-sized businesses, as well as enterprise environments. This switch is designed to provide enhanced performance, scalability, and security for network infrastructures that require efficient traffic management and comprehensive control.

One of the key features of the SMC6824M is its 24 10/100/1000BASE-T ports, which offer lightning-fast Ethernet connectivity. These ports are capable of auto-negotiation, allowing devices to automatically adjust their settings for optimal performance, making it easier to integrate various hardware into existing networks. Additionally, the switch includes four Gigabit SFP slots for fiber uplinks, which allow for extended connectivity options and improved network design.

The SMC6824M employs advanced Layer 2 and Layer 3 functionalities, giving network administrators the tools they need to manage their networks effectively. It supports features like VLAN (Virtual Local Area Network) support and Quality of Service (QoS), ensuring efficient bandwidth management and enhanced performance for critical applications. Through VLAN segmentation, it can isolate network traffic for different departments or functions, enhancing security and reducing congestion.

The switch also offers comprehensive network management capabilities through SNMP (Simple Network Management Protocol) and a web-based interface, enabling easy configuration, monitoring, and troubleshooting. The SMC6824M includes support for port mirroring, which is important for diagnostics and monitoring network performance.

Another significant characteristic of the SMC6824M is its redundancy features, which include IEEE 802.1d Spanning Tree Protocol (STP) to prevent loops and provide network resilience. This is essential for maintaining continuous operation, especially in dynamic environments where network availability is critical.

In terms of security, the SMC6824M supports 802.1X port-based authentication, ensuring that only authorized devices gain access to the network. This feature is crucial for protecting sensitive data and maintaining the integrity of the network.

Overall, the SMC Networks SMC6824M is a versatile and feature-rich managed switch that delivers the performance and flexibility required to support growing networks. Its combination of layer management, security features, and user-friendly interface makes it an excellent choice for organizations looking to enhance their network infrastructure.
