Spanning Tree Algorithm Configuration

Field Attributes

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

•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).

•Max 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.

Note: References to “ports” in this section mean “interfaces,” which includes both ports and trunks.

•Hello Time: Interval (in seconds) at which the root device transmits a configuration message.

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

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

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)

•Priority:Bridge priority is used in selecting the root device, root port, and designated port. The device with the highest priority becomes the STA root device. However, if all devices have the same priority, the device with the lowest MAC address will then become the root device.

•Root Hello Time: Interval (in seconds) at which this device transmits a configuration message.

•Root Maximum Age: The maximum time (in seconds) this device can wait without receiving a configura- tion message before attempting to reconfigure.

All device ports (except for designated ports) should receive configuration messages at regular intervals.

If the root port ages out STA information (provided in the last configuration mes- sage), a new root port is selected from among the device ports attached to the net- work.

114	NXA-ENET24 - Software Management Guide

NXA-ENET24 specifications

The AMX NXA-ENET24 is a versatile and powerful networked control interface designed to meet the growing demands of modern AV systems. This network switch offers an exceptional combination of reliability, performance, and scalability, making it an ideal choice for professional environments such as conference rooms, educational facilities, and control rooms.

One of the key features of the NXA-ENET24 is its 24-port configuration, allowing for extensive connectivity options. Each port supports 10/100/1000 Mbps speeds, ensuring that high bandwidth applications are handled with ease. Additionally, the switch incorporates advanced auto-negotiation technology, which automatically configures the optimal speed and duplex mode for connected devices. This ensures seamless connectivity and minimizes the risk of network disruptions.

The NXA-ENET24 is designed with advanced management capabilities, including support for VLANs, which helps to segment network traffic for enhanced security and performance. Network administrators can easily create virtual local area networks to optimize traffic flow and reduce congestion. This feature is particularly beneficial in environments where multiple AV systems operate concurrently.

Another significant characteristic of the NXA-ENET24 is its support for Power over Ethernet, or PoE. This feature enables the switch to deliver electrical power alongside data through the network cables. As a result, devices such as IP cameras, VoIP phones, and wireless access points can be powered directly from the switch, simplifying deployment and reducing the need for additional power sources.

Monitoring and management of the switch are made easier through a user-friendly interface. The NXA-ENET24 supports SNMP for network management, allowing users to monitor performance metrics, configure settings, and receive alerts in case of issues. This level of oversight is crucial for maintaining the stability of AV systems in mission-critical applications.

Durability is another hallmark of the NXA-ENET24 design. The switch features a robust chassis that is engineered to withstand the rigors of professional use. With cooling mechanisms in place and a fanless design, the NXA-ENET24 operates quietly and efficiently, making it suitable for environments where noise is a concern.

In conclusion, the AMX NXA-ENET24 is a powerful, reliable, and feature-rich network switch that effectively supports modern AV applications. With its extensive connectivity options, advanced management capabilities, PoE support, and durable design, it is an excellent choice for integrators and organizations looking to optimize their network infrastructure.
