Spanning Tree Algorithm Configuration

The STP Port Information and STP Trunk Information pages display the current status of ports and trunks in the Spanning Tree.

Command Attributes

Note: The following attributes are read-only and cannot be changed:

• Spanning Tree:	Shows if STA has been enabled on this interface.

• STA Status:	Displays current state of this port within the Spanning Tree:
	• Discarding - Port receives STA configuration messages, but does not forward
	packets.
	• Learning - Port has transmitted configuration messages 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.
	The rules defining port status are:
	• A port on a network segment with no other STA compliant bridging device is always
	forwarding.
	• If two ports of a switch are connected to the same segment and there is no other
	STA device attached to this segment, the port with the smaller ID forwards packets
	and the other is discarding.
	• All ports are discarding when the switch is booted, then some of them change state
	to learning, and then to forwarding.

• Forward Transitions:	The number of times this port has changed from the Learning state to the Forward-
	ing state.

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

• Designated Bridge:	The bridge priority and MAC address of the device through which this port must com-
	municate to reach the root of the Spanning Tree.

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

• Oper Link Type:	The operational point-to-point status of the LAN segment attached to this interface.
	This parameter is determined by manual configuration or by auto-detection, as
	described for Admin Link Type in STA Port Configuration on page 120.

• Oper Edge Port:	This parameter is initialized to the setting for Admin Edge Port in STA Port Configu-
	ration on page 120 (i.e., true or false), but will be set to false if a BPDU is received,
	indicating that another bridge is attached to this port.

• Port Role:	Roles are assigned according to whether the port is part of the active topology con-
	necting 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 an alternate or backup port that
	may provide connectivity if other bridges, bridge ports, or LANs fail or are removed.

118	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.
