CLI (Command Line Interface)

Spanning Tree Commands

This section includes commands that configure the Spanning Tree Algorithm (STA) globally for the switch, and commands that configure STA for the selected interface.

Spanning Tree Commands

Command

Function

 

 

spanning-tree

Syntax:

This command enables the

[no] spanning-tree

Spanning Tree Algorithm

Default Setting: Spanning tree is enabled.

globally for the switch.

Command Mode: Global Configuration

Use the no form to disable it.

Command Usage: The Spanning Tree Algorithm (STA) can be used to

 

detect and disable network loops, and to provide backup links between

 

switches, bridges or routers. This allows the switch to interact with other

 

bridging devices (that is, an STA-compliant switch, bridge or router) in your

 

network to ensure that only one route exists between any two stations on

 

the network, and provide backup links which automatically take over when a

 

primary link goes down.

 

Example: This example shows how to enable the Spanning Tree Algorithm

 

for the switch:

 

Console(config)#spanning-tree

 

Console(config)#

 

 

spanning-tree mode

Syntax:

This command selects the

spanning-tree mode {stp rstp}

spanning tree mode for this

no spanning-tree mode

• stp - Spanning Tree Protocol (IEEE 802.1D)

switch.

• rstp - Rapid Spanning Tree Protocol (IEEE 802.1w)

Use the no form to restore the

Default Setting: rstp

default.

 

Command Mode: Global Configuration

 

Command Usage:

 

• Spanning Tree Protocol: Uses RSTP for the internal state machine, but

 

sends only 802.1D BPDUs.

 

• Rapid Spanning Tree Protocol: RSTP supports connections to either STP

 

or RSTP nodes by monitoring the incoming protocol messages and

 

dynamically adjusting the type of protocol messages the RSTP node

 

transmits, as described below:

 

STP Mode – If the switch receives an 802.1D BPDU after a port’s

 

migration delay timer expires, the switch assumes it is connected to an

 

802.1D bridge and starts using only 802.1D BPDUs.

 

RSTP Mode – If RSTP is using 802.1D BPDUs on a port and receives an

 

RSTP BPDU after the migration delay expires, RSTP restarts the

 

migration delay timer and begins using RSTP BPDUs on that port.

 

Example: The following example configures the switch to use Rapid

 

Spanning Tree:

 

Console(config)#spanning-tree mode rstp

 

Console(config)#

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.
