spanning-tree priority

Syntax:

This command configures the

spanning-tree priority priority

spanning tree priority globally for

no spanning-tree priority

• priority - Priority of the bridge.

Range – 0-61440, in steps of 4096;

Use the no form to restore the

Options: 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768,

default.

36864, 40960, 45056, 49152, 53248, 57344, 61440

 

 

Default Setting: 32768

 

Command Mode: Global Configuration

 

Command Usage: 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.

 

Example:

 

Console(config)#spanning-tree priority 40960

 

Console(config)#

 

 

spanning-tree pathcost

Syntax:

method

spanning-tree pathcost method {long short}

This command configures the

no spanning-tree pathcost method

• long - Specifies 32-bit based values that range from 0-200,000,000.

path cost method used for Rapid

Spanning Tree.

• short - Specifies 16-bit based values that range from 0-65535.

Use the no form to restore the

Default Setting: Long method

default.

Command Mode: Global Configuration

 

Command Usage: The path cost method is used 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. Note that path cost (see spanning-tree cost on page 251) takes pre-

 

cedence over port priority (see spanning-treeport-priorityon page 251).

 

Example:

 

Console(config)#spanning-tree pathcost method long

 

Console(config)#

 

 

spanning-tree transmission-

Syntax:

limit

spanning-tree transmission-limit count

This command configures the

no spanning-tree transmission-limit

• count - The transmission limit in seconds. (Range: 1-10)

Example:

 

Console(config)#spanning-tree transmission-limit 4

 

Console(config)#

 

 

spanning-tree spanning-

Syntax:

disabled

[no] spanning-tree spanning-disabled

This command disables the

Default Setting: Enabled

Spanning Tree Algorithm for the

Command Mode: Interface Configuration (Ethernet, Port Channel)

specified interface.

Example: This example disables the Spanning Tree Algorithm for port 5:

Use the no form to re-enable the

Console(config)#interface ethernet 1/5

Console(config-if)#spanning-tree spanning-disabled

specified interface.

Console(config-if)#

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.
