Port Configuration

Configuring Interface Connections

You can use the Port Configuration or Trunk Configuration page to enable/disable an interface, set auto- negotiation and the interface capabilities to advertise, or manually fix the speed, duplex mode, and flow control.

Command Attributes

Command Attributes

• Name

Allows you to label an interface. (Range: 1-64 characters)

 

 

• Admin

Allows you to manually disable an interface. You can disable an interface due to abnor-

 

mal behavior (e.g., excessive collisions), and then re-enable it after the problem has

 

been resolved. You may also disable an interface for security reasons.

•Speed/Duplex Allows manual selection of port speed and duplex mode (i.e., with auto-negotiation dis- abled).

•Flow Control Allows automatic or manual selection of flow control.

•Autonegotiation Allows auto-negotiation to be enabled/disabled. When auto-negotiation is enabled, you (Port Capabilities) need to specify the capabilities to be advertised. When auto-negotiation is disabled,

you can force the settings for speed, mode, and flow control.The following capabilities are supported.

 

• 10half - Supports 10 Mbps half-duplex operation

 

• 10full - Supports 10 Mbps full-duplex operation

 

• 100half - Supports 100 Mbps half-duplex operation

 

• 100full - Supports 100 Mbps full-duplex operation

 

• 1000full - Supports 1000 Mbps full-duplex operation

 

• Sym (Gigabit only) - When specified, the port transmits and receives pause frames;

 

when not specified, the port will auto-negotiate to determine the sender and receiver

 

for asymmetric pause frames. (The current switch chip only supports symmetric

 

pause frames.)

 

• FC - Supports flow control

 

Flow control can eliminate frame loss by “blocking” traffic from end stations or

 

segments connected directly to the switch when its buffers fill. When enabled, back

 

pressure is used for half-duplex operation and IEEE 802.3x for full-duplex operation.

 

(Avoid using flow control on a port connected to a hub unless it is actually required to

 

solve a problem. Otherwise back pressure jamming signals may degrade overall

 

performance for the segment attached to the hub.)

 

• Default: Autonegotiation enabled;

 

Advertised capabilities for

 

• 100BASE-TX – 10half, 10full, 100half, 100full;

 

• 1000BASE-T – 10half, 10full, 100half, 100full, 1000full;

 

• 1000BASE-LX – 1000full)

 

 

• Trunk

Indicates if a port is a member of a trunk.

 

To create trunks and select port members, see Creating Trunk Groups section on

 

page 88.

Autonegotiation must be disabled before you can configure or force the interface to use the Speed/Duplex Mode or Flow Control options.

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.
