flowcontrol

Syntax:

This command enables flow

[no] flowcontrol

control.

Default Setting: Flow control enabled

Use the no form to disable

Command Mode: Interface Configuration (Ethernet, Port Channel)

flow control.

Command Usage: 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.

 

To force flow control on or off (with the flowcontrol or no flowcontrol command),

 

use the no negotiation command to disable auto-negotiation on the selected

 

interface.

 

When using the negotiation command to enable auto-negotiation, the optimal

 

settings will be determined by the capabilities command. To enable flow control

 

under auto-negotiation, “flowcontrol” must be included in the capabilities list for

 

any port

 

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.

 

Example: The following example enables flow control on port 5:

 

Console(config)#interface ethernet 1/5

 

Console(config-if)#flowcontrol

 

Console(config-if)#no negotiation

 

Console(config-if)#

 

 

shutdown

Syntax:

This command disables an

[no] shutdown

interface.

Default Setting: All interfaces are enabled.

To restart a disabled

Command Mode: Interface Configuration (Ethernet, Port Channel)

interface, use the no form.

Command Usage: This command allows you to disable a port due to abnormal

 

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

 

been resolved. You may also want to disable a port for security reasons.

 

Example: The following example disables port 5:

 

Console(config)#interface ethernet 1/5

 

Console(config-if)#shutdown

 

Console(config-if)#

 

 

switchport broadcast

Syntax:

This command configures

broadcast storm control.

(Range: 64-95232000)

Use the no form to disable

Default Setting: Enabled for all ports

broadcast storm control.

 

Packet-rate limit: 32000 octets per second

 

Command Mode: Interface Configuration (Ethernet)

 

Command Usage: When broadcast traffic exceeds the specified threshold,

 

packets above that threshold are dropped.

 

This command can enable or disable broadcast storm control for the selected

 

interface. However, the specified threshold value applies to all ports on the

 

switch.

 

Example: The following shows how to configure broadcast storm control at 600

 

packets per second:

 

Console(config)#interface ethernet 1/5

 

Console(config-if)#switchport broadcast octet-rate 600

 

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.
