Port Configuration

Port Statistics (Cont.)

Interface Statistics (Cont.)

Transmit Octets: The total number of octets transmitted out of the interface, including framing characters.

• Transmit Unicast

The total number of packets that higher-level protocols requested be transmitted

Packets:

to a subnetwork-unicast address, including those that were discarded or not

 

sent.

 

 

• Transmit Multicast

The total number of packets that higher-level protocols requested be transmit-

Packets:

ted, and which were addressed to a multicast address at this sub-layer, including

 

those that were discarded or not sent.

Transmit Broadcast The total number of packets that higher-level protocols requested be transmit-

Packets:

ted, and which were addressed to a broadcast address at this sub-layer, includ-

 

ing those that were discarded or not sent.

Transmit Discarded The number of outbound packets which were chosen to be discarded even

Packets:

though no errors had been detected to prevent their being transmitted. One pos-

 

sible reason for discarding such a packet could be to free up buffer space.

Transmit Errors: The number of outbound packets that could not be transmitted because of errors.

Etherlike Statistics

Alignment Errors: The number of alignment errors (missynchronized data packets).

Late Collisions: The number of times that a collision is detected later than 512 bit-times into the transmission of a packet.

FCS Errors:A count of frames received on a particular interface that are an integral number of octets in length but do not pass the FCS check. This count does not include frames received with frame-too-long or frame-too-short error.

Excessive Collisions: A count of frames for which transmission on a particular interface fails due to excessive collisions. This counter does not increment when the interface is oper- ating in full-duplex mode.

• Single Collision

The number of successfully transmitted frames for which transmission is inhib-

Frames:

ited by exactly one collision.

 

 

• Internal MAC

A count of frames for which transmission on a particular interface fails due to an

Transmit Errors:

internal MAC sublayer transmit error.

 

 

• Multiple Collision

A count of successfully transmitted frames for which transmission is inhibited by

Frames:

more than one collision.

Carrier Sense Errors: The number of times that the carrier sense condition was lost or never asserted when attempting to transmit a frame.

SQE Test Errors: A count of times that the SQE TEST ERROR message is generated by the PLS sublayer for a particular interface.

Frames Too Long: A count of frames received on a particular interface that exceed the maximum permitted frame size.

Deferred Transmissions: A count of frames for which the first transmission attempt on a particular inter- face is delayed because the medium was busy.

• Internal MAC

A count of frames for which reception on a particular interface fails due to an

Receive Errors:

internal MAC sublayer receive error.

 

 

RMON Statistics

 

Drop Events:The total number of events in which packets were dropped due to lack of resources.

• Jabbers:

The total number of frames received that were longer than 1518 octets (exclud-

 

ing framing bits, but including FCS octets), and had either an FCS or alignment

 

error.

Received Bytes: Total number of bytes of data received on the network. This statistic can be used as a reasonable indication of Ethernet utilization.

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.
