map ip dscp

Syntax:

(Interface Configuration)

map ip dscp dscp-value cos cos-value

This command sets IP

no map ip dscp

dscp-value - 8-bit DSCP value. (Range: 0-63)

DSCP priority (i.e.,

cos-value - Class-of-Service value (Range: 0-7)

Differentiated Services

Code Point priority).

Default Setting: The DSCP default values are defined in the following table. Note

Use the no form to restore

that all the DSCP values that are not specified are mapped to CoS value 0

the default table.

IP DSCP to CoS Values

 

Command Mode: Interface Configuration (Ethernet, Port Channel)

 

Command Usage: The precedence for priority mapping is IP Port, IP Prece-

 

dence or IP DSCP, and default switchport priority.

 

DSCP priority values are mapped to default Class of Service values according to

 

recommendations in the IEEE 802.1p standard, and then subsequently mapped

 

to the four hardware priority queues.

 

This command sets the IP DSCP priority for all interfaces.

 

Example: The following example shows how to map IP DSCP value 1 to CoS

 

value 0:

 

 

Console(config)#interface ethernet 1/5

 

Console(config-if)#map ip dscp 1 cos 0

 

Console(config-if)#

 

 

 

show map ip port

Syntax:

 

Use this command to show

show map ip port [interface]

the IP port priority map.

ethernet unit/port

 

unit - Stack unit. (Range: 1-8)

 

port - Port number. (Range: 1-26)

Default Setting: None

 

Command Mode: Privileged Exec

 

Example: The following shows that HTTP traffic has been mapped to CoS value

 

0:

 

 

Console#show map ip port

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.
