Syntax:

This command shows the CoS

show map access-list ip [interface]

value mapped to an IP ACL for

matching an ACL rule.

Command Mode: Privileged Exec

 

 

Example:

 

Console#show map access-list ip

match access-list ip

Syntax:

This command changes the IEEE

match access-list ip acl_name [set priority priority] {set tos

802.1p priority, IP Precedence, or

tos_value set dscp dscp_value}

no match access-list ip acl_name

DSCP Priority of a frame match-

• acl_name – Name of the ACL. (Maximum length: 16 characters)

ing the defined ACL rule.

• priority – Class of Service value in the IEEE 802.1p priority tag. (Range:

This feature is commonly referred

to as ACL packet marking.

0-7; 7 is the highest priority)

• tos_value – IP Precedence value. (Range: 0-7)

Use the no form to remove the

• dscp_value – Differentiated Services Code Point value.

ACL marker.

(Range: 0-63)

 

 

Default Setting: None

 

Command Mode: Interface Configuration (Ethernet)

 

Command Usage: You must configure an ACL mask before you can

 

change frame priorities based on an ACL rule.

 

Traffic priorities may be included in the IEEE 802.1p priority tag. This tag is

 

also incorporated as part of the overall IEEE 802.1Q VLAN tag. To specify

 

this priority, use the set priority keywords.

 

The IP frame header also includes priority bits in the Type of Service (ToS)

 

octet. The Type of Service octet may contain three bits for IP Precedence

 

or six bits for Differentiated Services Code Point (DSCP) service. To spec-

 

ify the IP precedence priority, use the set tos keywords. To specify the

 

DSCP priority, use the set dscp keywords. Note that the IP frame header

 

can include either the IP Precedence or DSCP priority type.

 

The precedence for priority mapping by this switch is IP Precedence or

 

DSCP Priority, and then 802.1p priority.

 

Example:

 

Console(config)#interface ethernet 1/12

 

Console(config-if)#match access-list ip bill set dscp 0

 

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.
