VLAN Configuration

Private VLANs

Private VLANs provide port-based security and isolation between ports within the assigned VLAN. This switch supports two types of private VLAN ports: promiscuous, and community ports. A promiscuous port can communicate with all interfaces within a private VLAN. Community ports can only communicate with other ports in their own community VLAN, and with their designated promiscuous ports. (Note that private VLANs and normal VLANs can exist simultaneously within the same switch.)

Each private VLAN consists of two components: a primary VLAN and one or more community VLANs. A primary VLAN allows traffic to pass between promiscuous ports, and between promiscuous ports and community ports subordinate to the primary VLAN. A community VLAN conveys traffic between community ports, and from the community ports to their associated promiscuous ports. Multiple primary VLANs can be configured on this switch, and multiple community VLANs can be configured within each primary VLAN.

To configure private VLANs, follow these steps:

1.Use the Private VLAN Configuration menu (page 133) to designate one or more community VLANs and the primary VLAN that will channel traffic outside of the community groups.

2.Use the Private VLAN Association menu (page 133) to map the secondary (i.e., community) VLAN(s) to the primary VLAN.

3.Use the Private VLAN Port Configuration menu (page 135) to set the port type to promiscuous (i.e., having access to all ports in the primary VLAN) or host (i.e., having access restricted to community VLAN members, and channeling all other traffic through a promiscuous port). Then assign any promiscuous ports to a primary VLAN and any host ports a secondary VLAN (i.e., community VLAN).

Displaying Current Private VLANs

The Private VLAN Information page displays information on the private VLANs configured on the switch, including primary and community VLANs, and their associated interfaces.

Command Attributes

•VLAN ID: ID of configured VLAN (1-4093, no leading zeroes).

•Primary VLAN: The primary VLAN with which the selected VLAN is associated. (Note that this displays as VLAN 0 if the selected VLAN is itself a primary VLAN.)

•Ports List: The list of ports (and assigned type) in the selected private VLAN.

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.
