VLAN Configuration

Adding Static Members to VLANs - CLI

This example adds Port 3 to VLAN 1 as a tagged port, and removes Port 3 from VLAN 2.

Configuring VLAN Behavior for Interfaces

You can configure VLAN behavior for specific interfaces, including the default VLAN identifier (PVID), accepted frame types, ingress filtering, GVRP status, and GARP timers.

Command Usage

GVRP – GARP VLAN Registration Protocol defines a way for switches to exchange VLAN information in order to automatically register VLAN members on interfaces across the network. GARP – Group Address Registration Protocol is used by GVRP and GMRP to register or deregister client attributes for client services within a bridged LAN. The default values for the GARP timers are independent of the media access method or data rate. These values should not be changed unless you are experiencing difficulties with GMRP or GVRP registration/deregistration.

Command Attributes

• PVI:

VLAN ID assigned to untagged frames received on the interface.

 

• Default: 1

 

• If an interface is not a member of VLAN 1 and you assign its PVID to this VLAN, the

 

interface will automatically be added to VLAN 1 as an untagged member. For all

 

other VLANs, an interface must first be configured as an untagged member before

 

you can assign its PVID to that group.

 

 

• Acceptable Frame

Sets the interface to accept all frame types, including tagged or untagged frames, or

Type:

only tagged frames.

 

When set to receive all frame types, any received frames that are untagged are

 

assigned to the default VLAN.

 

• Option: All, Tagged

 

• Default: All

 

 

• Ingress Filtering:

If ingress filtering is enabled, incoming frames for VLANs which do not include this

 

ingress port in their member set will be discarded at the ingress port. However, they

 

do affect VLAN dependent BPDU frames, such as GMRP.(Default: Disabled)

 

• Ingress filtering only affects tagged frames.

 

• If ingress filtering is disabled and a port receives frames tagged for VLANs for which

 

it is not a member, these frames will be flooded to all other ports (except for those

 

VLANs explicitly forbidden on this port).

 

• If ingress filtering is enabled and a port receives frames tagged for VLANs for which

 

it is not a member, these frames will be discarded.

 

• Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP or

 

STP. However, they do affect VLAN dependent BPDU frames, such as GMRP.

 

 

• GVRP Status:

Enables/disables GVRP for the interface. GVRP must be globally enabled for the

 

switch before this setting can take effect. (See the Displaying Bridge Extension

 

Capabilities section on page 27.)

 

When disabled, any GVRP packets received on this port will be discarded and no

 

GVRP registrations will be propagated from other ports.

 

• Default: Disabled

 

 

• GARP Join Timer:

The interval between transmitting requests/queries to participate in a VLAN group.

 

• Range: 20-1000 centiseconds

 

• Default: 20

 

• Timer settings must follow this rule: 2 x (join timer) < leave timer < leaveAll timer

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.
