Command

Function

 

 

switchport gvrp

Syntax:

This command enables

[no] switchport gvrp

GVRP for a port.

Default Setting: Disabled

Use the no form to disable it.

Command Mode: Interface Configuration (Ethernet, Port Channel)

 

Example:

 

Console(config)#interface ethernet 1/6

 

Console(config-if)#switchport gvrp

 

Console(config-if)#

 

 

switchport forbidden vlan

See page 258.

 

 

show gvrp configuration

Syntax:

This command shows if

show gvrp configuration [interface]

GVRP is enabled.

• interface

 

ethernet unit/port

 

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

 

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

 

port-channel channel-id (Range: 1-4)

 

Default Setting: Shows both global and interface-specific configuration.

 

Command Mode: Normal Exec, Privileged Exec

 

Example:

 

Console#show gvrp configuration ethernet 1/6

 

Eth 1/ 6:

 

GVRP configuration: Enabled

 

Console#

 

 

garp timer

Syntax:

This command sets the

garp timer {join leave leaveall} timer_value

values for the join, leave and

no garp timer {join leave leaveall}

{join leave leaveall} - Which timer to set.

leaveall timers.

• timer_value - Value of timer.

Use the no form to restore the

Ranges:

timers’ default values.

• join: 20-1000 centiseconds

 

 

• leave: 60-3000 centiseconds

 

• leaveall: 500-18000 centiseconds

 

Default Settings:

 

• join: 20 centiseconds

 

• leave: 60 centiseconds

 

• leaveall: 1000 centiseconds

 

Command Mode: Interface Configuration (Ethernet, Port Channel)

 

Command Usage: 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.

 

• Timer values are applied to GVRP for all the ports on all VLANs.

 

• Timer values must meet the following restrictions:

 

leave >= (2 x join)

 

leaveall > leave

 

Set GVRP timers on all Layer 2 devices connected in the same network to the

 

same values. Otherwise, GVRP may not operate successfully.

 

Example:

 

Console(config)#interface ethernet 1/1

 

Console(config-if)#garp timer join 100

 

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.
