Multicast Filtering

Configuring IGMP Snooping and Query Parameters

You can configure the switch to forward multicast traffic intelligently. Based on the IGMP query and report messages, the switch forwards traffic only to the ports that request multicast traffic. This prevents the switch from broadcasting the traffic to all ports and possibly disrupting network performance.

Multicast routers use this information, along with a multicast routing protocol such as

DVMRP or PIM, to support IP multicasting across the Internet.

Command Usage

IGMP Snooping – This switch can passively snoop on IGMP Query and Report packets transferred between IP multicast routers/switches and IP multicast host groups to identify the IP multicast group members. It simply monitors the IGMP packets passing through it, picks out the group registration information, and configures multicast filters accordingly.

IGMP Query – A router, or multicast-enabled switch, can periodically ask their hosts if they want to receive multicast traffic. If there is more than one router/switch on the LAN performing IP multicasting, one of these devices is elected “querier” and assumes the role of querying the LAN for group members. It then propagates the service requests on to any adjacent multicast switch/ router to ensure that it will continue to receive the multicast service.

Command Attributes

• IGMP Status:

When enabled, the switch will monitor network traffic to determine which hosts want

 

to receive multicast traffic.

 

• This is also referred to as IGMP Snooping.

 

• Default: Enabled

 

 

• Act as IGMP Querier:

When enabled, the switch can serve as the Querier, which is responsible for asking

 

hosts if they want to receive multicast traffic.

 

• Default: Enabled

 

 

• IGMP Query Count:

Sets the maximum number of queries issued for which there has been no response

 

before the switch takes action to solicit reports.

 

• Default: 2

 

• Range: 2 - 10

 

 

• IGMP Query Interval:

Sets the frequency of time at which the switch sends IGMP host-query messages.

 

• Default: 125 secs.

 

• Range: 60 - 125 secs.

 

 

• IGMP Report Delay:

Sets the time (in seconds) between receiving an IGMP Report for an IP multicast

 

address on a port before the switch sends an IGMP Query out of that port and

 

removes the entry from its list.

 

• Default: 10

 

• Range: 5-30

 

 

• Query Timeout:

Sets the time (in seconds) the switch waits after the previous querier has stopped

 

querying before it takes over as the querier.

 

• Default: 300 seconds

 

• Range: 300 - 500

 

 

• IGMP Version:

Sets the protocol version for compatibility with other devices on the network.

 

• Default: 2

 

• Range: 1 - 2

 

 

1.All systems on the subnet must support the same version.

2.Some attributes are only enabled for IGMPv2, including IGMP Report Delay and IGMP Query Timeout.

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.
