Link Aggregation Commands

Ports can be statically grouped into an aggregate link (i.e., trunk) to increase the bandwidth of a network connection or to ensure fault recovery. Or you can use the Link Aggregation Control Protocol (LACP) to automatically negotiate a trunk link between this switch and another network device. For static trunks, the switches have to comply with the Cisco EtherChannel standard. For dynamic trunks, the switches have to comply with LACP. This switch supports up to six trunks. For example, a trunk consisting of two 1000 Mbps ports can support an aggregate bandwidth of 4 Gbps when operating at full duplex.

Guidelines for Creating Trunks

General Guidelines:

Finish configuring port trunks before you connect the corresponding network cables between switches to avoid creating a loop.

A trunk can have up to eight ports.

The ports at both ends of a connection must be configured as trunk ports.

All ports in a trunk must be configured in an identical manner, including communication mode (i.e., speed, duplex mode and flow control), VLAN assignments, and CoS settings.

All the ports in a trunk have to be treated as a whole when moved from/to, added or deleted from a VLAN via the specified port-channel.

STP, VLAN, and IGMP settings can only be made for the entire trunk via the specified port- channel.

Dynamically Creating a Port Channel:

Ports assigned to a common port channel must meet the following criteria:

Ports must have the same LACP system priority.

Ports must have the same port admin key (Ethernet Interface).

If the port channel admin key (lacp admin key - Port Channel) is not set when a channel group is formed (i.e., it has the null value of 0), this key is set to the same value as the port admin key (lacp admin key - Ethernet Interface) used by the interfaces that joined the group.

However, if the port channel admin key is set, then the port admin key must be set to the same value for a port to be allowed to join a channel group.

If a link goes down, LACP port priority is used to select the backup link.

Default Setting: The current port will be added to this trunk.

from a trunk.

 

Command Mode: Interface Configuration (Ethernet)

 

Command Usage: When configuring static trunks, the switches must com-

 

ply with the Cisco EtherChannel standard.

 

• Use no channel-group to remove a port group from a trunk.

 

• Use no interfaces port-channel to remove a trunk from the switch.

 

Example: The following example creates trunk 1 and then adds port 11:

 

Console(config)#interface port-channel 1

 

Console(config-if)#exit

 

Console(config)#interface ethernet 1/11

 

Console(config-if)#channel-group 1

 

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.
