Link Aggregation: Boost the Connection Between a Router and a NAS

Thank you for taking the time to respond. Was this article helpful? Link aggregation allows you to combine multiple Ethernet links into a single logical link between two networked devices. The most common device combinations involve connecting a switch to another switch, a server, a network attached storage NAS device, or a multi-port access point. Network devices and management functions treat the link aggregation group LAG of multiple Ethernet connections as a single link. The two primary types of LAGs are static also known as manual and dynamic. Linux-based devices, such as NETGEAR ReadyNAS storage devices, often offer several additional types of link aggregation that provide increased fault tolerance or load balancing instead of increased bandwidth. You still need to configure the LAG on each device, but LACP helps prevent one of the most common problems that can occur during the process of setting up link aggregation: misconfigured LAG settings. This helps to minimize packet loss. The following instructions describe in general terms how to set up link aggregation between two devices in your network. To set up link aggregation between two devices in your network:. Do not connect the devices to each other using more than one Ethernet cable until after you set up the LAG on each device. If you form multiple connections between the two devices and neither device has loop prevention, you create a network loop. Network loops can slow or stop normal traffic on your network. Advanced remote support tools are used to fix issues on any of your devices. The service includes support for the following:. Thank You Thank you for taking the time to respond.

Link aggregation is sometimes called by other names: Ethernet bonding Ethernet teaming Link bonding Link bundling Link teaming Network interface controller NIC bonding NIC teaming Port aggregation Port channeling Port trunking The most common device combinations involve connecting a switch to another switch, a server, a network attached storage NAS device, or a multi-port access point. Unmanaged switches do not support link aggregation. What are the benefits of link aggregation? Link aggregation offers the following benefits: Increased reliability and availability. If one of the physical links in the LAG goes down, traffic is dynamically and transparently reassigned to one of the other physical links. Better use of physical resources. Traffic can be load-balanced across the physical links. Increased bandwidth. The aggregated physical links deliver higher bandwidth than each individual link. Cost effectiveness.

What are link aggregation and LACP and how can I use them in my network?


Link aggregation LAG is used to describe various methods for using multiple parallel network connections to increase throughput beyond the limit that one link one connection can achieve. For link aggregation, physical ports must reside on a single switch. Link aggregation is a technique used in a high-speed-backbone network to enable the fast and inexpensive transmission of bulk data. The best feature of link aggregation is its ability to enhance or increase the network capacity while maintaining a fast transmission speed and not changing any hardware devices, thus reducing cost. LAG is a very common technique for establishing a new network infrastructure using extra cabling above the current requirements. Labor cost is much more than the cost of cabling. Thus, when a network extension is required, the extra cables are used without incurring any additional labor. However, this can be done only when extra ports are available. This is the best feature of LAG. A communication system keeps working even when a link fails. In such situations, link capacity is reduced but data flow is not interrupted. Formerly, there were many techniques used for networking, but IEEE standards are always preferred. LAG supports network load balancing. Different load balancing algorithms are set by network engineers or administrators. Furthermore, network speed is increased by small increments, saving both resources and cost.

How To Set Up NIC Teaming (Link Aggregation)


There are times when having a bit more performance is better. Actually, who are we kidding? Having more performance is always better. In the case of networking, this is especially true. You can never have enough bandwidth. There will be some, though, who argue that x number of megabits or gigabits per second is "more than enough. All of today's motherboards ship with at least one gigabit Ethernet port. Some premium boards come with two. Of course, you can always add more by installing add-in NICs, and there are motherboards with more than two, but for the sake of this article we're referring to consumer motherboards. So, what exactly is link aggregation? In a nutshell, link aggregation or trunkingis the fine, delicate art of combining two or more physical Ethernet links into a single logical link. Note that we use the phrase "aggregated bandwidth. Think of link aggregation in terms of network link resiliency rather than total available throughput. In that sense, if one physical part of the logical link fails, traffic will failover to the remaining active links. Where you will see increased bandwidth is when you have multiple origin-destination IOs. Start two file transfers, however, and you'll see the benefits of aggregated bandwidth. In simple terms, link aggregation increases the number of lanes on a highway but it doesn't increase the speed limit. What this equates to is if you want true higher throughput, moving to a fatter pipe—like 10GbE—is the only way to go. For the majority of home networks, setting up link aggregation serves little to no advantages. However, if you're employing a NAS that has multiple Ethernet ports, it may support link aggregation and you'll have some benefits there. So, how do you do it in a network? Unfortunately, most consumer-level switches and routers do not support link aggregation, so you'll have to link into business-level products, which will carry a premium. Second, your PC needs to have two Ethernet ports, and whatever device you want to connect to needs to have at least the same.

What is “link aggregation” and how does it benefit your network?


What about link redundancy and failover with your existing Ethernet device? Link aggregation LAG is a technique used on Ethernet switches to enable the fast and inexpensive transmission of bulk data. Link aggregation enhances or increases the network capacity while maintaining a fast transmission speed while not investing in additional hardware or communications links, thus reducing cost. Link aggregation LAG is used to describe various methods for using multiple parallel network connections to increase throughput beyond the limit that one link one connection can achieve. For link aggregation, physical ports must reside on a single switch. Combining can either occur such that multiple interfaces share one logical address i. IP or one physical address i. MAC addressor it allows each interface to have its own address. If it finds a device on the other end of the link that also has LACP enabled, it will also independently send frames along the same links enabling the two units to detect multiple links between themselves and then combine them into a single logical link. LACP can be configured in one of two modes: active or passive. In active mode it will always send frames along the configured links. Some claim that the most important feature of link aggregation is link failover. With link failover, traffic from a failed link can be switched over to working links in the aggregation. For security purposes, data is transmitted over the usual link and the other link in the aggregation sits idle or can transmit data from another physical link. If the first link goes down, a signal is sent to the second link to take over data transmission. In this situation, the second link can be set to either continue taking on data from both streams at a slower transmission rate or it can be set to prioritize which data has a higher priority. Using link aggregation is an efficient, cost effective way to acquire better bandwidth when needed and always provide a failover.

Link aggregation: A cool tip for better bandwidth & redundancy on Ethernet switches

When it comes to networking, a wired connection is always the best one. When one connection isn't enough however, link aggregation or bonding two network connections together can boost throughput. Games don't use much bandwidth so a 1 gigabit connection is enough, but link aggregation can help with file transfers. While faster 10 Gbps standards for Ethernet are on the market, affordable consumer level equipment remains quite scarce. In this time of transition from 1 Gbps to 10 Gbps wired Ethernet, a more available, and affordable strategy to consider is Link Aggregation, which also goes by the names of link bundling, and port aggregation. This is a method to combine multiple individual Ethernet connections, into one logical link. Before you think this is just the latest internet hack, realize that link aggregation is a standard of the IEEE, first debuting in the year as It was then revised in to Also realize that Link Aggregation is a general wired network upgrade, and well worth exploring for the reasons enumerated above. There are clear benefits, particularly in a loaded and congested network. The first is for the network backbone. When running Ethernet cable to connect a switch to a router, as the cables are comparatively inexpensive, and the labor costs are high, it is good practice to run multiple cables in this scenario just to make sure there is always some connection. Using Link Aggregation it is simple to have these multiple Ethernet connections to act as one logical connection, hardening the network in case a wire fails, and increasing total bandwidth when all the wires are functioning. For our setup we used, the Trendnet TEGWS switch to aggregate multiple ports into a single logical connection between our wired devices. The trick to setting up this switch, and others is making sure the switch and the router are on the same network. The other way to use Link Aggregation is to a client. In this case, a special NIC is required that supports multiple Ethernet connections, as most motherboards have only a single Ethernet port, and do not support Link Aggregation.
