The layer 3 switch incorporates rich features, including VXLAN, MLAG, VRRP, etc. for scalable and flexible data center designs.

What Is a Layer 3 Switch?
A Layer 3 switch is a specialized hardware device used in network routing. Layer 3 switches technically have a lot in common with typical routers, and not only in physical appearance. Both can support the same routing protocols, inspect incoming packets, and make dynamic routing decisions based on the source and destination addresses inside. One of the main advantages of a Layer 3 switch over a router is in the way routing decisions are performed. Layer 3 switches are much low network latency since packets don't have to take additional steps through a router.

Layer-3 Switch is widely used in Data Centers and Universities, factory, enterprise where there is a very big setup of computer networking. Owing to its features like static and dynamic routing and its fast-switching speed than a router, it is used in LAN connectivity for interconnection of several VLAN and LAN networks.

L3D-2TX4806-40GF have the skills to offload the overloaded routers. This can be done by configuring a Layer-3 switch, each with a main router in a wide area networking scenario so that the switch can manage all the local level VLAN routing.

The Layer-3 switch in combination with a number of layer-2 switches supports more users to connect on the network without the need for implementation of an extra layer-3 switch and more bandwidth. Thus, it is widely implemented in universities and small-scale industries. In case if the number of end users on a network platform increases, then without any enhancement of the network, it can be accommodated in the same running scenario easily.

A Layer-3 switch is smart enough to handle and manage the routing and traffic controlling of locally connected servers and end devices utilizing its high bandwidth.

L3 multicast protocols is compliant with IGMPv1/v2/v3 and supports abundant multicast features such as IGMP v2/v3 snooping and fast leave. With Multicast VLAN Register (MVR), multicast receiver/sender control and illegal multicast source detect functions; L3D-2TX4806-40GF fiber series provides a great application experience for the customer.

The L3D-2TX4806-40GF supports Breakout cable for the 40G port. This feature is particularly significant as networks demand more flexibility and higher bandwidth capabilities. Breakout is a configuration that used the benefit of a high-bandwidth interface and "breaks it out" into multiple lower-bandwidth interfaces. Normally, this configuration applies to Ethernet switches where a high-speed port, such as a 40G QSFP+, is divided into multiple smaller connections, like 4x10G. This subdivision allows network engineers to connect to devices that require lower bandwidth connections while still fully and efficiently using the switch port resources. Breakout mode is an invaluable feature for data centers transitioning from 10G/25G to 40G/100G networks, as it provides backward compatibility and a smoother migration path. Flexibility: Breakout allows network builders a varied connectivity for there needs within their network. For example, they can connect switches with 10Gbps ports to a 40Gbps switch without needing to upgrade all equipment to support 40Gbps interfaces. Improved Port Utilization: Instead of leaving a high-speed port underutilized because there aren't enough devices that work at that speed, breakout mode allows the connection of more devices at lower speeds, thereby utilizing the port’s full capacity more effectively. Scalability: As network needs grow or change, breakout mode can help accommodate new devices and configurations without the need for immediate infrastructure rebuilds. This helps in growing the network in a cost-effective manner.

The AirLive L3D-2TX4806-40GF supports MLAG (multi-chassis link aggregation group) up to Max 63 Groups. MLAG is a non-standard protocol that implements link aggregation among multiple devices. The devices at both ends of the MLAG send MLAG negotiation packets through the peer-link. The main purpose of MLAG is to deliver system-level redundancy in the event one of the chassis fails. MLAG also a strong scalability as the capacity is not limited to a single device. This is very useful in those application were a network needs to be extended to accommodate more clients. MLAG networks can be expended without any downtime to the current existing network. Making it a very good solution for those location where downtime is not wanted. MLAG can be used at various places in the network to eliminate bottlenecks and provide resiliency.

MLAGs provide an active-active split aggregation deployment across two switches acting as one. MLAG creates a more resilient network with higher bandwidth capabilities. The below image shows a basic example of a MLAG Domain. In the example the peer switches are linked together with a special LAG (one or more cables as shown by the “Peer-Link” line in the picture, the peer link’s primary purpose is exchanging MLAG control information between peer switches. Any non-management port on the switch can be used in the Peer-Link. With the Peer-Link configured, the two switches appear as a single switch to partner switches upstream and downstream. Each partner switch contains MLAGs that are simply LAGs (link aggregation groups) whose cables are split between the two peers. Primary and secondary peer roles are chosen automatically by the program when MLAG is enabled.

Elevate your network’s performance and reliability with the cutting-edge Link Aggregation Control Protocol (LACP)—a smart technology designed to streamline your connectivity. LACP, a feature of the IEEE 802.3ad standard, is the key to unlocking seamless link aggregation, ensuring your network is robust and efficient.

The L3D-2TX4806-40GF provides 3 layers of VLAN interface, which is used to communicate with network layer devices. VLAN interface is a network layer interface, which can be configured with IP address. Before creating VLAN interface, the corresponding VLAN should be created first. With the help of VLAN interface, switches can communicate with other network layer devices. The ideal solution for enterprises, offers greater security, control and bandwidth conservation, and high-speed uplink. The L3D-2TX4806-40GF supports Guest VLAN, Voice VLAN and QinQ among others.

The L3D-2TX4806-40GF comes with Virtual eXtensible Local-Area Network, or VXLAN (network virtualization technology standard). It allows a single physical network to be shared by multiple different organizations, or “clients,” without any one client being able to see the network traffic of any other. In this way, VXLANs are a discrete, private network segment within a shared physical network.

a VXLAN allows a physical network to be segmented into as many as 16 million virtual, or logical, networks. It works by encapsulating Layer 2 Ethernet frames into a Layer 4 UDP packet alongside a VXLAN header. Because VXLANs are encapsulated inside a UDP packet, they can run on any network able to transmit UDP packets. The physical layout and geographic distance between nodes of the underlying network doesn’t matter, as long as the UDP data is forwarded from the encapsulating VXLAN Tunnel Endpoint to the decapsulating VXLAN Tunnel Endpoint.
 

ERPS (G.8032) is supported by the L3D-2TX4806-40GF Switch. ERPS supports multi-ring and multi-domain structures (master and sub rings) and optimizes the inspection mechanism in terms of two-way faults. In addition, it supports main device backups, load sharing and other work methods in <50ms switching.

This means that when multiple switches have been placed in a Ring and the network work is interrupted, it will recover within 50ms or less. Meaning the critical network like in Data centers, Campus networks or automated production lines will be online again with minimum loss of time. The ring network is also protected again loops.
