Data Center Switch with L3 Features and Super High Speed
The AirLive L3D-10XGF26-100GF offers high performance full 24 port 10G SFP+ and 2x 100G QSFP28 uplink ports in a compact 1U form factor. The AirLive L3D-10XGF26-100GF is ideal for Data Centers, and large network users like campus. Combining advantages of zero packet loss, low latency, and non-blocking performance for lossless Ethernet. The layer 3 switch incorporates rich features, including EVPN-VXLAN, MLAG, VRRP, OSFP etc. for scalable and flexible data center designs, redundant hot-swappable power supplies and fans for high availability and security.

The L3D-10XGF26-100GF supports Breakout cable for the 100G 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 100G QSFP28, is divided into multiple smaller connections, like 4x25G. 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 100Gbps switch without needing to upgrade all equipment to support 100Gbps 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 L3D10XGF26-100GF supports MLAG (multi-chassis link aggregation group). 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.

The L3D-10XGF26-100GF 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. When combined with an Ethernet virtual private network (EVPN)—which transports Ethernet traffic in virtualized networks using WAN protocols—VXLAN allows Layer 2 networks to be extended across a Layer 3 IP or MPLS network.

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.

When VXLAN is combined with EVPN, administrator can create virtual networks out of physical network ports on any physical network switches that support the VXLAN/EVPN standard and are part of the same Layer 3 network. For example, you could take a port from switch A, two ports from switch B, and another port from switch C and build a virtual network that appears to all the connected devices as a single physical network. Devices participating in this virtual network would be unable to see traffic in any other VXLANs or the underlying network layout.

The AirLive L3D-10XGF26-100GF comes with dual power supplies and smart fans by default, providing high availability and longevity. 1+1 Dual AC PSU 350W, PSUs can be removed/replaced without shutting down the system (Hot-swappable). 2 Hot-swappable Fan Modules, Variable-speed fans for superior cooling, noise and power reduction. Support automatic fan temperature control, temperature monitoring, and fan alarm.
