Switches and Routers

ExtremeRouting SLX 9740

Next-Generation Fixed Form Router for Core Aggregation at Service Providers and Large Enterprise Data Centers

Product Highlights

  • High-density, fixed form factor Router with either 80 x 100 GbE or 40 x 100 GbE ports for ultra-high-end data centers and cross connections for Internet Exchange Points (IXPs)
  • Ultra-deep buffers of up to 16GB to ensure optimal performance to handle traffic in virtually any network for bursty traffic patterns
  • Fully featured Data Center Switch and Router with carrier-class MPLS, VXLAN, and Dual Stack IPv4/ IPv6 functionality
  • Integrated Application Hosting supports an open kernel-based virtual machine (KVM) environment to accommodate Extreme-provided or third-party customer specific applications, containers — with complete isolation from the networking operating system
  • Collapsed Campus Core with deep buffer and aggregation with fixed form factor switches with 10/25/40/100 GbE connections
  • BGP EVPN-VXLAN for Data Center Spine and Data Center Interconnect (DCI) networking

Increasingly, organizations are expanding from on-premise, private and hybrid cloud to full multi-cloud architectures to address agility, scale, security, reliability, and cost requirements as digital transformation reshapes their business environment. To succeed in the digital era, organizations need network platforms with the adaptability to address these rapidly evolving demands and enable them to simplify and scale operations while driving out cost.

The ExtremeRouting SLX 9740 Series platforms serve as demarcation between the enterprise networks and the service provider networks (internet) where the ISP connections terminate. Basic requirements include support for a full internet routing table, mainstream routing protocols BGP, OSPF and IS-IS, EVPN VxLAN, ACLs, BGP internet peering scale, MPLS, deep buffer, device management, and entry level DDoS protection.

Extreme Networks offers a choice for selecting the right routing solution to meet your business needs. The options include the SLX 9740 (1U) with 40 x 100 GbE ports and the SLX 9740 (2U) with 80 x 100 GbE ports to deliver cost effective solutions for the most demanding Enterprise and Service Provider customers.


Enterprise and Co-location datacenter consolidate on multiple layers with the SLX 9740 and can sit as an edge router above the datacenter network. With the use of MPLS or layer 3 protocols, the SLX 9740 links the datacenter gear to another datacenter or the outside world. Multi-Chassis Trunking (MCT) provides dynamic flow-based load balancing to multiple network nodes to enable resilient and high-performance networks.

The SLX 9740 is the industry's most powerful compact deep buffer dual stack IPv4/IPv6 Internet border router, providing a cost-efficient solution that is purpose-built for the most demanding service provider and enterprise data centers and MAN/WAN applications. The robust system architecture and a versatile feature set including IPv4, IPv6, and MPLS/VPLS, combined with Carrier Ethernet 2.0 and OAM capabilities, provides deployment flexibility. The SLX 9740 supports true internet scale border routing solutions with support for a maximum of 3.5M IPv4/IPv6 unicast routes.

The SLX 9740 can run third-party VM-based applications alongside the routing OS — all without impacting performance. This flexible and open solution enables organizations to deploy Extreme-provided or third-party applications and tools directly on the router. This design does not impact the control plane or forwarding of data traffic.

The ever-increasing growth of IXPs traffic with new record highs demand widespread 100 GbE connectivity at the edge of the network. Cost per port is a key factor as customers migrate from 10 GbE to 100 GbE, and ultra-high density is essential with the right mix of technologies (e.g., VPLS and EVPN) with the SLX 9740.

The SLX 9740 is designed to cost-effectively deliver the scale and performance needed to address the explosive growth in network bandwidth, devices, and services — today and well into the future. This flexible platform, powered by Extreme SLX-OS, provides carrier-class advanced features that leverage proven Extreme routing, MPLS, Carrier Ethernet, and VXLAN overlay technology currently deployed in the most demanding service provider, data center, and enterprise networks.

The SLX 9740 offers a deep buffering platform that is purpose-built for the most demanding service provider and enterprise networks. The border router is the interconnection point between internal networks and the internet. With more traffic moving across these routers, there is added demand for capacity, the ability to absorb speed mismatches and handle microbursts without compromising performance. The SLX 9740-40C has 8GB and SLX 9740-80C has 16GB of deep packet buffers.
