The Virtual Services Platform (VSP) 7400 Series are space-efficient, high-performance Ethernet switches, available delivering wire-speed 100 Gigabit and 25Gb Ethernet connectivit y. Supporting a range of interface speeds, including 1Gb, 10 Gb, 25Gb, 40 Gb and 100 Gb, all in a compact 1RU form factor, the VSP 7400 Series can be flexibly deployed in either core/ aggregation or spine/ leaf high-density top-of-rack architectures. It also supports Extreme Fabric Connect for simplified, automated network services delivery.Two models of the VSP 7400 Series are available:VSP7400 -32C:Core or spine switch with 32 x 100 Gb QSFP28 ports. QSFP28 ports can also be optionally run at 10 Gb, 25Gb or 40 Gb with channelization for high-density applications.VSP7400 -48Y-8C:Aggregation or leaf switch with 48 x 25Gb SFP28 port s and 8 x 100 Gb QSFP28 uplink ports. SFP28 ports on the VSP7400 -48Y can also run at 1Gb, 10 Gb or 25Gb to support a range of connectivity options. The VSP 7400 can handle a variety of high bandwidth applications, including high-density 10 Gb, emerging 25Gb, as well as 40 Gb and 100 Gb core/ aggregation and spine/ leaf fabric deployments. A variety of QSFP28, QSFP+, SFP28 and SFP+ transceivers are also available to support a range of fiber interface needs.Extreme Fabric Connect:The VSP 7400 Series natively supports the Extreme Fabric Connect technology. Based on an extended implementation of Shortest Path Bridging (SPB) standards of IEEE 802.1aq and IETF RFC 6329, Fabric Connect offers the ability to create a simplified virtualized network that simplifies network provisioning and reduces the strain on network and IT personnel. Benefit s include: Eliminates need to configure network-wide VLANs Replaces legacy protocols with a single unified protocol Removes the risk of network loops Delivers an edge-only provisioning model that seamlessly integrates with orchestration and automation Supports both L2 and L3 virtualization, including IP multicast routing Traditionally, provisioning new network services required engineers to touch every device in the service path, configuring each device to enable both the active and redundant links. The bigger the network the more complex this task becomes.Leveraging Fabric Connect delivers fundamental change. Rather than the network appearing as a mass of individual devices, it becomes a single cloud, so that engineers only need to touch the unique device that is providing service directly to the end-point. Fabric Connect instantly propagates all the end-points service attributes to every other node within the fabric.Specific Fabric Connect features supported on the VSP 7400 Series include: L2 Virtual Service Networks (VSNs), Layer 3 Virtual Service Networks, Inter-VSN Routing, IPv4/ IPv6 IP Shortcuts, IP Multicast over Fabric Connect, Fabric Extend and Fabric Attach Server.Advanced Layer 3 Services: The VSP 7400 Series also supports advanced Layer 3 services that enable it to satisfy conventional IP routing deployments, in addition to its fabric-based services. Layer 3 services include IPv4 and IPv6 dynamic routing, as well as IP multicast services. Specific IP routing technologies supported include RIPv1/ 2, RIPng, OSPFv2/ v3, BGP/ BGP+ and VRF. Multicast services include PIM-SM/ SSM, IGMP v1/ v2/ v3, as well as Fabric Connect to PIM gateway. The VSP 7400 also supports Distributed Virtual Routing (DvR) and VXLAN Gateway services.
