Designed to extend the reach of Extreme Fabric Connect technology to the branch and network edge, the Virtual Services Platform (VSP) 4900-48P delivers fully featured network virtualization capabilities in a cost-effective Ethernet platform. Optimized for small sites, the VSP 4900-48P offers full multi-service capabilities in a compact form factor and provides a simplified, streamlined way to build and manage networks.
The VSP 4900-48P provides 48 ports of 10/100/1000Mb Ethernet along with 30W Power over Ethernet (PoE). It also includes modular uplink options – at 10Gb, 25Gb and 40Gb – for flexible linkage to other switches or devices over a range of media. It further delivers a full set of Extreme Fabric Connect capabilities to enable simplified, automated network services delivery.
The VSP 4900 is ideal for small sites where there’s a need to extend Extreme Fabric Connect technology across the wide area, the metro, or to the campus edge. In these scenarios, the VSP 4900 can help segment traffic for regulatory or security reasons or to support multiple entities or tenants. For these types of deployments, the VSP 4900 delivers a rich set of multi-service/multi-tenant functionality – all in cost-effective hardware platform.
The VSP 4900 can be deployed in conjunction with other Extreme Fabric Connect platforms or switches to simplify the network, streamline operations, lower costs and help businesses gain a competitive edge.
Extreme Fabric Connect
The VSP 4900 natively supports the Extreme Fabric Connect technology. Based on an extended implementation of the 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. Benefits 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-point’s service attributes to every other node within the fabric.
Specific Fabric Connect features supported on the VSP 4900 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.
The VSP 4900-48P natively supports Fabric Extend which enables it to extend Fabric Connect services over an intermediate 3rd-party network, whether Layer 2 or Layer 3-based. With Fabric Extend, enterprises can, for example, connect two Fabric Connect environments (or islands) over a Service Provider WAN, such as MPLS or Ethernet WAN. Fabric Connect simplified provisioning and virtualization services are transparently extended across the 3rd-party network.
Advanced Layer 3 Services
The VSP 4900 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 4900 also supports Distributed Virtual Routing (DvR) leaf services.
Power Over Ethernet
The VSP 4900-48P provides standards-based IEEE 802.3at (30W) Power over Ethernet (PoE) on its 48 x 1Gb ports. This enables it to address the needs of powered edge devices, while eliminating the need for additional electrical cabling and circuits. In addition, the VSP 4900 provides the following capabilities to address the advanced needs of powered edge devices:
- Perpetual PoE which enables PoE power to be maintained during a switch re-start, preventing attached powered devices from being disrupted or rebooted during the switch reset
- Fast PoE which enables power to be supplied to connected edge devices before switch boot-up completion, speeding the time for powered end-points to start up
VIM Options for Flexible Uplinks
The VSP 4900 supports Versatile Interface Modules (VIM) for its uplink ports and has a single VIM slot that can be optionally used for this purpose. VIM options include 2 and 4-port modules that support 10Gb, 25Gb and 40Gb data rates.
MACsec Link Encryption
The VSP 4900 supports IEEE 802.1AE MACsec on its 10/100/1000 access ports, as well as on its modular uplink ports. MACsec is a hop-by-hop security capability which encrypts/decrypts packets between connected switches or devices. As a link-only encryption, the switches can still apply services to the packet, such as policy or QoS, without compromising the security of packets across the link. With support for both 128-bit and 256-bit Advanced Encryption Standard (AES) support, the VSP 4900 provides the most secure link encryption.
Application Telemetry is a unique feature of ExtremeAnalytics that enables the ExtremeSwitching infrastructure to participate in the forwarding and analysis of network application flows. By combining packet flow information from the VSP 4900 along with the deep packet inspection abilities of ExtremeAnalytics, actionable insights into network and application performance can be provided. This all without the need for expensive sensors or collectors.
The VSP 4900 can be managed in a variety of ways. Simple on-box management functions are delivered by a web-based GUI and a generic CLI is available for manual configuration. For centralized management, the Extreme Management Center (XMC) delivers a comprehensive unified management capability. XMC provides a consolidated view of users, devices and applications for wired and wireless networks – from data center to edge. A granular view of users, devices and applications with an easy to understand dashboard enables efficient inventory and network topology management.
