The Virtual Services Platform (VSP) 4900 Series is the next generation of Extreme Fabric Connect fixed-form factor switches designed for network edge and aggregation deployments. Available in four models to address a range of campus, remote site, and multiservice needs, the 4900 Series enables end-to-end fabric services from network edge to aggregation to core, as well as transparent extension of fabric services to the branch.

Multiple models support 1GbE 30W PoE, 1Gb or 10GbE SFP/SFP+ fiber, and 1GbE, 2.5GbE, 5GbE, or 10GbE multirate 60W PoE access ports. With modular uplink support at 10Gb, 25Gb, and 40Gb, VSP 4900 switches can be linked to other switches or devices over a range of media. This provides high-performance, resilient, and secure Gigabit and multi-Gigabit Ethernet connectivity, enabling VSP 4900 switches to leverage advanced capabilities that enable full-featured network virtualization to be flexibly deployed across a range of network environments.


The VSP 4900 Series supports advanced Layer 3 services, including IPv4 and IPv6 dynamic routing as well as IP multicast services. This enables it to satisfy conventional IP routing deployments in addition to its fabric-based services.

VSP 4900 models support Distributed Virtual Routing (DVR) leaf services, IP routing technologies (such as RIPv1/2, RIPng, and OSPFv2/v3), as well as multicast services (such as PIM-SM/ SSM, IGMP v1, 2, and 3) and Fabric Connect to PIM gateway.

The VSP 4900 Series can be managed by ExtremeCloud IQ and ExtremeCloud IQ — Site Engine for centralized switch management, giving you a consolidated view of users, devices, and applications across wired and wireless networks. ExtremeCloud IQ enables zero-touch provisioning, allowing you to quickly bring new VSP 4900 switches online and a granular view that enables efficient inventory and network topology management.

Alternatively, VSP 4900 on-box management can be done manually via a web-based GUI or generic command-line interface (CLI).

The VSP 4900 Series natively supports Extreme Fabric Connect technology, offering you the ability to create a virtualized network that simplifies network provisioning and reduces strain on network and IT teams based on an extended implementation of the Shortest Path Bridging standards of IEEE 802.1aq. Fabric Connect delivers an edge-only provisioning model that seamlessly integrates with orchestration and automation, eliminates the need to configure network-wide VLANs, and removes the risk of network loops.

The VSP 4900 also natively supports Fabric Extend, a feature of Fabric Connect that extends Fabric Connect’s simplified provisioning and virtualization services over an intermediate, Layer 2 or Layer 3-based third-party network. For example, Fabric Extend allows you to connect two Fabric Connect environments or islands over a Service Provider WAN, such as MPLS or Ethernet WAN.

Select VSP 4900 models support Extreme's Integrated Application Hosting, which leverages the switch’s hardware and software design to extend services without impacting switch or network performance. VSP4900-12MXU-12XE and VSP4900-24XE models can run a Guest VM directly on the switch, supporting Extreme or third-party applications and tools for real-time visibility or to meet specific business or operational needs. This can help improve network visibility and performance while reducing operational costs.

IEEE 802.1AE MACsec is supported on VSP 4900 Series access and modular uplink ports, enabling the encryption and decryption of packets between connected switches or devices. As a link-only encryption, 4900 switches can still apply services to the packet, such as policy or QoS, without compromising the security of packets across the link. With 128-bit and 256-bit Advanced Encryption Standard (AES) support, the VSP 4900 provides the most secure link encryption.

Select VSP 4900 models support PoE that conforms to IEEE standards to address the needs of powered edge devices. VSP 4900-48P model supports IEEE 802.3at 30W PoE on each of its 48 ports, while the VSP 4900-12MXU-12XE model supports IEEE 802.3bt 60W PoE on its 12 multirate ports. In addition, both these models support fast and perpetual PoE capabilities for faster startup and more continuous operation of connected, PoE-powered endpoints.

The VSP 4900 supports Versatile Interface Modules (VIM) for its uplink ports as well as its single VIM slot available for uplinks. VIM options include two- and four-port modules that support 10Gb, 25Gb, and 40Gb data rates.
