The Extreme 7720 are purpose-built switches designed for high-performance aggregation and core applications. As a universal hardware platform, the 7720 provides end-to-end secure network segmentation, in addition to advanced policy capabilities, with a user-selectable choice of Extreme’s flagship switch operating systems. This makes the 7720 a uniquely flexible platform that can be deployed in a variety of aggregation and core environments.

The Extreme 7720 network hardware platform enables organizations to design networks that accommodate a variety of applications and east-west traffic patterns. With its high-density scale-out architecture, leading power efficiency, and airflow options, the 7720 platform delivers a cost-effective solution that optimizes power, cooling, and equipment room space, wherever your network operating center might be.

One model of the 7720 is available with the following port capacity.


• 32 x 40Gb/100Gb QSFP28 fiber ports


The 7720 supports a variety of Ethernet Fabric services, including Extreme’s Fabric Connect when running Fabric Engine (VOSS) and Extreme’s IP Fabric when running Switch Engine (EXOS). It also supports Fabric Attach for automated connection to either Layer 2 or Layer 3 fabric services. Extreme’s Fabric Connect and IP Fabric on the 7720 enable the creation of virtualized networks that automate network operations, simplify network provisioning, and enhance security, all while reducing the strain on network and IT personnel.

Two of the 7720’s QSFP28 uplink ports can be used for high-speed 400Gb stacking when running Switch Engine (EXOS). Up to eight systems can be stacked using qualified direct attach cables and/or optical transceivers. (Note: Stacking is not supported when running Fabric Engine (VOSS)).

The 7720 can be managed by ExtremeCloud IQ and ExtremeCloud IQ-Site Engine for comprehensive unified management with a consolidated view of users, devices and applications across wired and wireless networks.

Zero-touch provisioning from ExtremeCloud IQ lets one quickly bring new 7720 switches online as well as enable the selection of the operating system (OS) persona. Alternatively, 7720 on-box management can be done manually via a web-based GUI or generic CLI.

The 7720 Series comes with a dual-persona capability allowing user choice of the switch operating system (OS). Either the Switch Engine (EXOS) or Fabric Engine (VOSS) persona can be enabled on 7720 hardware models. The desired persona can be selected at start-up or changed at a later stage. Once selected, the 7720 assumes the features/capabilities of the selected OS.

7720 persona activation can be done manually at boot-up, including via the system CLI. Or, it can be automated by pre-provisioning the 7720 persona in ExtremeCloud IQ. When first booted, the 7720 automatically connects to ExtremeCloud IQ to find its persona. The pre-provisioned OS persona is then remotely enabled on the 7720 system – eliminating the need for manual selection.
