The Arista software platforms, EOS and CloudVision, are designed to provide flexibility both in the choice of the appropriate feature functionality and in the software consumption model. The base feature set of Arista EOS comes bundled with the Arista products and systems. A set of feature licenses are available to enable additional functionality in advanced feature sets.

The traditional licensing procurement model employs a perpetual term for the right to use the feature, set at a fixed price. For Arista CloudVision and vEOS Router, the functionality is available as a monthly subscription, for an agreed upon term.

The following diagrams depict the two primary groupings for the advanced feature sets:


EOS Licensing Figure 1

Figure 1: Software Procurement Approach

  • Routing: General Routing functionality (BGP, Multicast, etc) is available in the E license. The FLX Lite license expands that to include key features like BGP-EVPN for VXLAN. The FLX license is the superset that also includes larger routing tables and MPLS features. See the EOS Platform Licensing tab for specifics.
  • Automation/Visibility: CloudVision is the most complete offering for advanced automation and visibility. Arista also offers subsets of that offering with CloudVision Lite, for entry-level GUI functionality, and the Z license for discrete APIs and visibility tools. See the Automation/Visibility tab for specifics. Agility through EOS Extensions and Partner Integration: The V2 license includes capability to run custom extensions natively or via containers in EOS. In addition, the V2 license gives customers an option of integrating with Arista’s best of breed ecosystem for security, analytics, visibility, and other use-cases.
  • Multi Cloud / Cloud Native: CloudEOS is Arista’s multi cloud and cloud native networking solution enabling a highly secure and reliable networking experience with consistent segmentation, telemetry, provisioning and troubleshooting for the entire enterprise. See the CloudEOS tab for specifics.


Arista EOS offers a broad range of advanced features through the feature sets shown in diagram below.

Figure 1: Software license to feature mapping

EOS licenses are offered as perpetual licenses applied on a per-system basis. Customers can choose the appropriate license, as shown in figure 1, based on the features required for the profile for which the system is to be deployed. The Platform to License SKU mapping is available here.

Arista CloudVision is built on a term-based software subscription licensing model. The CloudVision licenses are platform independent, with no mapping to any particular hardware device SKUs. There are two tiers of CloudVision Licenses available - CloudVision and CloudVision Lite. CloudVision the full feature set, including full analytics, telemetry, provisioning, and the Z and V2 features. CloudVision Lite is a subset of the Premier capabilities, providing a functional graphical user interface (GUI) for base visibility and network management. The feature sets for these licenses are defined below in Figure 2.

EOS offers extensive automation and integration capabilities for customers looking to advanced visibility and automation features directly. Customers can deploy automation, custom extensions and integrate existing analytics and/or security systems with the Z and ‘V2’ licenses. The feature sets for these licenses are defined below in Figure 3.

CloudEOS Router VM

CloudEOS Router VM is offered in each cloud provider marketplace under either a pre-purchased Bring-Your-Own-License (BYOL) subscription model or via Pay-As-You-Go (PAYG) hourly or annual consumption-based billing. It is also available for download for on-premise use via Arista’s Software Downloads page as BYOL only. For more details, please refer to CloudEOS Router VM datasheet.

Pay-As-You-Go (PAYG) Consumption Model

Under PAYG model, customers will be charged software subscription fees based on hourly or annual usage rates that have been set for the product. PAYG billing will be done via the cloud provider billing cycle. A benefit of the PAYG model is that the customers can start using CloudEOS Router immediately and pay only for the amount that they consume. Note that PAYG consumption does not require the customers to obtain a quote, generate a purchase order or to manage licenses, making it the preferred and de facto consumption model for most public cloud resources.

Bring-Your-Own-License (BYOL) Purchase Model

Under the BYOL model, customers will need to purchase monthly subscription SKUs from Arista in order to activate and use the CloudEOS Router. The BYOL customer will pay Arista directly for the subscription in advance and will be provided with license activation keys and proof of entitlement for the term of their subscription.

CloudEOS Router Container

CloudEOS Router Container is offered in on-premises Kubernetes deployment under Bring-Your-Own-License (BYOL) monthly subscription model. For more details, please refer to CloudEOS Router Container datasheet.

Arista EOS as Subscription (EaaS) Licensing Model

The Arista EOS as a Subscription (EaaS) licensing is an alternative procurement model from traditional bundled licenses. It is designed for customers looking for OpEx and CapEx payment flexibility.

With Arista EaaS, EOS software is licensed as a monthly subscription. EaaS is available for a limited set of Arista switches, which are available as “hardware-only” items. These hardware-only items include 3 years of Next-Business Day hardware replacement.

EaaS is available as a choice of two feature sets: EaaS and EaaS+CloudVision.

The EaaS License includes all available EOS base and the set of advanced features (Baseline, E, V and Z), and includes 24x7 software A-Care support. This license does not include any additional CloudVision functionality.

The EaaS+CloudVision licenses include all EOS base and advanced features and the completed CloudVision feature set. The EaaS+CloudVision license also includes with 24x7 software A-Care support.

Currently, EaaS is available on following platforms:

7050TX-48 7160-32CQ
7050SX-64 7160-48YC6
7050TX-64 7160-48TC6
7050TX-128 7050QX-32S
7050SX-128 7280SR-48C6

The following software license SKUs are available for EaaS

SS-EOS-Enh-FIX1-1M EOS Subscription for 1-Month includes EOS E/V/Z/FLX-LITE Licenses and ACare SW for 1RU systems
SS-EOS-Enh-FIX2-1M EOS Subscription for 1-Month includes EOS E/V/Z/FLX-LITE Licenses and ACare SW for 2RU systems
