Aviz Networks outlines FTAS 3.1 updates for SONiC testing

Aviz Networks released FTAS 3.1, adding automated test cases and expanded protocol coverage for SONiC so enterprise networking and security teams can shorten evaluations and improve validation for multi-vendor deployments.

Research overview

The vendor blog describes FTAS 3.1 as an incremental product update that broadens automated test coverage for SONiC-based networks. The post frames the release as intended to reduce manual validation effort and to support heterogeneous data center configurations.

Key findings

FTAS 3.1 adds explicit test suites for Quality of Service (QoS), stress scenarios and enhanced EVPN and L2VXLAN validation, and expands Simple Network Management Protocol (SNMP) and Command-Line Interface (CLI) coverage. The release also increases verification depth in resilience tests and introduces fast-reboot validation to address upgrade and reboot workflows.

Technical breakdown

The blog lists supported protocol categories and describes how FTAS exercises functionality across those layers to validate interoperability and performance. The suite is positioned to run layered tests that combine control-plane, overlay and data-plane scenarios.

Layer 2 and Layer 3

FTAS covers Ethernet and IPv4/IPv6 test cases that exercise forwarding, neighbor discovery and routing behavior. The tests include common failure modes to observe traffic recovery and routing convergence.

Overlay and EVPN

The release expands EVPN and Virtual Extensible LAN (VXLAN) coverage to validate Layer 2 and Layer 3 virtualization use cases. Tests verify tenant isolation, Monitoring-as-Code (MaC) and route advertisement behavior under normal and stressed conditions.

Control plane and management

Control-plane testing includes Border Gateway Protocol (BGP), Spanning Tree Protocol (STP), Link Aggregation Control Protocol (LACP) and MLAG scenarios, and management visibility is extended via SNMP test cases. Platform-specific CLI commands are exercised to confirm operational compatibility across vendor images.

Product update

The blog describes Continuous Integration and Continuous Deployment (CI/CD) integration points so FTAS can run as part of continuous validation pipelines to gate SONiC image and firmware changes. It also highlights day-2 testing for upgrades, configuration changes and operational troubleshooting workflows.

Operational impact

According to the post, automated test suites reduce the time required for SONiC proof-of-concept and interoperability work by producing repeatable, vendor-agnostic results. The vendor positions FTAS as a tool to surface resilience, scalability and performance issues earlier in evaluation and deployment cycles.
