New Enterprise-class Features

AOS 2.2 includes new capabilities, making the solution an ideal fit for some of the most demanding environments. New features include:

  • TACACS+ support and customizable RBAC roles — allows businesses to tune user permissions at a granular level to create user profiles that matches specific boundaries and policies.
  • Audit trail — for customers to monitor login access to AOS and audit each change for better troubleshooting and compliance.
  • Extensible IBA probes via AOS GUI, custom collectors — for day 2 operations.
Enterprise-class Features

AOS 2.2 provides the ability to pull directly from the AOS GUI, to manually configure the AOS analytics pipeline or instantiate one of the pre-defined IBA probes to set up proactive closed-loop monitoring and actionable alerts, as well as detect gray failures and other anomalies. Key updates include:
