New Features

Data Collection and Analysis Using APIs from Third-Party Devices

OmniVista Network Advisor now has the capability to connect to third-party network devices and collect syslog data. The collected syslogs can be analyzed using custom anomalies designed to process this data. With the necessary device connection and command execution permissions, custom remediation actions for these anomalies can be executed on the third-party device.

License Support for Third-Party Devices

A new license part number must be created and assigned to third-party devices to enable their integration and management within the system as implemented. This allows for proper tracking, support, and utilization of the third-party devices under the OmniVista Network Advisor platform.

Custom Anomaly and Remediation Creation

OmniVista Network Advisor now allows the creation of custom anomalies and their corresponding remediations. By setting up a custom anomaly, you can define and manage its remediations directly on the “Custom Anomaly” page.

Rollback of Remediations via Rainbow

OmniVista Network Advisor now provides the ability to roll back remediations directly through Rainbow. Previously, when an anomaly was detected, a remediation was suggested through an adaptive card in Rainbow. If the remediation was applied by mistake or if the user wanted to roll it back, they had to manually access OVNA, find the anomaly, and perform the rollback. This new feature streamlines the process, allowing users to revert changes quickly and efficiently.

Support for OVNA Installation on Official RedHat Enterprise Version

OmniVista Network Advisor now supports installation on the official RedHat Enterprise Linux (RHEL) version. This ensures compatibility with RHEL, enabling organizations to deploy OVNA seamlessly on RedHat's robust, enterprise-grade operating system for enhanced reliability, security, and performance in managing network devices.

OmniVista Network Advisor Now Available in French

The OmniVista Network Advisor solution is now offered in the French language, providing a localized experience for French-speaking users. This update enhances accessibility and usability, allowing users to navigate and manage network features in their preferred language.

Microsoft Teams Integration in OmniVista Network Advisor

To expand OVNA's strategy beyond Rainbow, OmniVista Network Advisor now officially supports Microsoft Teams. This integration allows users to utilize Microsoft Teams as a collaborative tool within the Network Advisor solution, enhancing flexibility and collaboration options.

Known Issues and Workarounds

• Internet access is mandatory for the installation setup and for proper functioning.

• After any OmniSwitch devices reboot if no ‘write memory’ has been done the following two commands must be run so the devices are still monitored by OmniVista Network Advisor:

-> swlog output socket <IP address> <port>
-> appmgr restart ams cron-app

The above command is valid for OS6xxx and OS9xxx only.

• Network Loop anomaly is only supported on OmniSwitch models OS6860(E), OS6860N, OS6900.

• OS6860 and OS6860N Core dumps are generated until the ‘pmd’ directory is full. Fixed in AOS 8.9R01 GA.

·        AOS switches: When setting the TLS method in syslog, the correct outgoing interface is not correctly set with the command ip service source-ip <interface-2> all if <interface-1> is changed by <interface-2>. Fix is planned with 8.9R04 GA.

• Stellar APs running in Express mode support remote syslog server port 514 only.

• Incorrect NTP settings may prevent a device from being properly monitored by OmniVista Network Advisor.

• Some anomalies do not work if the switch is configured in aaa JITC or aaa enhanced mode.

• Activation of DEBUG log on the OmniSwitch can result in a high impact on OmniVista Network Advisor storage.

• Backup files must be deleted manually by OmniVista Network Advisor operator on the host instance.

• When using a proxy during the installation of OmniVista Network Advisor, the "Check Connection" button may fail. However, after setup, all other Rainbow operations (e.g., notifications, remediation) function normally, and OmniVista Network Advisor operates as expected.
