New Features

Scalability and Performance

Support for Large Install Base - OmniVista Network Advisor can support a maximum of 2,000 devices, enabling real-time monitoring of network devices in large organizations.

Notification Management

Configurable Anomaly Notification Delay - If the same anomaly is detected on the same IP address, a notification is not sent to Rainbow immediately. Notifications are only repeated after 10 minutes. This default delay can be configured in minutes, with a minimum of 1 minute, allowing you to set the alert frequency on Rainbow according to your needs.

Enhanced Network Security

Support for Protected IPs and Subnets - OmniVista Network Advisor can now support protected IPs and subnets within your network range.

Improved Anomaly Management

Color-Coded Anomaly Labels - OmniVista Network Advisor now features color-coded labels, allowing you to easily see the category of each anomaly at a glance.

Auto-Remediation Tracking

"Remember My Decision" Click Tracking - You can now determine if someone has clicked on "remember my decision" in the bubble, allowing you to know immediately when auto-remediation has been activated for a device.

User Notification

Configurable Notifications - With OmniVista Network Advisor, you can configure notification hours based on Rainbow bubbles. Once a bubble is set up, you can assign different notification to any users within the bubble.

Device Organization

Grouping Devices - OmniVista Network Advisor allows users to add custom tags to any device. These tags can include information such as location, floor, building, or the model name of the switch or access point, for example.

Configuration Management

Persistent Switch Configuration - Previously, changes made to a switch were only stored in memory, and would be lost if the switch rebooted. The new OmniVista Network Advisor feature now allows you to save the switch configuration after making changes, ensuring they persist even after a reboot.

Security Compliance and Maintenance

• GDPR/CCPA Report

• Improve serviceability.

• Updated FOSS Report

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.
