https://community.ui.com/releases/UniFi-OS-Dream-Machines-4-0-6/bac12326-92be-490e-b5da-9ab55195a903
Overview
UniFi OS 4.0.6 adds support for Automatic Failover for Shadow Mode, SNMP, and includes the improvements and bugfixes listed below.
Automatic Failover for Shadow Mode
With Automatic Failover, a secondary Shadow Gateway mirrors the Primary Gateway in order to provide High Availability (HA).
- Both gateways are interconnected using a dedicated high availability link and the configuration and WAN/LAN cabling is mirrored.
- The network connection information is synchronized between the gateways, allowing for immediate failover.
- In the event of a hardware failure, the shadow automatically takes over with minimal downtime.
- Set up Automatic Failover from the UniFi OS Applications page. See the Shadow Mode Help Center article for more information.
Bundled application
- UniFi Network 8.2.93
