ADDC controller (CTL), three nodes red on 8443 page
Problem Description
ADDC controller (CTL), three nodes on page 8443 are highlighted in red, indicating multiple anomalies
Process Analysis
Troubleshooting revealed that three nodes were pinging each other. Node 1 experienced packet loss when pinging node 2 and node 3, while no packet loss occurred between node 2 and node 3. The configuration files for the controller member NICs and bond0 NICs were checked and found to be correct. Upon inspecting the switch ports connected to the controller, the aggregation port was up but configured as static aggregation. The controller NIC bonding requires the peer switch to use dynamic aggregation.
Solution
Change switch aggregation port to dynamic aggregation
