When a switch disconnects from the Nebula Control Center (NCC) after changing the management VLAN, several factors may contribute to the issue. Here are the potential reasons and troubleshooting steps:
VLAN Tagging:
- Ensure that the switch ports connecting to the Nebula Control Center and other relevant network devices are correctly configured for VLAN tagging, especially if the new management VLAN requires tagging.
Please check the switch uplink port has set the correct PVID or has tagged out with the corresponding VLAN.
