If the switch is not needed, simply deleting it within vCenter is not enough. You must disable the hardware trigger:
using the Integrated Dell Remote Access Controller (iDRAC) . HPE ProLiant Servers using Integrated Lights-Out (iLO) . Why Does ESXi Create This Switch? vswitchbmc
If you use Dell iDRAC Service Module (iSM) or HPE iLO tools within ESXi, you should leave the switch alone. Ensure the "OS-to-iDRAC/iLO Passthrough" is correctly enabled in your server's BIOS or remote management settings to keep the link "Up" and clear the alarms. Option B: Disable the Interface If the switch is not needed, simply deleting

For those deploying , the automatic creation of vSwitchBMC can cause the "Bring-Up" process to fail because the automation tool does not expect this extra, unconfigured switch. Best Practices for Management
vSwitchBMC is not a product but a critical intersection point in virtualized infrastructure. By recognizing how virtual switches and BMCs interact—especially in shared NIC scenarios, virtual BMC implementations, and security boundaries—you can ensure both high-performance VM networking and reliable out-of-band management.
