Issue/Introduction
Starting with vSphere 8.0, in both Integrated Dell Remote Access Controller (iDRAC) and HP Integrated Lights Out (ILO), when you have a USB interface enabled, vUSB or vNIC respectively, an additional standard switch vSwitchBMC with uplink vusb0 gets created on the ESXi host.
When deleting this vSwitch, it is automatically recreated
Environment
VMware vSphere ESXi 8.0
Cause
This is expected behavior.
Starting with vSphere 8.0, in both Integrated Dell Remote Access Controller (iDRAC) and HP Integrated Lights Out (ILO), when you have a USB interface enabled, vUSB or vNIC respectively, an additional standard switch vSwitchBMC with uplink vusb0 gets automatically created on the ESXi host.
Resolution
After vSphere 8.0 installation, use the ESXCLI command esxcfg-advcfg -s 0 /Net/BMCNetworkEnable to prevent the creation of a virtual switch vSwitchBMC and associated portgroups on the next reboot of host.
See this script as an example:
~# esxcfg-advcfg -s 0 /Net/BMCNetworkEnable
The value of BMCNetworkEnable is 0 and the service is disabled.
~# reboot
On host reboot, no virtual switch, PortGroup and VMKNIC are created in the host related to remote management application network.
