Issue/Introduction

  • In vCenter, operations to modify portgroups, add/remove pNics, or modify Teaming policies on a vSS or vDS fail with the error: 
     "A specified parameter was not correct"
  • Unable to modify or add a gateway of a TCP/IP Stack.
  • "Invalid NIC" errors are seen in hostd.log:

The vusb0 device may appear on two vSwitches when running the command esxcfg-vswitch -l:

Environment

VMware vSphere ESXi 
VMware vSphere vCenter

Cause

If NetworkSystem.invokeHostTransactionCall is called to make changes to a vSS or vDS while there is a configuration issue with vSwitchUSB0, the change operation will fail.  In this particular case, vusb0 did not exist on bootup.
 
syslog.log: 
YYYY-MM-DDTHH:MM:SS.548Z jumpstart[2097601]: VirtualSwitch: Unable to restore uplink vusb0  of virtual swtich vSwitchUSB0. Reason was Unable to find mapping for vusb0:

YYYY-MM-DDTHH:MM:SS.549Z jumpstart[2097601]: PortGroup: NIC vusb0 does not exist

Resolution

To resolve, one of the following steps can be taken:

  • Re-add the vusb0 to vSwitchUSB0: 
    esxcli network vswitch standard uplink add --uplink-name="vusb0" --vswitch-name="vSwitchUSB0" 
  • Toggle the vSwitchUSB0/vusb0 Teaming policy from Active to Standby or Unused (or vice versa). 
  • Remove vSwitchUSB0.  If it repopulates, contact your hardware vendor on how to properly disable the vUSB device.
    esxcli network vswitch standard remove --vswitch-name=vSwitchUSB0

 

To ensure persistent disablement across reboots:

  • Use the following command to prevent the creation of a virtual switch vSwitchUSB0 and associated portgroups on the next reboot of host.
[root@esx:~] esxcfg-advcfg -s 0 /Net/BMCNetworkEnable

The value of BMCNetworkEnable is 0 and the service is disabled. It can be validated using following command:

[root@esx:~] esxcfg-advcfg -g /Net/BMCNetworkEnable

Output 'Value of BMCNetworkEnable is 0' means disabled.
