A specified parameter was not correct. Vim.Host.VirtualSwitch.LinkDiscoveryProtocolConfig

I’m getting this error when I wanted to remove a vmnic from a virtual switch

After some debuging and a search on google I discoverd the there was a option missing in the /etc/vmware/esx.conf file. How come? This server was upgraded from a ESX 3 to vSphere 4.

So how can I get ride of this error? Simple just give the following command:

esxcfg-vswitch -B both vSwitch0

Make sure you replace vSwitch0 with the name of your virtual switch! There is no need to reboot the server.

Also make sure you refresh the view in the vSphere client before make new changes to the network config.
