no useful running ifconfig vmnic1 down

I see no "UP" in the output of "ifconfig vmnic1 " after running "ifconfig vmnic1 down" . However , from vmware side , vmnic1 is not "down" via "./esxcfg-nics -l ". it's useful to disable/enable these nic ports during networking troubleshooting . which way can I disable vmnic ?

What's the output of?

ethtool vmnic1

Is your NIC controller in HCL? And is enable also in BIOS?

which way can I disable vmnic ?

I'm not sure that there is a command to disable a single nic.

In this case I simple remove the nic from the vSwitch.

Move the adapter from active to unused in the NIC teaming properties of the vSwitch. That way the vmnic is not used by the vSwitch anymore.

Alternatively you could remove the vmnic from the vSwitch.

There is no way?

your standard linux ifconfig in the service console is not going to do anything to a vmnic as thats under the control of the vmkernel. If there is anything is will be in the esxcfg commands (or other vmware specific commands).

vmware services take over almost all network control so that it's no use stopping network service neither . The only way , as far af i know for 3.5 ,is to shutdown the Vm esx host .
