If you are running your ESX or ESXi management console on DHCP and need to force a DHCP lease renewal, here is how it can be done in both ESX and ESXi.

ESX:  Run the following two commands locally in the service console (COS):

ifdown vswif0
ifup vswif0

ESXi:  Use the local console menu to “Restart Management Network”:

    If you can run ‘screen’ at the console you might be able to get away with:

    ifdown vswif0 ; ifup vswif0

    ‘nohup’ (if available) can do that as well, but it is a pain to use.
