Virtual interfaces are automatically inactivated at system shutdown. To inactivate virtual interfaces without a system restart, use the stphanet command.
For details about this command, see Section "7.3 stphanet Command".
Note
Be sure to use a stphanet command to deactivate a virtual interface. Do not use an ifconfig command to do the operation.
If the Solaris zone is using the virtual interface, you cannot deactivate it. First, stop the Solaris zone then deactivate the virtual interface.
