Use the following command syntax to set options for a virtual network device that already exists.
# ldm set-vnet [mac-addr=num] [vswitch=vswitch-name] [mode=[hybrid]] [pvid=[port-vlan-id]] [linkprop=[phys-state]] [vid=[vlan-id1,vlan-id2,...]] [mtu=[size]] if-name ldom
mode= (left blank) disables NIU Hybrid I/O.
if-name, interface name, is the unique name assigned to the virtual network device you want to set.
ldom specifies the logical domain from which to remove the virtual network device.
Otherwise, the command arguments are the same as described in Add a Virtual Network Device.
