ASDM does not support assigning IPv6 addresses to the interfaces.

To create a sub-interface, click Add under Configuration > Features > Interfaces and select the physical interface from the Hardware Port drop-down menu. Specify the interface name, VLAN ID, sub-interface ID, security level, and an IP address to complete the sub-interface setup, as shown in Figure 18-14. A new sub-interface is being created on the GigabitEthernet0/3 physical interface with a sub-interface and VLAN ID of 200. The interface name is Web and a security level of 20 is assigned to it. The IP address is being assigned from a DHCP server.
