Chapter 10 Interface
Like other interfaces, virtual interfaces have an IP address, subnet mask, and gateway used to
make routing decisions. However, you have to manually specify the IP address and subnet
mask; virtual interfaces cannot be DHCP clients. Like other interfaces, you can restrict
bandwidth through virtual interfaces, but you cannot change the MTU. The virtual interface
uses the same MTU that the underlying interface uses. Unlike other interfaces, virtual
interfaces do not provide DHCP services, and they do not verify that the gateway is available.
This screen lets you configure IP address assignment and interface parameters for virtual
interfaces. To access this screen, click an Add icon next to an Ethernet interface, VLAN
interface, or bridge interface in the respective interface summary screen. The fields vary by
interface.
