It is possible to define several IP addresses (logical virtual interfaces) on a single virtual interface. Using this function, various IP addresses can be used for each application.
Figure 2.28 Logical virtual interfaces being defined shows an example of defining three IP addresses (logical virtual interface) on a single virtual interface sha0.
Figure 2.28 Logical virtual interfaces being defined
In the above figure, sha0:2 to sha0:4 are called logical virtual interfaces in this document. For each logical virtual interface, please assign the address in the same subnet as the virtual interface where the logical virtual interface belongs. For operation on a cluster system, please assign the address in the same subnet as the takeover address.
Note
This function is only available for Fast switching mode, and RIP mode. The other mode such as GS/SURE linkage mode does not apply.
For NIC switching mode, if using physical interface sharing function, it can process (a process of allocating multiple IP addresses to one physical interface) equally as this function.
