2.2.11 Dynamically adding/deleting/switching physical interface

In Fast switching mode, RIP mode, Fast switching/RIP mode, and GS/SURE linkage mode (the operation mode is "c"), it is possible to add/delete bundled physical interfaces with a virtual interface kept activated (dynamic). The hanetnic command adds/deletes dynamically. See "7.9 hanetnic Command" for the detail.
Figure 2.39 shows the outline of workings when executed a command to add/delete the physical interface dynamically.
There are following two modes in a command to add/delete the physical interface dynamically.

Temporal dynamic addition/deletion:

Operates physical interfaces to bundle without editing a configuration information file. Therefore, it automatically returns to the original state by operating a machine to reboot, etc. It is not possible to add other than the physical interface that was deleted by this mode when adding dynamically.

Permanent dynamic addition/deletion:

Edits a configuration information file. Therefore, changes are reflected even after operated a machine to reboot, etc. It is not possible to delete permanently when a virtual interface is registered to the cluster resource.

In NIC switching mode, it is possible to make changes manually so that the standby physical interface can be used while the currently operating interface is active (dynamic). Figure 2.40 shows an outline of operations performed when the physical interface switching command is executed. For information on the setup,
