3.1.1 Selecting mode

Determine which mode to use. Table 3.1 indicates the selection of modes.

For selecting adequate mode, refer to "1.1.2 Selecting mode".

[Table 3.1 Selection of modes]

Mode	Selecting mode
Fast switching mode	Select this mode if every one of the remote hosts uses Fast switching mode. This mode can detect the abnormalities of the multiplexed transfer route immediately. When abnormalities are detected, communication can be immediately changed to a normal transfer route.
NIC switching mode	Select this mode, if a hot-standby router, a network load balancer, or servers and other various network devices from other manufacturers are used. Select this mode in most cases.

It is possible to create multiple virtual interfaces in a single system to use several modes concurrently.

Specify a mode using "hanetconfig create" command with -m option.
