Determine which mode to use. Table 3.1 Selection of modes indicates the selection of modes.
For selecting adequate mode, refer to "1.1.2 Criteria for selecting redundant line control methods".
Mode | Selecting mode |
|---|---|
Fast switching mode | Select this mode if every one of the remote hosts is a Solaris server or Linux server. 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. |
RIP mode | Select this mode if communicating with server over the other network and attempting to switch over using RIP standard protocol. Usually, this mode is not used |
Fast switching/ RIP mode | Select this mode if using a single virtual interface in Fast switching mode and RIP mode at the same time. |
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. |
GS/SURE linkage mode | Select this mode if using GS and SURE SYSTEM exclusively. Other servers or any network device must not exist in the same network. |
It is possible to create multiple virtual interfaces in a single system to use several modes concurrently, though it is not possible to use RIP mode and GS/SURE linkage mode together.
Note
In order to use redundant mode on a single system, you must provide NIC for each mode. For example, when using hme0 and hme1 in Fast switching mode, the other modes such as NIC switching or GS/SURE linkage mode must use different NIC (such as hme2 and hme3).
Specify a mode using "hanetconfig create" command with -m option.
