In GS/SURE linkage mode, the ping command is issued against the IP address of the actual interface of the remote system at regular interval.
In any one of the following cases, the route is switched and a reporting message will be output:
A transfer path failure is detected.
A hang-up of the ping command is detected.
A failure notification is received from the remote system.
Then, communication is continued using other transfer path.
This function is used exclusively for GS/SURE linkage mode. In Fast switching mode, when the virtual interface activates, the process will be executed automatically. RIP mode or NIC switching mode are not capable of using this function.
Note
If no response after the ping command run for 30 seconds, the hang-up will be detected. However, it can only be detected when the patch 914233-10 or later is applied in Solaris 10 environment.
