In GS 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. In addition, ping monitoring is performed at regular intervals for the path where an error was detected. If the path recovery is detected or is notified by the remote system, the recovered path will be re-enabled after a message is sent out.
Note
If no response after the ping command run for 30 seconds, the hang-up will be detected.
