If you need to test the network connectivity of a leased line, enter an IP address
in the CIDR block from which workloads are routed to the private network through the

Note If you need to test the connectivity to different destination IP addresses, specify
a unique source IP address for each destination IP address. Make sure that the source
and destination IP addresses are accessible from both directions.
|
Detection Interval |
Enter the health check interval. The next health check does not start only after the
current one is complete. Valid values: 1000 to 60000. Default value: 2000. Unit: milliseconds.
Note The interval must be longer than the timeout period of health checks.

Valid values: 1 to 15. Default value: 3.
|
Maximum RTT Allowed |
Enter the maximum round-trip time (RTT) allowed. Value values: -1 and 1 to 5000. Default
