SYSTEM BACKUP SUCCESSRATE
Changes the minimum success rate required for a group of pinged addresses. If the success rate is less than the
minimum, the DSL link is assumed to have failed and a switchover to the backup is performed.
Note: If you change the success rate to 0, you disable pinging for that group of addresses.
Note: A minimum success rate of 100% is not recommended; this would require a reply from every ping sent.
To see the current success rate values, use the system list command. For more information about success rates and
Dial Backup, see Ping Interval, Number of Samples, and Success Rate, on page 105.
