When does the interval for sending HRP hello packets need to be adjusted?
Generally, the interval for sending HRP
hello packets does not need to be modified. The default interval is 1 second
and can meet most network requirements.
A short interval can speed up fault detection and switchover if the active firewall is faulty. However, when the firewall carries heavy traffic or the CPU usage on the firewall is high, detection errors and unnecessary switchovers may occur. This greatly affects services.
