Other Health Check Settings

Timeout

This setting specifies the timeout in seconds for ping/DNS lookup requests. The default

timeout is 5 seconds.

Health Check

Interval

This setting specifies the time interval in seconds between ping or DNS lookup requests.

The default health check interval is 5 seconds.

Health Check

Retries

This setting specifies the number of consecutive ping/DNS lookup timeouts after which the

Pepwave router will treat the corresponding WAN connection as down. Default health

retries is set to 3. Using the default Health Retries setting of 3, the corresponding WAN

connection will be treated as down after three consecutive timeouts.

This setting specifies the number of consecutive successful ping/DNS lookup responses

that must be received before the Pepwave router treats a previously down WAN connection

as up again. By default, Recover Retries is set to 3. Using the default setting, a WAN

connection that is treated as down will be considered as up again upon receiving three

consecutive successful ping/DNS lookup responses.
