The URL will be retrieved when performing an HTTP health check. When String
to Match is left blank, a health check will pass if the HTTP return code is between
200 and 299 (Note: HTTP redirection codes 301 or 302 are treated as failures).
When String to Match is filled, a health check will pass if the HTTP return code is
between 200 and 299 and if the HTTP response content contains the string.
WAN Settings>WAN Edit>Health Check Settings>URL2
If URL2 is also provided, a health check will pass if either one of the tests passed.
Other Health Check Settings
This setting specifies the timeout in seconds for ping/DNS lookup requests. The
default timeout is 5 seconds .
This setting specifies the time interval in seconds between ping or DNS lookup
requests. The default health check interval is 5 seconds .
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.
Automatic Public DNS Server Check on DNS Test Failure
When the health check method is set to DNS Lookup and health checks fail, the Pepwave router will
automatically perform DNS lookups on public DNS servers. If the tests are successful, the WAN may not
be down, but rather the target DNS server malfunctioned. You will see the following warning message on
the main page:
