n
Ping test
: Tests connectivity by sending an ICMP echo request to the hostname or IP
address specified in
Ping host
. You can also optionally change the number of bytes in
the
Ping payload size
.
n
DNS test
: Tests connectivity by sending a DNS query to the specified
DNS server
.
n
HTTP test
: Tests connectivity by sending an HTTP or HTTPS GET request to the URL
specified in
Web servers
. The URL should take the format of
http[s]://
hostname
/
[
path
]
.
n
Test DNS servers configured for this interface
: Tests connectivity by sending a DNS
query to the DNS servers configured for this interface.
n
Test the interface status
: The interface is considered to be down based on:
l
Down time
: The amount of time that the interface can be down before this test is
considered to have failed.
Allowed values are any number of weeks, days, hours, minutes, or seconds, and
take the format
number
{
w|d|h|m|s
}.
For example, to set
Down time
to ten minutes, enter
10m
or
600s
.
The default is 60 seconds.
l
Initial connection time
: The amount of time to wait for an initial connection to the
interface before this test is considered to have failed.
Allowed values are any number of weeks, days, hours, minutes, or seconds, and
take the format
number
{
w|d|h|m|s
}.
For example, to set
Initial connection time
to ten minutes, enter
10m
or
600s
.
The default is 60 seconds.
12. Optional active recovery configuration parameters:
a. Change the
Interval
between connectivity tests.
Allowed values are any number of weeks, days, hours, minutes, or seconds, and take the
format
number
{
w|d|h|m|s
}.
For example, to set
Interval
to ten minutes, enter
10m
or
600s
.
The default is 15 minutes.
b. If more than one test target is configured, for
Success condition
, determine whether the
interface should fail over based on the failure of one of the test targets, or all of the test
targets.
c. For
Pass threshold
, type or select the number of times that the test must pass after
failure, before the interface is determined to be working and is reinstated.
d. For
Failed attempts
, type the number of probe attempts before the WAN is considered to
have failed.
e. For
Response timeout
, type the amount of time that the device should wait for a response
to a probe attempt before considering it to have failed.
Allowed values are any number of weeks, days, hours, minutes, or seconds, and take the
format
number
{
w|d|h|m|s
}.
For example, to set
Response timeout
to ten minutes, enter
10m
or
600s
.
The default is 15 seconds.
13. (Optional) Repeat this procedure for IPv6.
