P-791R v2 Support Notes
WAN Backup Setup
settings
:
Backup Type:
Select the method that the P-791R v2 uses to check the DSL
connection. Select
DSL Link
to have the P-791R v2 check if the connection to
the DSLAM is up.Select
ICMP
to have the P-791R v2 periodically ping the IP
address configured in the
Check WAN IP Address
fields.
Check WAN IP Address 1-3:
Configure the field to test your P-791R v2’s
WAN accessibility. When using a WAN backup connection, the P-791R v2
periodically pings the addresses configured here and uses the other WAN
backup connection (if configured) if there is no response.
Fail Tolerance:
Type the number of times (2 recommended) that your P-791R
v2 may ping the IP addresses configured in the
Check WAN IP Address
field
without getting a response before switching to a WAN backup connection.
Recovery Interval:
When the P-791R v2 is using a lower priority connection
(usually a WAN Backup connection), it periodically checks to whether or not it
can use a higher priority connection. Type the number of seconds (30
recommended) for the P-791R v2 to wait between checks. Allow more time if
your destination IP address handles lots of traffic.
Timeout:
Type the number of seconds (3 recommended) for your P-791R v2
to wait for a ping response from one of the IP addresses in the
Check WAN IP
Address
field before timing out the request. The WAN connection is
considered “down” after the P-791R v2 times out the number of times specified
60
