Table 17 WAN Backup
LABEL DESCRIPTION
Backup Type Select the method that the Prestige uses to check the DSL connection.
Select
DSL Link to have the Prestige check if the connection to the DSLAM is up.
Select ICMP to have the Prestige periodically ping the IP addresses configured in
the Check WAN IP Address fields.
Check WAN IP
Address1-3
Configure this field to test your Prestige's WAN accessibility. Type the IP address of
a reliable nearby computer (for example, your ISP's DNS server address).
Note: If you activate traffic redirect, you must configure at least one
IP address here.
When using a WAN backup connection, the Prestige 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 Prestige may ping the IP
addresses configured in the Check WAN IP Address field without getting a
response before switching to a WAN backup connection (or a different WAN
backup connection).
Recovery Interval When the Prestige 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 Prestige to wait between
checks. Allow more time if your destination IP address handles lots of traffic.
