Figure 22 WAN Backup

The following table describes the labels in this screen.

Table 13 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 either traffic redirect or dial backup, 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.
