Netopia 3300 - Manual (Page 242)

8-10 Firmware User Guide
This screen is used to configure the conditions under which backup will occur, if it will recover, and how the
modem is configured.
For the internal V.92 modem, the Backup Configuration screen appears as follows, when all options are enabled
(default screen shows fewer menu items until some are enabled):
• Select Backup is and from the pop-up menu, select Automatic (default), Manual, or Disabled. You enable
line backup by selecting either Manual or Automatic. For fail-over purposes, choose Automatic.
• Select Requires Failure of (minutes) and enter the number of minutes that the system should wait before
it assumes that a connection failure has occurred. After that period, the system would switch to backup
mode and connect via the modem.
Note: Backup and Recover y have resolutions of five seconds. This is how often the router evaluates the state
of the connections and makes decisions.
• Select Ping Host Name or IP Address #1 and #2 and enter IP address(es) or resolvable DNS name(s) that
the Router will ping. These are optional items that are par ticularly useful for testing if the remote end of a
VPN connection has gone down.
The Router will ping both addresses simultaneously at five-second inter vals, recording the ping responses
from each host. The Router will proceed into backup mode only if neither of the configured remote hosts
responds.
While the Router is in backup mode, it will continue to ping both hosts via the primar y inter face. If either
host responds to a ping and Recovery is set to Automatic, the Router will rever t to the primar y inter face.
