Automatic Options - Motorola 2200 Administrator's Handbook

Administrator's Handbook
Once Backup is configured, a new field appears in the Home Page.
If your DSL WAN link fails, you can switch to your Backup Gateway by clicking the

Automatic options

If you select automatic as your Backup option, the screen expands to allow you to enter additional informa-
tion.
☛
Note:
For best results, enter an IP address and not a host name. If a host name is used it may not
be resolvable, and may keep the interface down.
•
While the Gateway is in backup mode, it will continue to ping both hosts via the primary interface. If
either host responds to a ping and the Auto Recovery checkbox is checked, the Gateway will revert to
the primary interface.
•
If you chose Auto Recovery, select Recovery Timeout (minutes1-10). Enter the number of minutes you
want the system to wait before attempting to switch back to the WAN connection. This allows you to be
sure that the WAN connection is well re-established before the gateway switches back to it from the
backup mode.
• Check the Enable Backup Gateway checkbox
134
•
Failure Timeout (minutes 1-10) – Enter the
number of minutes you want the system to wait
before the backup port becomes enabled in the
event of primary line failure. This allows you to be
sure the WAN connection is not merely briefly
interrupted before the gateway switches to
backup mode.
• Ping Host 1 and Ping Host 2 – Select address
or name from the pull-down menu enter IP
address(es) or resolvable DNS name(s) that the
Gateway will ping.
The Gateway will ping both addresses simulta-
neously at five-second intervals, recording the
ping responses from each host. The Gateway will
proceed into backup mode only if neither of the
configured remote hosts responds.
