Backup IP Gateway Settings
The purpose of Backup is to provide a recover y mechanism in the event that the primar y connection fails. 
Should the primar y WAN connection fail, traffic would be automatically redirected through your alternate 
gateway device to maintain Internet connectivity. See 
 for more information.
set backup option [ disabled | manual | automatic ]
Specifies whether backup to an IP gateway is 
disabled or enabled as manual or automatic. Default is dis-
abled.
set backup failure-timeout [ 1 - 10 ]
Specifies the number of minutes you want the system to wait before the backup por t becomes enabled in 
the event of primar y line failure, when 
backup option is set to automatic. Sets the Default is 1.
set backup ping-host [ 1 | 2 ] [ name | address ]
Specifies whether the Gateway will ping an IP address or resolvable DNS name, when 
backup option is set 
to 
automatic. These are optional items that are particularly useful for testing if the remote end of a VPN 
connection has gone down.
The Gateway will ping both addresses simultaneously at five-second inter vals, recording the ping responses 
from each host. The Gateway will proceed into backup mode only if neither of the configured remote hosts 
responds.
set backup ping-host [ 1 | 2 ] [ name 
hostname | ip-address ip_address ]
Specifies an IP address or resolvable DNS name for the Gateway to ping.
set backup auto-recovery [ off | on ]
Turns automatic recover y 
off or on. Default is off.
set backup recovery-timeout [ 1 - 10 ]
If 
auto-recovery is set to on, specifies the number of minutes for 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-estab-
lished before the gateway switches back to it from the backup mode. Default is 
1.
set ip backup-gateway option [ on | off ]
Turns the backup gateway option 
on or off. Default is off.
set ip backup-gateway interface ip-address
