2-116 Command Line Interface Commands Reference
backup delay 1..65535
This command allows you to set the number of seconds before the router invokes the dial backup feature in the
event of loss of connectivity. This allows you to determine how long you want the system to wait before the
backup port becomes enabled in the event of primary line failure, ensuring that the primary WAN connection is
not merely briefly interrupted before the router switches to backup mode. Minimum is 10 seconds.
backup [no]
This command allows you directly to invoke or cancel the backup mode.
backup ping host { ip-address | host-name }
This command allows you to enter an IP address or resolvable DNS name that the router will ping. This is an
optional item that is particularly useful for testing if the remote end of a VPN connection has gone down. Should
this address become unreachable the router will treat this as a loss of connectivity and begin the backup timer.
This loss is a Layer 2 loss.
backup recovery delay 1..65535
This command allows you to set the number of seconds before the router attempts to recover back to the
primary WAN connection. This allows you to determine how long you want the system to wait before the primary
WAN port becomes enabled after connectivity is restored, ensuring that the backup connection is not merely
briefly interrupted before the router switches to primary mode. Minimum is 10 seconds.
backup recovery idle delay 1..65535
This command allows you to set the number of seconds for the backup link to be idle, i.e. passing no traffic,
before the router attempts to recover back to the primary WAN connection.
backup recovery idle only { yes | no }
This command allows you to toggle the idle delay on or off.
backup recovery layer-2-loss { yes | no }
Note: Beginning with Firmware Version 8.3.3, this command is unncessary and consequently no longer
supported.
This command allows you to specify whether the router should try to auto-recover when the backup is invoked
because of a layer 2 loss, for example, no valid Connection Profile. (Layer 1 is still available, and this is what
recovery checks.) Use this setting with caution. Setting it to yes may induce alternating switching between
backup and recovery mode. This setting will determine the recovery behavior of a manual backup and ping
failure backup. These two failures are treated as layer 2 failures.
backup recovery mode { manual | automatic }
This command allows you to specify the backup recovery mode to be either manually or automatically invoked.
