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 por t becomes enabled in the event of primar y line failure, ensuring that the primar y 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 par ticularly 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
primar y WAN connection. This allows you to determine how long you want the system to wait before the primar y
WAN por t becomes enabled after connectivity is restored, ensuring that the backup connection is not merely
briefly interrupted before the router switches to primar y 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 primar y 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 unncessar y and consequently no longer
suppor ted.
This command allows you to specify whether the router should tr y 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
recover y checks.) Use this setting with caution. Setting it to
yes
may induce alternating switching between
backup and recover y mode. This setting will determine the recover y 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 recover y mode to be either manually or automatically invoked.
