Example 1:
There is a nailed-up PPP interface #3, and to back it up, ISDN interface #4 is used with the default
values. Use the command:

setbackup 3 4
Example 2:
For any switched medium like ISDN there are two types of interfaces, primary and secondary
(backup). Primary interfaces automatically attempt to connect using DoD. Because of this, it is
recommended not to create any unnecessary interfaces because they will consume unnecessary
time in trying to connect. However, if additional interfaces have been created for which their need
is unknown, then DoD should be disabled. To do this, set the backup interface to itself. Do this for
each interface that should have DoD disabled. This recommendation also applies to Dial-in only
interfaces (i.e., answer mode interfaces). Use the command:

Answer mode only is set, a “dormant” state. This will set the backup interface to itself if the ISDN
interface is to be used only as a dial-in circuit (i.e., answer mode only).

Set Idle Timeouts
Set the receive and transmit idle timeouts for backup interfaces using Network Tools. This
command automatically disconnects an idle switched interface when either one of the parameters
TRANSMITIDLETIMEOUT or RECEIVEIDLETIMEOUT is met for the interface:
command automatically disconnects an idle switched interface when either one of the parameters
TRANSMITIDLETIMEOUT or RECEIVEIDLETIMEOUT is met for the interface:
setidletimeout [IFACENUM] [TRANSMITIDLETIMEOUT] [RECEIVEIDLETIMEOUT]
IFACENUM —
The number of the interface to be configured.
TRANSMITIDLETIMEOUT —
The idle time out parameter for the transmit time out.
RECEIVEIDLETIMEOUT —
The idle time out parameter for the receive time out.
Example: To set the receive time out to 180 seconds and the transmit side to 600 seconds for
ISDN interface #4, use this command:
ISDN interface #4, use this command:
setidletimeout 4 180 600
NOTE
If the interface is active, you cannot configure backup. De-activate the interface
before proceeding.
