Configuration: Call Backup

Configure Backup
Backup is normally used to configure a backup connection if a primary connection fails. It can also
be used to reduce CPU time for an unused interface. Use the following Network Tools command to
configure backup:
setbackup [PRIMARYIFACENUM] [BACKUPIFACENUM] [TIMETOCONNECT]
[TIMETODISCONNECT] [CONNECTRETRIESNUM] [TIMEBETWEENCONNECTRETRIES]
[BACKUPOVERRIDE]
PRIMARYIFACENUM The number of the primary interface that is going to be backed up.
BACKUPIFACENUM The number of the interface assigned as the backup interface to the
primary interface.
TIMETOCONNECT How long the system will wait (in seconds) before attempting to switch
over to the backup interface. Default is zero. Allowed values are in increments of five seconds.
TIMETODISCONNECT How long the system will wait (in seconds) before attempting to
switch over to the primary interface once the primary interface has been restored. Default is 90
seconds. Allowed values are in increments of five seconds.
CONNECTRETRIESNUM Specifies the number of tries to bring up the backup interface
before giving up. The default is three. Allowed values are in increments of one.
TIMEBETWEENCONNECTRETRIES — Specifies the time interval between tries to bring up the
backup interface. The default is 30 seconds. Allowed values are in increments of five seconds.
Values below 30 seconds are allowed but not advisable.
BACKUPOVERRIDE Specifies if the backup interface will disconnect whenever the primary
interface is restored (reconnected). Choosing ENABLED for this command will not disconnect the
backup interface even though the primary interface is restored. Used specifically when the primary
interface has an intermittent problem, as it is desirable for the backup interface to stay connected
until the primary interface problem is corrected. Once the primary connection is fully operational,
BACKUPOVERRIDE should be set to DISABLED, the default value.
NOTE
The commands in the rest of the procedure are Network Tools commands. Refer to
the host platform manual for detailed information on accessing Network Tools.
