Re-installing a SBC system from an ".iso" image followed by restoring SBC configuration from a tar.gz backup file may lead to loss of encrypted configuration parameters in the following scenarios:

  • re-installing a standalone SBC from an ".iso" image followed by restoring SBC configuration from a "tar.gz" backup file
  • re-installing both nodes in an HA SBC pair from an ".iso" image followed by restoring SBC configuration from a "tar.gz" backup file

Activities like replacing a single node in an HA pair (as an RMA for example) or re-installing a single node in an HA pair at a time are safe. The node that has just been re-installed will take the current configuration from the active node.

    titleExample
    admin@SBC01a> show table system savedConfigList

Info

You must follow the procedure below to activate the traffic profile during loadconfig scenarios. Loadconfig does not activate the profile

To configure the required profiles you must first reset the profile to default, and then set desired profile.

1. Note the current active profile from CLI (xxx_profile).
2. After loadconfig is done, activate the default profile in the system because the system will be in default profile.
3. After the system comes up after a reboot, activate the old active profile (for example, xxx_profile).

 

 

Warning
This command will restart application on both the servers and is service impacting.

titleNote

When reloading a saved configuration, make sure the standby server is stable or the server is reachable. If the standby is restarted or rebooted, wait until the server is stable before proceeding.

If the standby system crashes before the load config completes, stop the standby server and allow the original active server to come back online as active.
