02 - Enable Mode Passwords (Optional)
These credentials are stored in Settings → Authentication. Privileged credentials are generally only necessary for configuration management. However, some platforms require privileged credentials to access basic network state information, such as MST spanning-tree state or 802.1X session information.
If enable mode is configured with no password and is needed for discovery, any enabled password information needs to be set! Otherwise, IP Fabric won’t even try the enable command.
Please be careful to configure enable password only for devices (subnets) that need the enable command to be included. We encountered some problems with Cisco ISE. When an incorrect enable password was entered, the user account was locked and IP Fabric wasn't able to finish the discovery for those devices.
