The following table lists general errors and solutions in Network Configuration Manager.



To conserve per-device communication resources, Network Configuration Manager migrates active sessions between user and privilege modes. Each driver class provides the specifications of this process in the commands for Cisco driver classes. The "disable" command is used when the session is deemed to be in the privilege mode.

When the external authentication provides the account credential in the privilege mode, the usage of saved commands executes in the user mode, which requires issuing the "disable" command in terminal communications.

The Cisco common driver code checks for the existence of a privilege password. If it does not exist, the process fails to guard against locking out of the session, and returns to the privilege mode.

This scenario can be overcome by saving a privilege password for a device in the Communications tab, this can also be done for multiple devices by appropriately highlighting the devices before accessing the tab.
