Setting Command Levels

Setting Command Levels

The system divides commands into four levels and sets the command level in the specified view. The device administrator can change the command level as required, so that a lower-level user can use some high-level commands. The device administrator can also change the command level to a larger value to improve device security.

Context

  • The system grants users different access permissions based on their roles. User levels are classified into sixteen levels, which correspond to the command levels. Users can use only the commands at the same or lower level than their own levels. By default, there are four command levels 0 to 3 and sixteen user levels 0 to 15. Table 1-1 describes the relationship between command levels and user levels.
