Command Authorization Configuration Example
Network diagram
As shown in Figure 4-2 , command levels should be configured for different users to secure Device: After
a user logs in to Device, the commands the user enter must be authorized by the HWTACACS server
first before being executed. If the HWTACACS server fails to authorize the commands, local
authorization is used.
