3Com Router 3000 Ethernet Family
Configuration Guide
Login users are also classified into four levels that correspond to the four command
levels. After users at different levels log in, they can only use commands at their own
level or lower levels.
To fence off intrusion of illegitimate users, legitimate users are required to provide the
correct super password, if one has been configured using the super password
command, when they switch from a lower level to a higher level. For privacy, the
entered password is not displayed on the screen. Users have three chances to provide
the correct password. Only after the correct password is entered can they switch to the
higher level. Otherwise, the original user level remains unchanged.
The command views are implemented according to configuration requirements which
are related to one other. For example, after logging onto the router you enter user view
where you can only view state and statistic information. In user view, key in
system-view to enter system view where you can key in different configuration
commands to enter their views.
Command lines are associated with the views described in the following table.
