After the configuration is complete, when users Telnet to the device, they must enter the password 12345678. After passing authentication, they can use commands of levels 0, 1, and 2.
Switching the user privilege level
Users can switch to a different user privilege level without logging out and terminating the current connection. After the privilege level switching, users can continue to manage the device without relogging in, but the commands they can execute have changed. For example, with the user privilege level 3, a user can configure system parameters. After switching to user privilege level 0, the user can execute only basic commands like ping and tracert and use a few display commands. The switching operation is effective for the current login. After the user relogs in, the user privilege restores to the original level.
To avoid problems, HP recommends that administrators log in with a lower privilege level to view switch operating parameters, and switch to a higher level temporarily only when they must maintain the device.
When administrators must leave for a while or ask someone else to manage the device temporarily, they can switch to a lower privilege level before they leave to restrict the operation by others.
