• Portal—Portal users must pass portal authentication to access the network.
For a user who has logged in to the device, AAA provides the following services to enhance device
security:
• Command authorization—Enables the NAS to defer to the authorization server to determine
whether a command entered by a login user is permitted for the user, ensuring that login users
execute only commands they are authorized to execute. For more information about command
authorization, see the Fundamentals Configuration Guide.
• Command accounting—Allows the accounting server to record all commands executed on the
device or all authorized commands successfully executed. For more information about command
accounting, see the Fundamentals Configuration Guide.
• Level switching authentication—Allows the authentication server to authenticate users performing
privilege level switching. As long as passing level switching authentication, users can switch their
user privilege levels, without logging out and disconnecting current connections. For more
information about user privilege level switching, see the Fundamentals Configuration Guide.
You can configure different authentication, authorization, and accounting methods for different users in
a domain. See "Configuring AAA methods for ISP domains."
