z Portal users: Users who 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:
z Command authorization: Allows the authorization server to check each command executed by
the login user and only authorized commands can be successfully executed. For more
information about command authorization, see CLI Login in the Fundamentals Configuration
Guide.
z 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 CLI Login in the Fundamentals Configuration Guide.
z 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 the current connections. For more
information about user privilege level switching, see CLI Configuration in the Fundamentals
Configuration Guide.
You can configure different authentication, authorization, and accounting methods for different users in
a domain. For more information about the configuration, see Configuring AAA Methods for ISP
Domains .
