Security
This chapter describes several ways to provide security to the Dell Networking system.
For details about all the commands described in this chapter, refer to the
Security chapter in the Dell Networking OS Command
Reference Guide .
AAA Accounting
Accounting, authentication, and authorization (AAA) accounting is part of the AAA security model.
For details about commands related to AAA security, refer to the Security chapter in the Dell Networking OS Command Reference
Guide .
AAA accounting enables tracking of services that users are accessing and the amount of network resources being consumed by
those services. When you enable AAA accounting, the network server reports user activity to the security server in the form of
accounting records. Each accounting record comprises accounting attribute/value (AV) pairs and is stored on the access control
server.
As with authentication and authorization, you must configure AAA accounting by defining a named list of accounting methods and
then applying that list to various virtual terminal line (VTY) lines.

The following sections present the AAA accounting configuration tasks.
• Enabling AAA Accounting (mandatory)
• Suppressing AAA Accounting for Null Username Sessions (optional)
• Configuring Accounting of EXEC and Privilege-Level Command Usage (optional)
• Configuring AAA Accounting for Terminal Lines (optional)
