Monitoring AAA Accounting
Dell Networking OS does not support periodic interim accounting because the periodic command can
cause heavy congestion when many users are logged in to the network.
No specific show command exists for TACACS+ accounting.
To obtain accounting records displaying information about users currently logged in, use the following
command.
• Step through all active sessions and print all the accounting records for the actively accounted
functions.

Suppressing AAA Accounting for Null Username Sessions
When you activate AAA accounting, the Dell Networking OS software issues accounting records for all
users on the system, including users whose username string is NULL because of protocol translation.
An example of this is a user who comes in on a line where the AAA authentication login method-list
none command is applied. To prevent accounting records from being generated for sessions that do not
have usernames associated with them, use the following command.
• Prevent accounting records from being generated for users whose username string is NULL.

aaa accounting suppress null-username
Enabling SCP and SSH
Secure shell (SSH) is a protocol for secure remote login and other secure network services over an
insecure network. Dell Networking OS is compatible with SSH versions 1.5 and 2, in both the client and
server modes. SSH sessions are encrypted and use authentication. SSH is enabled by default.
For details about the command syntax, refer to the Security chapter in the Dell Networking OS Command
Line Interface Reference Guide.
Dell Networking OS SCP, which is a remote file copy program that works with SSH.
NOTE: The Windows-based WinSCP client software is not supported for secure copying between a
PC and a Dell Networking OS-based system. Unix-based SCP client software is supported.
