Suppressing Generation of Accounting Records for Null Username Sessions

When AAA Accounting is activated, the Cisco IOS software issues accounting records for all users on the
system, including users whose username string, because of protocol translation, is NULL. An example of this
is users who come in on lines 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 in global configuration mode:
Command
Device(config)#
null-username
Purpose
Note
Enables the generation of system accounting records for private
server hosts when they are added or deleted.
Exits server-group configuration mode and returns to privileged
EXEC mode.

• (Optional) 0 with the server-keyargument specifies that an
unencrypted (cleartext) hidden server key follows.
• (Optional) 7 with the server-key argument specifies that an
encrypted hidden server key follows.

the server-keyargument is configured without the 0 or 7
preceding it, it is unencrypted.

system accounting is enabled.

for users whose username string is NULL.
