Configuring RADIUS Accounting
3. (Optional) Configure Session Blocking and Interim
Updating Options
These optional parameters give you additional control over accounting data.
■ Updates: In addition to using a Start-Stop or Stop-Only trigger, you
can optionally configure the switch to send periodic accounting
record updates to a RADIUS server.
■ Suppress: The switch can suppress accounting for an unknown user
having no username.
Syntax: [no] aaa accounting update periodic < 1 - 525600 >
Sets the accounting update period for all accounting ses-
sions on the switch. (The no form disables the update
function and resets the value to zero.) (Default: zero; dis-
abled)
Syntax: [no] aaa accounting suppress null-username
Disables accounting for unknown users having no user-
name. (Default: suppression disabled)
To continue the example in figure 5-8, suppose that you wanted the switch to:
■ Send updates every 10 minutes on in-progress accounting sessions.
■ Block accounting for unknown users (no username).
• Update Period
• Suppress Unknown User
