Setting User Usage Quotas Options
You can define usage quotas for individual users. You can limit users in one or
both of two ways:
both of two ways:
•
By total duration of sessions for the period selected
•
By the total number of sessions for the period selected
For Cisco Secure ACS purposes, a session is considered any type of user
connection supported by RADIUS or TACACS+, for example PPP, or Telnet, or
ARAP. Note, however, that accounting must be enabled on the AAA client for
Cisco Secure ACS to be aware of a session. If you make no selections in the
Session Quotas section for an individual user, Cisco Secure ACS applies the
session quotas of the group to which the user is assigned.

Tip
The Current Usage table under the User Usage Quotas table on the User Setup
Edit page displays usage statistics for the current user. The Current Usage
table lists both online time and sessions used by the user, with columns for
daily, weekly, monthly, and total usage. The Current Usage table appears only
on user accounts that you have previously established; that is, it does not
appear during initial user setup.

For a user who has exceeded his quota, Cisco Secure ACS denies him access upon
his next attempt to start a session. If a quota is exceeded during a session,
Cisco Secure ACS allows the session to continue. If a user’s account has been
disabled because the user has exceeded usage quotas, the User Setup Edit page
displays a message stating that the account has been disabled for this reason.
