The Cisco 10000 router supports only time-based SSG Prepaid for a service connection. Quotas are
measured in seconds. You cannot change the unit of measure.
The Cisco 10000 router does not support returning a quota when the connection is idle.
After a user runs out of quota and then replenishes the quota at the billing server, SSG receives the
updated quota and resumes the connection only after the next reauthorization.
You must enable SSG accounting before you can use the SSG Prepaid feature. SSG accounting is
enabled by default. If it has been disabled, reenable it by using the ssg accounting command in
global configuration mode.
The SSG Prepaid feature requires the AAA server to support prepaid billing.
You must configure the SSG to send Attribute 55 in accounting requests.
