Session States
A session may be in one of three possible states:
l Active—An active session is one for which the RADIUS server has received an accounting start message and
has not received a stop message, which indicates that service is being provided by a NAS on behalf of an
authorized client.
While a session is in progress, the NAS sends interim accounting update messages to the RADIUS server. This
maintains up-to-date traffic statistics and keeps the session active. The frequency of the accounting update
messages is configurable in the RADIUS server.
l Stale—If an accounting stop message is never sent for a session—for example, if the visitor does not log out—
that session will remain open. After 24 hours without an accounting update indicating session traffic, the session
is considered ‘stale’ and is not counted towards the active sessions limit for a visitor account. To ensure that
accounting statistics are correct, you should check the list for stale sessions and close them.
l Closed—A session ends when the visitor logs out or if the session is disconnected. When a session is
explicitly ended in either of these ways, the NAS sends an accounting stop message to the RADIUS server. This
closes the session. No further accounting updates are possible for a closed session.
