All RADIUS accounting modes can be enabled for IPoE sessions: queue instance accounting, host accounting or session accounting.
With session accounting, a RADIUS accounting start is generated when the first host of the session is created and an accounting stop when the last host of the session is deleted. The generation and interval of periodic interim updates can be configured. Optionally, triggered interim update messages can be generated when a host is deleted from the session or an additional host is associated.
A unique accounting session ID is generated for the IPoE session and is used in RADIUS session accounting. The IPoE session accounting session ID can be included in the RADIUS Access Request message the config>subscr-mgmt>auth-plcy> include-radius-attribute acct-session-id session command.
This accounting session ID can also be used in RADIUS CoA or Disconnect Messages to target the IPoE session.
