  • Acct-Input-Octets: Number of bytes received from client(lower 32 bits).

Interim Accounting Requests

Support for RADIUS Interim Accounting Requests was adding in 4.4.0-110 and 5.0 on June 07, 2012. Periodic accounting requests will be made to each RADIUS accounting server at the specified interval for each connected user. Configuration of RADIUS Interim Accounting Requests is done using the wan.conf file under 4.4 and /etc/inetics.d/l2tp.conf under 5.0 using the acct-interval <interval in seconds> argument to the radius-server VirtualTemplate command.

Example sending Interim Accounting Requests every hour (3600 seconds)

radius-server host 192.168.0.1 acct-port 1813 auth-port 1812 key password acct-interval 3600
