| | ===== Subscriber host connectivity verification with session termination (Subscriber Host Connectivity Verification) ===== |
| | Monitoring the activity of a static IP L2 subscriber (a subscriber for whom RADIUS returned the flag VasExperts-L2-User=1 during L3 authorization). |
| | |
| | If there is no traffic from the subscriber for ''bras_subs_shcv_interval'' seconds, fastDPI starts pinging the subscriber by sending a unicast ARP request on behalf of the subscriber gateway. The wait time for an ARP response is ''bras_subs_shcv_retry_timeout'' seconds. If no response is received for ''bras_subs_shcv_retry_count'' consecutive ARP requests, or if the ARP response contains a different MAC, the subscriber is considered inactive, their authorization status is reset, and the accounting session is terminated. |
