This counts how many Packet-of-Disconnect success notifications the gateway has sent back, confirming to the RADIUS server that a requested session teardown actually completed. Because AAA servers rely on this acknowledgment to know a session is really gone, a gap between cagwPodRequestsRecv and this counter means some disconnects are stuck, leaving stale sessions holding IP addresses and bandwidth the billing system already considers freed. For example, a gateway that received 340 POD requests but only sent 335 success notifications has 5 sessions that look torn down on paper but are still consuming resources.
