Module: ZHONE-COM-IP-ZEDGE-NAT-MIB
OID (symbolic): ZHONE-COM-IP-ZEDGE-NAT-MIB::natNumExpiredBindings
OID (numeric): 1.3.6.1.4.1.5504.4.1.16.2.2
Node type: OBJECT-TYPE

Description: Number of bindings that have been expired. A binding is expired when it has been idle for a period longer than the configured timeout.
What is natNumExpiredBindings?
This object reports the number of NAT bindings that have expired after being idle longer than the configured timeout (natTcpTimeout or natUdpTimeout). An admin checks this to understand binding table churn and confirm that idle connections are being cleaned up as expected. For example, a high expired-bindings count alongside normal current-bindings count would indicate healthy timeout-based cleanup rather than a leak.
