Created attachment 1398517 [details] Solution patch Description of problem: Despite non-zero interface_fadeout, interface is deleted immediately if ifLastChange is more than interface_fadeout ago. Version-Release number of selected component (if applicable): net-snmp-libs-5.7.2-28.el7.x86_64 net-snmp-5.7.2-28.el7.x86_64 net-snmp-agent-libs-5.7.2-28.el7.x86_64 net-snmp-utils-5.7.2-28.el7.x86_64 How reproducible: Always Steps to Reproduce: 1. Set interface_fadeout 60 in snmpd.conf ; restart snmpd. 2. Add dummy1 interface to the system: $ ip link add dummy1 type dummy 3. Query list of interfaces via snmp. Make sure that dummy1 interface is present in snmpd output $ snmptable -v 2c -c public localhost ifTable 4. Wait for more than 60 seconds (interface_fadeout time) 5. Deleted dummy1 interface from the system: $ ip link del dummy1 6. Query list of interfaces via snmp. $ snmptable -v 2c -c public localhost ifTable Actual results: dummy1 interface disappears from snmpd output immediately after it is deleted from the system despite non-zero interface_fadeout Expected results: dummy1 interface will be present in snmpd output within interface_fadeout seconds after the deletion Additional info: Solution patch attached
