Instead of using SNMP TRAPS I would like to use INFORM requests. When I receive TRAPS everything is working correcty. When I receive INFORM requests, the source interface is reported wrong.
snmp-server trap-source Loopback0
snmp-server source-interface informs Loopback0
snmp-server enable traps snmp linkup
snmp-server enable traps config
snmp-server host 10.101.1.15 inform version 2c public
snmp-server host 10.101.1.15 version 2c public
The TRAPS report their source address as Loopback0 but the INFORMS report their source address as FastEthernet0.
