Forward v2 informs as v3 informs with snmptrapd

Dear all I'm looking for a way to receive v2 informs with snmptrapd and forward them as v3 informs to another trap receiver. I did not find a way to do this with netsnmp, as the forward directive does not support any snmpoptions. Can this be done somehow? A solution might be, to pass the v2

Sending trap/inform to the sender of an snmp request

Hi In our setup, we have multiple devices which are managed by two NMS, where only one is active (second is for standby). I'm looking for a possibility to send traps automatically to back to the current 'client' of the agent (instead of hardcoded trap receivers in snmpd.conf). Is this supported b

Hi all In the netsnmp wiki there is an example of how to configure the proxy if proxying is used with multiple devices with the same oid. Instead of using an snmp v2 context (-c) I want to use the snmp v3 contextName/contextEngineId (-n). Does this work accordingly? E.G. having the folloginw
