I have a system where network devices will generate SNMP traps using v3 to
ensure that the data is encrypted across a WAN.
My event collector however will only support SNMPv2. Changing to a different
collector is not an option, it collects and analyses event from a number of
sources and not just network devices.
I need to find a method of receiving an authenticated and encrypted trap from
my network device, and then forwarding this to my collector using SNMP v2 over
a local LAN. This conversion would be on a trusted network so the lack of
encryption between the converter and the collector is no longer an issue.
Can snmptrapd do this? Is there any other component I need?
How do I configure it?
Is there any other solution?
Any other points I should be worrying about? I know about the IPaddress issue
with the forwarded message
A Windows implementation is preferred but Linux is not out the question.
I think I have successfully configured snmptrapd to receive SNMP v3 traps. I
can't figure out however how to send them on to my event collector using SNMP
v2c TRAPS. I should not need to process the MIBs as the event collector
understands SNMP v2 MIBs. The documentation on proxying only appears to talk
about proxying SNMP v2c gets to an SNMP v3 device. This is not what I need.
