Question from the audience at Empower in London:
- Can I have all my third party devices send SNMP traps to one IP address (one DataMiner node), and will DataMiner then forward it from one node to the other, so that it ends up with the proper associated element for each specific trap (irrespective of which node that element is hosted on)?
- When the swarming is released, will this then also work if the above is possible?
- A single destination IP address is very convenient (as this has to be configured on the various involved third party products, and you do not want to change that), but it then also represents a single point of failure. Would it still be possible to use on that node a classic main / backup node (with virtual IP address moving in between them) to deal with that, in combination with the upcoming swarming leveraged across the other nodes?
Or any other recommended way to deal with SNMP traps?

If we can send the SNMP trap to any DMA, would this be a use case for Anycast, as SNMP uses UDP and is stateless? Could you add the same /32 IP to each DMA, then use your favourite routing protocol to update the routing tables, Then failover wouldn't be an issue.

Interesting idea! I would indeed expect this to work like you explain it, but I’m not immediately aware of anybody setting this up in that way. But it sounds feasible.
