Hi,
We have a DMS of 20 agents in main/failover configuration (10 DMA-pairs). We have configured an SNMP manager to send traps northbound using SNMP v3. We have not selected "Send all notifications via one DMA".
However - the SNMP Manager settings are global to the DMS and means that every agent gets the same Context Engine ID. This poses a problem norhbound when doing a failover switch where msgAuthoritativeEngineBoots and msgAuthoritativeEngineTime will differ between the agents in each pair and may be lower, which trigger some security blocks.
One solution to this would be to use unique Context Engine IDs for each agent. Is it possible to do so by editing SNMP Managers.xml on each agent? Or will a sync between main/failover or across the DMS break the individual configuration?
We have done some further research and the problem seems not to be Context Engine ID which can be the same for all DMA:s but authoritative engine ID which should be individual to each DMA. But in practice when doing a failover switch the new main DMA gets the same authoritative engine id as the old main DMA had. This poses a problem for us northbound because msgAuthoritativeEngineTime must be an increasing value which is not the case after failover in our case. Also, it could be that msgAuthoritativeEngineBoots also need to increase, but not sure.
