snmpd in HA environment

Hi,
 
I would like to use the snmpd agent for the only purpose (for now) to
sent traps to a Network Manager but in an HA (High Availability)
environment.
I would like to know if the snmpd agent has some built-in HA
capabilities i.e. having two snmpd running on two different nodes - one
active instance and the other one on stand-by mode. The both agents
would be notified when an alarm occurs but only the active snmpd would
map this error to a SNMP trap and would send it to the Network Manager.
And when the active has a problem (e.g. the node is down) the stand-by
instance would become active.
 
To support this kind of functionality the 2 agents should communicate
together.
 
Has someone encountered the same issue?
 
Thanks,
Eugen
