No - the SNMP daemon expects to be a single process, responsible for handling all network management requests. The idea of running multiple snmpd processes is not the normal mode of operation. You *might* be able to start snmpd as a "single-threaded" service, though I'm not sure it really buys you much. And delaying the agent startup until the first request comes in, means that this first request is more likely to time out (and be re-sent). My gut reaction is that the cure is worse than the disease! > - is this one standalone deamon limitation specific to net-snmp only? > - do other snmp vendors support multiple agent deamons?

No - if you start multiple daemons (listing on different ports), then that's what you'll get. That's something I do all the time, when developing new versions of the software (while leaving the "production" agent in service). But that's a relatively unusual scenario. It would be more usual to run a single daemon listening on multiple ports: snmpd address1:port1 address2:port2 etc The only reason for running different agents on different ports would be if you needed to return different information (and hence have a different configuration and/or binary for each agent). But that counts as "advanced use of SNMP". If you're still getting used to the basics of SNMP, then I'd suggest you stick to the normal model until you've gained a bit more experience and familiarity with how things work.
