Using proxy means that you need a full agent running on the remote devices. Obviously this will consume more resources than an AgentX subagent. XQ> 2.

There is a line in RFC 2741: An AgentX XQ> subagent can connect to a master agent using either a network transport XQ> mechanism (e.g., TCP), or a "local" mechanism (e.g., shared memory, named XQ> pipes). How about net-snmp? Yes, you can use named pipes for AgentX. In fact, that is the default for net-snmp. ------------------------------------------------------------------------------ Cloud Services Checklist: Pricing and Packaging Optimization This white paper is intended to serve as a reference, checklist and point of discussion for anyone considering optimizing the pricing and packaging model of a cloud services business.
