Sorry for the delay, but you have hit a complex question that makes it harder for us to answer than you'd like (and hence no one has answered you yet). But you're not going to like the answer anyway, because it's "no you can't do that". There is no way to get the correct ifNumber count when you have a subagent implementing a portion of the ifTable. The best alternative, unfortunately, is to have the master agent communicate with your PPP daemon not over agentx to collect the interface rows but to instead use some other communication mechanism (RPC, shared memory, whatever) and modify the master agent to collect those devices when returning answers for the ifTable. Merging tables generally sucks. AgentX promises to help out with that, and it does work in some cases, but it's hard to implement and isn't as widely supported as it should be. In our case, row-merging isn't well tested either. -- Wes Hardaker Sparta, Inc. ------------------------------------------------------- All the advantages of Linux Managed Hosting--Without the Cost and Risk!
