Dear Igor (or anyone else interested in this problem), I am trying to have one master agent, and multiple AgentX subagents, each implementing a row of the same table. It sounds like you have done this, but I have not been able to. From what I understand you to say, you call netsnmp_create_handler_registration(), with oid set to the entire oid of a column object (the first one, I assume), including the index, then set range_subid to the OID_LEN of the entire oid, including the index. Then set range_ubound to the upper bound of the set of rows you want to handle. In my case, it's the same as the index, since I want one row each. Then the handler will be called for ALL columns with that index.
Do I have this right? I don't really understand this. How does netsnmp_create_handler_registration() know that you want all the columns for that row, and not just the single column at that row? Also, how do I tie the handler to netsnmp_register_table_data_set()? You need to pass that the oid of the table. Have you tried this? Have you seen any other mail or docs about this? Do you have any more detailed code examples? Thanks, Phil Gillis -----Original Message----- From: Grasic Igor [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 01, 2004 3:18 AM To: [EMAIL PROTECTED] Subject: Re: Adding interfaces to the IFMIB via AgentX Hello codders, John, The third way to register some rows in table via AgentX is to use 'netsnmp_register_handler' with set 'range_subid' and 'range_ubound' to the point in the oid, where is defined column number for the object and with the oid for the whole (!) row, included with the ifIndex at the end. In that way registered handler will always get only the request for the registered ifIndex, but for all column objects. Of course, in the handler you shouldn't forget to implement serving multiple request and MODE_GET_NEXT requests (depends on the flags)... Anyway, if you gonna look at mailing list, I already made some questions concerning the same problem you have. I tried with registering intances, but... if you have big number of objects, memory consumption of the running agent drasticaly increase. I hope, that this will help you some way. Enjoy, Igor G.

Development Engineer Iskra Transmission, d. d., Ljubljana Stegne 11, SI-1000 Ljubljana, Slovenia www.iskratr.si, www.iskratr.com SNMP Coders, I have searched online for a couple of days now, and have read rstory"s faq quite throughly, but I can"t seem to find a good way to register additional rows to an existing (standard) table such as the ifmib through AgentX. The only way I have found to do this is to register each OID in the table for each inteface using netsnmp_watcher and netsnmp_instance... which means alot of registering, and alot of function handlers. This is very inefficient and non-extensible. AgentX will be running on another machine and I want that sub agent to add in (register) its ethernet interfaces to an exisiting agent. That way, when the network manager walks the IFMIB of the exisiting agent, it will be able to see the interfaces on the exisiting agent AND the interfaces on the machine that is running the subagent. I hope this makes sense. If you need me to draw up some pictures to explain more clearly, let me know.
