Re: SNMP On iSeries -- MIDRANGE-L

Mike,

Bringing up SNMP is very easy. Of course, you have to configure the SNMP
parameters. Use CFGTCP, then option 20, and configure SNMP. If you need some
examples of what to put in here I'll extract some stuff from our manuals and
send it to you.

Depending on the SNMP management software you may need to register the IP
address of the AS/400 with it. Some management software will ignore a system
unless it is registered.

Once SNMP support is activated on the AS/400 (strtcpsvr *snmp) you should
see the AS/400 in your network management software. The basic information
should be available (system information, network interfaces, etc.). The
AS/400 generates a cold start trap message during IPL.

For application level stuff you will need to program an SNMP sub-agent. This
is a program (usually written in C) that registers to the AS/400 SNMP
support, and handle trap messages, and other SNMP functions. I've only done
the trap message support, but I think you should be able to do the set and
get functions if you want. That will require creating the MIB documents. IBM
provides the MIB documents for the system, SNADS, and a few other items.
After the basics you've got to do this yourself.

I believe you should find some sample code in the System API Reference
manual that covers the SNMP functions.

Good luck!
Patrick
