We use this currently on IPSentry. Here is the page that talks specifically about how to poll an SNMP OID and then take action based on what it finds acceptable. You can even import your MIB files for things to make finding the right OID easier.
Thanks for the reply. I've been fiddling with IPSentry and it looks fine. But I do have a problem. :-(
When I read the OID of "Interfaces.ifNumber" I get 9 on one of the boxes. This number is correct. But I cannot get IPSentry to read the
and so. I get no values returned. By using snmpwalk, I manage to read the values. I can also read the values by using WhatsUP Gold and other programs.
Please advice on this if you know any workarounds.
