SNMPversion =1 or 2
This only really affects the use of the awesome GetBulk operator
64-bit counters should be disallowed in snmpv1, except there are some broken snmp implementations out there that do not support getbulk properly, but do have working 64-bit counters...
Hi Richard, there are some Nodes that do not "speak" SNMPv2, we found that especially Juniper Nodes did not get discovered when using SNMPv2. What we also found is when we manually click the "test" button in the Node Details below the SNMP Settings the node gets discovered.... but we can not do that manually for a large number of nodes (>10.000)
here are all of the properties that I set when creating a node (from Perl); I've highlighted the ones I think you are missing. I have thousands of juniper switches and a couple of dozen juniper routers, and they are getting discovered okay (as far as I can tell)
'IPAddressguid' => ip2guid($ip),
'RWSNMPV3AuthKey' => 'None',
'RWSNMPV3Context' => 'None',
'RWSNMPV3PrivKey' => 'None',
'RWSNMPV3Username' => 'None',
'SNMPv3AuthKeyIsPwd' => 1,
'SNMPV3AuthKey' => 'None',
'SNMPv3AuthMethod' => 'None',
'SNMPV3Context' => 'None',
'SNMPv3PrivKeyIsPwd' => 1,
'SNMPv3PrivKey' => 'None',
'SNMPV3Username' => 'None'
we discovered that we only need to open the Node in "Manage Nodes" and hit Send and then the node is successfully discovered, However we have more than 10.000 Nodes and we can not do that for all manually.
Hi Richard, what calculation is behind IP Address to GUID? is this a "known" function? Thanks
Nevermind, we figured it out
