Mathias,

I am curious how you were able to get that to work?  I have had to do the
painful route of destroying a pingable model and then recreating it as a v3.

I have in the past attempted to change the Model Class to SNMP.  The Edit on
the SNMP Community String is not available and the field is blank.  

I have gone into the Attrib editor and try to force the change (after
changing the Model Class) that way and received the error: "Model Write
Failed: The Community_Name attribute does not exist for the model."

I am currently using 9.2.0

Stephen

You can convert a device from v1 polling to v3 polling by editing
Community_Name and CommunityNameForSNMPSets, you just have to format the
credentials correctly.

The format is        #v3/<secLevel>:<optional flags><authString>:<optional
flags><privString>/<username>

secLevel is P for authPriv, A for authNoPriv, and N for noAuthNoPriv

optional flags let you specify non-default auth or priv protocols, SHA^ or
3DES^ (or MD5^ and DES^ if you changed the default protocols in .vnmrc)

the authString, privString, and username are all from your credential set.

so for example,
#v3/P:thisismyauthpassword:thisismyprivpassword/someuser
or
#v3/A:SHA^thisisadifferentauthpassword/otheruser


You can also add a context string before the username:
/<context>/<username>

See Spectrum Modeling IT Infrastructure Admin (9.2.1 docs, 5167 in older
docs) for many examples.
