Import SNMPv3 credentials for multiple devices

I'm trying to import SNMPv3 credentials similar to the way SSH credentials are imported in this article: https://support.infoblox.com/s/article/3636. Any help is appreciated on the exact format of the file.

 

Thanks.

I can't quickly find a way to do that, but do you really need to import creds per device?  Is SNMP guessing not sufficient?

 

If you're trying to update existing/working creds, you can either:

1) Add the new ones to the global list with a higher priority and then via the NetMRI CLI - "reset snmp".  That forces guessing for all devices.

2) Use a perl or python script that executes on the devices of interest.  Via the API, it sets the values for each device in the DB and initiates a Discover Now for each one.  I used this method when migrating from v2 to v3 and also to update the v3 ones.

I had actually found this script on the site. Unfortunately, I can't find the original posting. And I can't attach it here, so here is the text of the perl script. This seems to work well.
