1. Switch from SNMPv2 to SNMPv3 (Dean, Barry)

I have a number of devices that have been detected and discovered using SNMPv2
and this is reflected in the snmp_ver column in the device table as well as the
entry in the community table.
I'd like to flip them over to using SNMPv3. (There is nearly 500 of them!)
The only way I know to do this is to update the community table with the name
of the SNMPv3 credential set defined in deployment.yml. Which is OK, but not
all of my team are comfortable with SQL!
Is there another way, short of my writing a script to do it? A dropdown
selection on the device Details page would be the ideal, but I'll take anything
I can get!
I have visions of someone forgetting the WHERE clause on the UPDATE and finding
myself pulling the old community table out of the backup!
Thanks

Hi Barry
I hope you can do this more easily using the configuration file.
If you set up device_auth with two tagged stanzas, one for v2 and one for
v3, then use "no" and "only" options, you can control what is used for each.
So as a test, take one device IP, add it to the "no" option for the v2
stanza, and to the "only" option for the v3 stanza, and restart the backend
(or test at command line with ~/bin/netdisco-do discover -d 1.2.3.4 -D).
Netdisco should spot that it can then only use the v3 stanza in the config
for the device, and flip over to using it.
If it does not, I'd like to fix that bug :-)
regards
Oliver.
