Hi Dustin,
Many thanks for the feedback,

I know id like an option to force v2 without a fallback, this is

When the snmpforce_v2 setting is used and matches the device, then
there should be no fallback to v1.
, if also like an option to
automatically output an snmp discovered credentials file so that in
the event a mode passes discovery once it will retry those
credentials
in the event the node is dropped for whatever reasons
It's a good suggestion. This can kind of already be achieved using the
get_community option (not supported in Netdisco 2 yet) to call out to an
external program to retrieve the community for a device.
Another option would be to get Netdisco to hang on to the communities
after device deletion/expiry, but I'm reluctant to do this, as an admin
probably assumes when they delete something that all its properties are
wiped.
we have about 10 different strings in use for ro and rw so discovery
can bog down sometimes
My new config format for SNMP Auth in Netdisco 2 should handle this
case well. You can easily map different R/O, R/W communities and v3
users to groups of devices.
I know I wrote a script to use onesixtyone to run discovery and then
output to a discovered snmp strings file but it would be nice to have
that integrated
A script using our DBIx::Class layer should be able to do this without
much difficulty.
regards,
oliver.

Not that I recall. There was a recent patch from Bill to fix the
fallback from v3.
There are options to go the other way: force SNMP version by device
name/prefix/etc:
snmpforce_v1
snmpforce_v2
snmpforce_v3
Incidentally I'm working on a new config syntax for SNMP Auth in
Netdisco 2 to allow more control, e.g. duplicate v3 usernames,
matching
communities to IP prefixes, etc. If anyone has particular use cases
they'd like supported, now is the time to let me know.
regards,
oliver.

any option to make hanging on to communities a configurable setting and then
after x settings have it drop the community?
also is netdisco 2's polling engine ready for prod, we're still using netdisco
1's polling engine with netdisco 2

That was indeed the problem, the BlueCoat mibs were not in
netdisco.conf.

I think I've worked out in my head a way to do this. I'll add it to the
wishlist/tracker.
also is netdisco 2's polling engine ready for prod, we're still using
netdisco 1's polling engine with netdisco 2
I think the poller is close, but not 100% parity with Netdisco 1. We're
still finding occasional (relatively minor) logic errors handling some
of the many config options which control macsuck/arpnip/discovery. So it
depends how complex your configuration is.
Remember that you can switch between the pollers, as long as you only
choose to use one at any time.
regards,
oliver.
