OK - got it going...
First assumption is that you have valid SNMPv3 credentials.
Second assumption is that you can log in as Admin:
- Make sure the SSL certificates are valid.
- In the License Area (lower-left) enable the Remote UI SSL. Restart the unit.
- Under the Settings / Network settings / SNMP
-- take the tick out of SNMPv1
-- tick ON the SNMPv3, and select User
--- enter the proper SNMPv3 user credentials, click OK to save.
- Restart the unit, and wait about two minutes.
- Re-poll from LanSweeper.
Profit! And, now you can tick off another problem child from the lists.
Enjoy...
