I’m getting these SNMPv3 errors on our Extreme Control appliance from random switches;
SNMP_V3_NOT_IN_TIME_WINDOW(1411) from device: 192.168.64.87 with message: org.snmp4j.asn1.BERInputStream@d5ffd43
SNMP_V3_UNKNOWN_SECURITY_NAME(1404) from device: 192.168.231.20 with message: org.snmp4j.asn1.BERInputStream@7688ed06
They're talking fine to EMC, no alarms.
Any advice on what these errors are caused by please?

That could be a duplicate snmp engineid.
What type of switches are causing this?
You can check the snmp engineid issue with this: https://gtacknowledge.extremenetworks.com/articles/Solution/NAC-loses-contact-with-switch-after-changing-the-SNMPv3-engineid/
