We have several systems monitored using SNMP v3, but after a reboot of these devices they are no longer returning data. Using SNMPWALK I can query each one using the user ID and password configured within the template.

Searching through other posts it looks like a duplicate snmpEngineID, but I have checked each device and the IDs are unique.

Does Zabbix store the snmpEngineID with the device configuration and if so, how can I find out what snmpEngineID Zabbix has for each device?

We have tried removing the device from the template and then reading it, but this did not resolve the issue.
