I'm trying to configure some new Juniper gear(SRX and EX) with SNMPv3 and getting it added to a new SW install. SW is saying my device is not responding, and my device is saying it's dropping the packets "because they referenced an SNMP engine ID that was not known to the SNMP engine". I've tried various combinations of changing the engine-id with no luck. Does anyone have any experience that I may be overlooking? I've previously added the same type of devices with SNMPv2 without problems.
