I have a fresh new EMC 22.214.171.124 installation.
I have added new X460-G2 device using ZTP+ and everything was fine.
However, after 5-6 minutes I have an "Contact lost" alarm.
Device is fully IP-reachable: ping gives the response, "open device terminal" from EMC is working, I can also poll device with MIB Tools using default SNMPv3 creds.
Both SNMP processes have "ready" status on the switch.
EXOS is 126.96.36.199 patch1-4
When I rebooted the EMC, then I have "Contact established" back.
But after few minutes EMC lost the contact with the switch again.
Looks like it is EMC issue.
Any ideas ?
