Hi,
I have similar issue with Nexus 7706 chasis running NXOS version 7.3(5)D1(1).
It's not sending coldStart traps when did a power on of the chassis.
The only deffennce here is the snmp source-interface , which is loopback interface in my case .
So just wondering is it due to the same bug CSCvf56548 .
Thanks
