my PI1.2 running on ESXi5.0, successfully discovered all the NAM modules. however, i couldn't send https request to the NAM modules. i sniffed the traffic. All it does is send get SNMP requests and SSH requestes. why not HTTPS? i put the right HTTPS credentials. I opened multiple tickets but cisco TAC team seems to be occupied or the product is new and kind of hard to figure out. i ran into the same issue with Nexus 1000v when it was relatively new. I am sure Cisco TAC is good on Nexus 1000v now.
