I'm having issues with DCNM discovering some Nexus 7K's. Shallow discovery seems fine. I enter the Nexus and its snmpv3 credentials in
DCNM> Admin>Data Sources>LAN
I enter the device as a single device in a switch list and it finds it as manageable. I select the device and it goes into Discovering.
Sometimes it completes this part and allows me to go to Deep discovery. Other times I get snmp timeout messages. I have had it complete a deep discovery and show up on my topology map only for it to disappear a day later again with snmp timeout errors. I've confirmed the snmpv3 credentials work with a 3rd party MIB browser which lets me test credentials and all is ok with them.
My first question is
The DCNM server seems to have an incorrect time. Is this a possible issue ? If so how do I set the time ? I've looked all over the GUI and can't find any place to set it. Is it taken from the VM platform or is it set independently ?
Are there any other issues that may cause discovery problems ?
