Hi,
Just wondering if anyone has experience of connecting Cisco Nexus 5548UPs (or any device in the N5K range) to Cisco Prime Data Center Network Manager (DCNM)? We are migrating from end of row MDS9500's to top of rack N5K's and the legacy Fabric Manager we were using to manage the zone sets on the MDS's doesn't work with the N5K's so we need to move to DCNM.
I've been able to get the MDS 9500's connected as a DCNM data source but can't get a N5K to connect. Some detail of the N5K addition process:
When trying the various local and AAA accounts, I can see the requests hitting the ACS server and being authorised. I've tried removing the AAA config on the N5K's which made no difference when trying local accounts.
The errors we get vary depending on which Auth-Privacy setting is used - sometimes it's a timeout message "Discovery is taking longer than 2 minutes. Please return later to check status in table", sometimes "Cannot authenticate snmp user:null/<ipAddress> Unknown User or Password" <- This one is interesting, why does it say "user:null"?
Does anyone have experience of this? If so, would you mind sharing any insights or maybe config on the N5K (which is where I suspect the issue is)?
Cheers

- Go to Admin > Data Sources
- Fabric Seed Switch = IP of Mgmt 0 on N5K
- SNMP = v3/SSH
- Auth-Privacy = tried all options
- User name = tried local and RADIUS user accounts
- Password = as appropriate
- Limit discovery by VSAN = unticked
- Enable NPV discovery = ticked (default)
