UDT shows a node's IP address and MAC address were discovered and associated with a switchport that are monitored via UDT, in a subnet IPAM monitors.
But IPAM Details are not available in UDT.
The link for that shows:

There's a previous thread about this exact issue--but it was never answered.
- The endpoint is monitored by UDT
- The IP-MAC pair are known, but this is a Layer 2 switch providing the MAC address, and the upstream NX-OS Distribution switch manages the ARP/IP. Is the problem due to the upstream gateway being a Nexus L3 switch?
- The IP address is managed by IPAM
- Polling the subnet and device are successful
- *** I'm unaware of the process by which one can view / verify the permissions for viewing the device and subnet are appropriate. Where is this accomplished or seen?
Swift packets to all who help!
