Neighbor Discovery broken on CRS - all neighbors are. on master-port

CRS, 6.38.7

Neighbor discovery shows all neighbors to reside on the master port. This makes the whole thing pointless. How to make it show neighbors on their actual interfaces? Thanks.

It's not broken. Working as intended.
That is the whole idea of master-port. All ports are directly connected to switch chip and all traffic passes directly. The cpu only sees master-port.
But in neighbour table you see the mac address of the device and then you can use the switch fdb table to see the port to which it is connected.
