Uplink IP
I have another curious issue. I am running multiple switches in my environment and when I look at the connected neighbors every link between the switches has a foreign IP that does not match the IP ...

I got your private message and forwarded the diagnostics file to the higher tier of NETGEAR Support to check it.
I just got feedback and it was confirmed that there are network parameters set to 169.254.0.239. This is the cause on why the switch advertise this as its Mngt IP Address. The only way to clear this is to factory reset the switch and reconfigure it. To reconfigure it, be sure to delete it from NETGEAR Insight then re-add it. Do NOT reload the configuration on the switch but be sure to reconfigure the settings via NETGEAR Insight.

From the image you have attached, are you able to login to the GC728XP switch using the Management IP Address you assigned to it?
The 169.254.X.X address shown as the Mngt IP Address under the Neighbor Info section is a self assigned IP Address. This means it didn't get a DHCP address or it has a static address at the time of LLDP message. It is possible that there is an interface on the switch that has a self assigned address and is sending that as its management IP address.

Ok, so last night, I attempted to remove and restore switches to factory condition.
Moved backward starting with access and leaf switches then to core. Results, no luck, still get the zero conf address as the mgmt IP for the interface connecting to the core. The interesting thing is when I removed the core switch from the app, it came up and accepted the Static IP address from my DHCP server. When I added the switch to the insight portal, it dropped the reserved IP and took another. I have included the event logs concerning the Core switch. So what else can we do? Do I need to RMA the core switch? It works but not correctly, and that is always a concern.- JeremyseJun 22, 2020Tutor
New wrinkle:
Yesterday I performed the following steps:went in and . then di.
1. removed all the switches via the phone app
2. factory reset all switches via the reset button on the switches
3. disconnected a fiber port on the LAG
4. added Core Switch via phone app
This came up with correct IP and all connected neighbors had the correct Mgmt IP
5. Added Leaf Switch
This too came up with correct IP and neighbors
6. Created LAG between Core and Leaf switch 10G sfp+ ports 27 amd 28
after this step the mgmt IP for the leaf switch reports as 169.254.0.239, and the other switch which should show a mgmt ip of 10.0.0.5 attached to port 4 of the core shows 169.254.0.239 for a mgmt IP.
So the question now becomes , Do I RMA the core switch becuase none of the steps I took resolve the issue.
