Hello, Switch100 is two 9300 stack, and SW10 and SW20 single switch 9300. Three switches connect each other with two cables. show cdp neighbor shows the connection like below, which looks like unreasonable. Did I miss some something in these checks? Anyone can explain it?
Thanks for your reply. Something was wrong with the diagram. Now i updated it. All three switches are in same subnet. Can you take at it again?
If you change the SN numbers and device names with something else, it should be fine. But make sure you are consistent in the change.
