I have a Cisco 3850 fiber switch with a single 10G link to a Cisco Nexus 7009 ("N7K"). The N7K links to the fiber switch's Te1/0/12. What I am seeing in the CDP table is switch2 and switch6 are also showing up via Te1/0/12. Switch2 is on Te1/0/7 and Switch6 is on Te1/0.2. In the CDP table below you can see the correct CDP entires as well as duplicate entires for Switch2 and Switch6 both coming off of Te1/0/12 where the N7K is.
My question is, what could be causing these duplicate entires for switch2 and switch6?
Thank you much,
