core and switch both have different IPs in cdp neigh for the same switch

not quite sure why, but the core thinks a certain switch is x.x.x.103 when it is actually x.x.x.2. They both show the same phyical connections so i know its definately the same switch. Only issues I can think of is the two uplinks to the switch are etherchanneled. I ping the address the core has and nothing. Not sure how the core gets the ips, whether its just a table that needs to be reset or something. Thanks

Verify the switch holding IP address x.x.x.103 does not have any interface holding such IP

with a show ip interface brief | ex una command.

sorry, nothing on either our core switch or the x.x.x.2 switch when using the command that points to x.x.x.103

Please post show cdp neigh from the switch seeing the incorrect CDP information and show ip interface brief | ex una from the switch sending the CDP.
