Using show CDP neighbors detail you will get this info: Device ID: Entry address(es): IP address: Platform: Capabilities: Interface: Port ID (outgoing port): Holdtime : Version : advertisement version: Protocol Hello: VTP Management Domain: Duplex: Management address(es):

BUT IP is not a good identifier because it could be modified manually, I would prefer to use show version or show inventory to get the serial number of the device.
