The Cisco Discovery Protocol (CDP) is a proprietary Data Link Layer network protocol developed by Cisco Systems. It is used to share information about other directly connected Cisco equipment, such as the operating system version and IP address.
Device connected to CISCO CDP enabled switch can sniff CDP packets and gather inflormation about port like switch name, trunk and VLAN IDs, port number like Gi1/5.
VMware support it by default and it can be seen in GUI in networking tab.
AIX / VIOS doesn't support that by default but it can be gathered by script using tcpdump.
Script for CDP on AIX can be downloaded here:
