Tcpdump is a powerful tool for capturing and analyzing network traffic, and it can also be used to filter CDP (Cisco Discovery Protocol) and LLDP (Link Layer Discovery Protocol) packets. Both CDP and LLDP are data link layer protocols used to provide information about other directly connected Cisco equipment, including device type, uptime, IOS version, and directly connected IP addresses.
