The Link Layer Discovery Protocol (LLDP) is a vendor-neutral Layer 2 network protocol used by network devices, especially switches, to advertise their identity, capabilities, and neighbors on an IEEE 802 Local Area Network (LAN). If configured, LLDP messages are sent out periodically as frames with the destination MAC address of `01:80:c2:00:00:0e`. The default time interval is 30 seconds.

If you are using a hypervisor like Hyper-V with a virtual switch configured as "External network" which is shared with host where NETworkManager is running, you may not receive any packets. This is because the virtual switch does not forward the LLDP or CDP frames to the host. You may temporarily change the virtual switch to "Internal network" or "Private network", if you want to use the Discovery Protocol to see which switch or router your device is connected to. You can also verify this behavior by using Wireshark.

A port is a logical construct that identifies a specific process to which network traffic is to be forwarded. Ports are identified by a 16-bit number, known as a port number. Port numbers range from 0 to 65535, but only ports numbers 0 to 1023 are designated as well-known ports. Well-known ports are those registered with IANA for common services such as HTTP (port 80), HTTPS (port 443), FTP (port 21), and SSH (port 22).
