Configuring Cisco Discovery Protocol
Purpose
To review and configure the Cisco discovery protocol. Discovery protocols are used to discover
network topology. When enabled, they allow Cisco devices to send periodic PDUs about
themselves to neighboring devices. Specifically, this feature enables recognizing PDUs from Cisco
phones. A table of information about detected phones is kept by the switch and can be queried by
the network administrator.
port‐string (Optional) Specifies the port or ports for which to display Neighbor
Discovery information.
