CDP Settings
Using the CLI to Configure CDP
From the global configuration mode, enable cdp with the cdp auto‐enable or cdp enable commands. Specify the hold time, transmit frequency and optionally an authentication code using the cdp hold‐time, cdp tx‐frequency and cdp authentication commands. To disable cdp, use the cdp disable command. Use the show cdp command from Executive mode to display cdp settings, or to view neighbor entries or cdp traffic statics.
