| 4.1.5 |  | Disabling CDP |

| To disable CDP at the global level, use the no CDP run command in global configuration mode. If CDP is disabled globally, individual interfaces cannot be enabled for CDP. On Cisco IOS Release 10.3 or higher, CDP is enabled by default on all supported interfaces to send and receive CDP information. However, on some interfaces, such as asynchronous interfaces, CDP is disabled by default. If CDP is disabled use the CDP enable command in interface configuration mode. To disable CDP on a specific interface after it has been enabled, use the no CDP enable command in interface configuration mode.
