Enabling and Disabling CDP Operation
Enabling CDP operation (the default) on the switch causes the switch to add entries to its CDP Neighbors table for any CDP packets it receives from other neighboring CDP devices.
Disabling CDP operation clears the switch's CDP Neighbors table and causes the switch to drop inbound CDP packets from other devices without entering the data in the CDP Neighbors table.
Syntax:
[no] cdp run

(Default: Enabled)
Example:
To disable CDP read-only on the switch:
