Enabling or disabling CDP operation on individual ports
In the factory-default configuration, the switch has all ports enabled to receive CDP packets. Disabling CDP on a port causes it to drop inbound CDP packets without recording their data in the CDP Neighbors table.
Syntax:
[no] cdp enable {< [e] port-list >}
Example:
To disable CDP on port A1:
switch(config)# no cdp enable a1
