Configuring CDP Operation

Enabling or Disabling CDP Operation on the Switch. Enabling CDP
operation (the default) on the switch causes the switch to:
Transmit CDP packets describing itself to other, neighboring CDP
I
devices
Add entries to its CDP Neighbors table for any CDP packets it receives
I
from other, neighboring CDP devices
Disabling CDP operation clears the switch's CDP Neighbors table, prevents
the switch from transmitting outbound CDP packets to advertise itself to
neighboring CDP devices, 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
Enables or disables CDP operation on the switch.
(Default: Enabled)
For example, to disable CDP on the switch:
HPswitch(config) no cdp run
