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
devices

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, 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

For example, to disable CDP on the switch:

Switch 4108GL(config) no cdp run

When CDP is disabled:

show cdp neighbors

displays an empty CDP Neighbors table

show cdp

displays

Global CDP information
Enable CDP : No

Note that the table will again list entries after the switch
recives new CDP packets from neighboring CDP devices.
