Figure 15-24. Example of CDP Neighbors Table Listing
Lists the CDP device connected to the specified port.
(Allows only one port at a time.) Using detail provides
a longer list of details on the CDP device the switch
detects on the specified port.
[detail [ [e] port-num ] ]
Provides a list of the details for all of the CDP devices
the switch detects. Using port-num produces a list of
details for the selected port.
Figure 15-24 lists CDP devices that the switch has detected by receiving their
CDP packets.
Enabling 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. 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
Enables or disables CDP read-only operation on the switch.
(Default: Enabled)
For example, to disable read-only CDP on the switch:
ProCurve(config)# no cdp run
When CDP is disabled:
■ show cdp neighbors
Configuring for Network Management Applications
displays an empty CDP Neighbors table
