Which Cisco IOS Cisco Discovery Protocol (CDP) command displays the IP address of the directly connected
Cisco devices?

A.
show cdp

B.
show cdp devices

C.
show cdp traffic

D.
show cdp neighbors detail

Explanation:
The show cdp neighbors detail command displays the IP address of the directly connected Cisco devices. CDP
is a Layer 2 (Data Link layer) protocol that finds information about neighboring network devices. CDP does not
use Network layer protocols to transmit information because it operates at the Data Link layer. For this reason,
IP addresses need not even be configured on the interfaces for CDP to function. The only requirement is that
the interfaces be enabled with the no shutdown command. An example of the output of the show cdp neighbors
detail command is as follows:

The show cdp devices command is incorrect because this is not a valid Cisco IOS command.
The show cdp command is incorrect because this command is used to view the global CDP information. It lists
the default update and holdtime timers, as in the following sample output:
Atlanta# show cdp
Global CDP information:Sending CDP packets every 60 seconds
Sending a holdtime value of 180 seconds
Sending CDPv2 advertisements is enabled
The show cdp traffic command is incorrect because this command displays traffic information between network
devices collected by the CDP, as in the following example:
Birmingham# show cdp traffic
Total packets output: 652, Input: 214
Hdr syntax: 0, Chksum error: 0, Encaps failed: 0
No memory: 0, Invalid: 0, Fragmented: 0
CDP version 1 advertisements output: 269, Input: 50
CDP version 2 advertisements output: 360, Input: 25
