Using the CLI to View Cisco Discovery Protocol Information
Use these commands to obtain information about CDP neighbors on the controller.
1. To see the status of CDP and to view CDP protocol information, enter this command:
show cdp
2. To see a list of all CDP neighbors on all interfaces, enter this command:
show cdp neighbors [detail]
The optional detail command provides detailed information for the controller’s CDP neighbors.
Note This command shows only the CDP neighbors of the controller. It does not show the CDP
neighbors of the controller’s associated access points. Additional commands are provided
below to show the list of CDP neighbors per access point.
3. To see all CDP entries in the database, enter this command:
show cdp entry all
4. To see CDP traffic information on a given port (for example, packets sent and received, CRC errors,
and so on), enter this command:
show cdp traffic
5. To see the CDP status for a specific access point, enter this command:
show ap cdp ap-name Cisco_AP
6. To see the CDP status for all access points that are connected to the controller, enter this command:
show ap cdp all
7. To see a list of all CDP neighbors for a specific access point, enter these commands:
show ap cdp neighbors ap-name Cisco_AP
show ap cdp neighbors detail Cisco_AP
Note The access point sends CDP neighbor information to the controller only when the
information changes.
