Chapter 4 Configuring Controller Settings
Configuring the Cisco Discovery Protocol
The range is 10 to 255 seconds, and the default value is 180 seconds.
Step 4 Specify the highest CDP version supported on the controller by entering this command:
config cdp advertise {v1 | v2}
The default value is v1.
Step 5 Enable or disable CDP on all access points that are joined to the controller by entering the config ap cdp
{enable | disable} all command.
The config ap cdp disable all command disables CDP on all access points that are joined to the
controller and all access points that join in the future. CDP remains disabled on both current and future
access points even after the controller or access point reboots. To enable CDP, enter the config ap cdp
enable all command.
Note After you enable CDP on all access points joined to the controller, you may disable and then reenable
CDP on individual access points using the command in Step 6. After you disable CDP on all access
points joined to the controller, you may not enable and then disable CDP on individual access points.
Step 6 Enable or disable CDP on a specific access point by entering this command:
config ap cdp {enable | disable} Cisco_AP
Step 7 Configure CDP on a specific or all access points for a specific interface by entering this command:
config ap cdp {ethernet | radio} interface_number slot_id {enable | disable} {all | Cisco_AP}
Note When you use the config ap cdp command to configure CDP on radio interfaces, a warning message
appears indicating that the configuration is applicable only for mesh access points.
Step 8 Save your changes by entering this command:
save config
Using the CLI to View Cisco Discovery Protocol Information
To obtain information about CDP neighbors on the controller using the controller CLI, follow these
steps:
Step 1 See the status of CDP and to view CDP protocol information by entering this command:
show cdp
Step 2 See a list of all CDP neighbors on all interfaces by entering 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.
