You can set a global username, password, and enable password for all access points that are currently joined to the device and any that join in the future inherit as they join the device. If desired, you can override the global credentials and assign a unique username, password, and enable password for a specific access point.
After an access point joins the device, the access point enables console port security, and you are prompted for your username and password whenever you log into the access point’s console port. When you log in, you are in nonprivileged mode, and you must enter the enable password in order to use the privileged mode.
The global credentials that you configure on the device are retained across device and access point reboots. They are overwritten only if the access point joins a new device that is configured with a global username and password. If the new device is not configured with global credentials, the access point retains the global username and password configured for the first device.
You must track the credentials used by the access points. Otherwise, you might not be able to log into an access point’s console port. If you need to return the access points to the default Cisco/Cisco username and password, you must clear the device’s configuration and the access point’s configuration to return them to factory-default settings. To reset the default access point configuration, enter the ap name Cisco_AP mgmtuser username Cisco password Cisco command. Entering the command does not clear the static IP address of the access point. Once the access point rejoins a device, it adopts the default Cisco/Cisco username and password.
You can configure global authentication settings for all access points that are currently joined to the device and any that join in the future. If desired, you can override the global authentication settings and assign unique authentication settings for a specific access point.
This feature is supported on the following hardware:
All Cisco switches that support authentication.
Cisco Aironet 1140, 1260, 1310, 1520, 1600, 2600, 3500, and 3600 access points
The device name in the AP configuration is case sensitive. Therefore, make sure to configure the exact system name on the AP configuration. Failure to do this results in the AP fallback not working.
Cisco IOS access points are shipped from the factory with Cisco as the default enable password. This password allows users to log into the nonprivileged mode and enter the show and debug commands that pose a security threat to your network. You must change the default enable password to prevent unauthorized access and to enable users to enter configuration commands from the access point’s console port.
You can configure 802.1X authentication between a lightweight access point and a Cisco switch. The access point acts as an 802.1X supplicant and is authenticated by the switch where it uses EAP-FAST with anonymous PAC provisioning.

ap dot1x username user_name_value password 0 password_value Example: |
Configures the global authentication username and password for all access points that are currently joined to the device and any access points that join the device in the future. This command contains the following keywords and arguments:
|
||
| Step 4 |
end Example: |
Returns to privileged EXEC mode. Alternatively, you can also press Ctrl-Z to exit global configuration mode. |
||
| Step 5 |
ap name Cisco_AP dot1x-user username username_value password password_value Example: |
Overrides the global authentication settings and assigns a unique username and password to a specific access point. This command contains the following keywords and arguments:
The authentication settings that you enter in this command are retained across device and access point reboots and whenever the access point joins a new device. |
||
| Step 6 |
configure terminal Example: |
Enters global configuration mode. |
||
| Step 7 |
no ap dot1x username user_name_value password 0 password_value Example: |
Disables 802.1X authentication for all access points or for a specific access point.
|
||
| Step 8 |
end Example: |
Returns to privileged EXEC mode. Alternatively, you can also press Ctrl-Z to exit global configuration mode. |
