Disabling the Mode Button Chapter 5 Administering the Access Point Disabling the Mode Button You can disable the mode button on access points having a console port by using the [no] boot mode-button command. This command prevents password recovery and is used to prevent unauthorized users from gaining access to the access point CLI. Caution This command disables password recovery. If you lose the privileged EXEC mode password for the access point after entering this command, you will need to contact the Cisco Technical Assistance Center (TAC) to regain access to the access point CLI. The mode button is enabled by default. Beginning in the privilege EXEC mode, follow these steps to disable the access point’s mode button. Command Purpose Step 1 configure terminal Enter global configuration mode. Step 2 no boot mode-button Disables the access point’s mode button. Step 3 end Note It is not necessary to save the configuration. You can check the status of the mode-button by executing the show boot or show boot mode-button commands in the privileged EXEC mode. The status does not appear in the running configuration. The following shows a typical response to the show boot and show boot mode-button commands: ap#show boot BOOT path-list: flash:/c1200-k9w7-mx-v123_7_ja.20050430/c1200-k9w7-mx.v123_7_ja.20050430 Config file: flash:/config.txt Private Config file: flash:/private-config Enable Break: no Manual boot:no Mode button:on Enable IOS break: no HELPER path-list: NVRAM/Config file buffer size: 32768 ap#show boot mode-button on ap# Note As long as the privileged EXEC password is known, you can restore the mode button to normal operation using the boot mode-button command. 5-2 Cisco IOS Software Configuration Guide for Cisco Aironet Access Points OL-8191-01
Chapter 5 Administering the Access Point Preventing Unauthorized Access to Your Access Point Preventing Unauthorized Access to Your Access Point You can prevent unauthorized users from reconfiguring the wireless device and viewing configuration information. Typically, you want network administrators to have access to the wireless device while you restrict access to users who connect through a terminal or workstation from within the local network. To prevent unauthorized access to the wireless device, you should configure one of these security features: • Username and password pairs, which are locally stored on the wireless device. These pairs authenticate each user before that user can access the wireless device. You can also assign a specific privilege level (read only or read/write) to each username and password pair. For more information, see the “Configuring Username and Password Pairs” section on page 5-7. The default username is Cisco, and the default password is Cisco. Usernames and passwords are case-sensitive. Note Characters TAB, ?, $, +, and [ are invalid characters for passwords. • Username and password pairs stored centrally in a database on a security server. For more information, see the “Controlling Access Point Access with RADIUS” section on page 5-9. Protecting Access to Privileged EXEC Commands A simple way of providing terminal access control in your network is to use passwords and assign privilege levels. Password protection restricts access to a network or network device. Privilege levels define what commands users can issue after they have logged into a network device. Note For complete syntax and usage information for the commands used in this section, refer to the Cisco IOS Security Command Reference for Release 12.3. This section describes how to control access to the configuration file and privileged EXEC commands. It contains this configuration information: • Default Password and Privilege Level Configuration, page 5-4 • Setting or Changing a Static Enable Password, page 5-4 • Protecting Enable and Enable Secret Passwords with Encryption, page 5-6 • Configuring Username and Password Pairs, page 5-7 • Configuring Multiple Privilege Levels, page 5-8 OL-8191-01 Cisco IOS Software Configuration Guide for Cisco Aironet Access Points 5-3
