Using two power sources on the access point might cause the access point to shut down to protect internal components and might cause the switch to shut down the port to which the access point is connected. If your access point shuts down, you must remove all power and reconnect only a single power source.Follow these steps to connect the access point to the Ethernet LAN when you have an inline power source:Step 1 Connect a Category 5 Ethernet cable to the RJ-45 Ethernet connector labeled Ethernet on the access point (see Figure 2-9).Figure 2-9 Ethernet and Power Ports Step 2 Connect the other end of the Ethernet cable to one of the following:•A switch with inline power (see the “Connecting the Ethernet and Power Cables” section on page 2-13).•The end of a Cisco Aironet power injector labeled To AP/Bridge.

Using two power sources on the access point might cause the access point to shut down to protect internal components and might cause the switch to shut down the port to which the access point is connected. If your access point shuts down, you must remove all power and reconnect only a single power source.Follow these steps to connect the access point to an Ethernet LAN when you are using a local power source:Step 1 Connect a Category 5 Ethernet cable to the RJ-45 Ethernet connector labeled Ethernet on the access point (see Figure 2-9). Step 2 Connect the power module output connector to the access point’s 48-VDC power port (see Figure 2-9).Step 3 Plug the other end of the Ethernet cable into an unpowered Ethernet port on your LAN network.Step 4 Plug the other end of the power module into an approved 100- to 240-VAC outlet.For information on securing your access point, see the “Securing the Access Point” section on page 2-18.Powering Up the Access Point When power is applied to the access point, it begins a routine power-up sequence that you can monitor by observing the three LEDs on the end of the access point. After you observe all three LEDs turning green to indicate the starting of the IOS operating system, the Status LED blinks green signifying that IOS is operational. When in an operational status, the Ethernet LED is steady green when no traffic is being passed and dark during periods when traffic is being passed. The sequence takes about 1 minute to complete. Refer to Chapter 6, “Troubleshooting,” for LED descriptions.When the sequence is complete, you are ready to obtain the access point’s IP address and perform an initial configuration. Refer to Chapter 3, “Configuring the Access Point for the First Time.” for instructions on assigning basic settings to the access point.Caution Be careful when handling the access point; the bottom plate might be hot.Note If your access point is connected to in-line power, do not connect the power module to the access point. Using two power sources on the access point might cause the access point to shut down to protect internal components and might cause the switch to shut down the port to which the access point is connected. If your access point shuts down, you must remove all power and reconnect only a single power source.

3-9Cisco Aironet 1240AG Series Access Point Hardware Installation GuideOL-7293-01Chapter 3 Configuring the Access Point for the First TimeConfiguring Basic Security SettingsEnabling the Radio InterfacesIn Cisco IOS Release 12.3(7)JA, the access point radios are disabled by default, and there is no default SSID. You must create an SSID and enable the radios before the access point will allow wireless associations from other devices. These changes to the default configuration improve the security of newly installed access points. Refer to the “Configuring Basic Security Settings” section on page 3-9 for instructions on configuring the SSID.To enable the radio interfaces, follow these instructions:Step 1 Use your web-browser to access your access point.Step 2 When the Summary Status page displays, click Radio0-802.11B or Radio0-802.11G and the 2.4 GHz radio status page displays.Step 3 Click Settings and the radio settings page displays.Step 4 Click Enable in the Enable Radio field.Step 5 Click Apply.Step 6 Click Radio1-802.11A and the 5 GHz radio status page displays.Step 7 Repeat Steps 3 to 5.Step 8 Close your web-browser.Configuring Basic Security SettingsAfter you assign basic settings to your access point, you must configure security settings to prevent unauthorized access to your network. Because it is a radio device, the access point can communicate beyond the physical boundaries of your building. Just as you use the Express Setup page to assign basic settings, you can use the Express Security page to create unique SSIDs and assign one of four security types to them. For detail security information, refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points.

3-11Cisco Aironet 1240AG Series Access Point Hardware Installation GuideOL-7293-01Chapter 3 Configuring the Access Point for the First TimeConfiguring Basic Security SettingsUnderstanding Express Security SettingsWhen the access point configuration is at factory defaults, the first SSID that you create by using the Express Security page overwrites the default SSID (tsunami), which has no security settings. The SSIDs that you create appear in the SSID table at the bottom of the page. You can create up to 16 SSIDs on the access point.Note In Cisco IOS Release 12.3(7)JA, there is no default SSID. You must configure an SSID before client devices can associate to the access point.Using VLANsIf you use VLANs on your wireless LAN and assign SSIDs to VLANs, you can create multiple SSIDs by using any of the four security settings on the Express Security page. However, if you do not use VLANs on your wireless LAN, the security options that you can assign to SSIDs are limited because of the limited Express Security page options. Without VLANs, encryption settings (WEP and ciphers) apply to an interface, such as the radio, and you cannot use more than one encryption setting on an interface. For example, when you create an SSID with static WEP with VLANs disabled, you cannot create additional SSIDs with WPA authentication because they use different encryption settings. If you find that the security setting for an SSID conflicts with another SSID, you can delete one or more SSIDs to eliminate the conflict.If any VLANs are defined on the access point, the trunk port on the switch must be limited to allow only the VLANs defined on the access point.Express Security TypesTable 3-2 describes the four security types that you can assign to an SSID.Ta b l e 3 - 2 S e c u r i t y Ty p e s o n Express Security Setup PageSecurity Type Description Security Features EnabledNo Security This is the least secure option. You should use this option only for SSIDs used in a public space and assign it to a VLAN that restricts access to your network.None.Static WEP Key This option is more secure than no security. However, static WEP keys are vulnerable to attack. If you configure this setting, you should consider limiting association to the bridge based on MAC address (refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points).Mandatory WEP. Client devices cannot associate using this SSID without a WEP key that matches the bridge’s key.
3-12Cisco Aironet 1240AG Series Access Point Hardware Installation GuideOL-7293-01Chapter 3 Configuring the Access Point for the First TimeConfiguring Basic Security Settings28Express Security LimitationsBecause the Express Security page is designed for simple configuration of basic security, the options available are a subset of the bridge’s security capabilities. Keep these limitations in mind when using the Express Security page:•If the No VLAN option is selected, the static WEP key can be configured once. If you select Enable VLAN, the static WEP key should be disabled.•You cannot edit SSIDs. However, you can delete SSIDs and re-create them.•You cannot assign SSIDs to specific radio interfaces. The SSIDs that you create are enabled on all radio interfaces. To assign SSIDs to specific radio interfaces, use the Security SSID Manager page.•You cannot configure multiple authentication servers. To configure multiple authentication servers, use the Security Server Manager page.•You cannot configure multiple WEP keys. To configure multiple WEP keys, use the Security Encryption Manager page.•You cannot assign an SSID to a VLAN that is already configured on the bridge. To assign an SSID to an existing VLAN, use the Security SSID Manager page.•You cannot configure combinations of authentication types on the same SSID (for example, MAC address authentication and EAP authentication). To configure combinations of authentication types, use the Security SSID Manager page.Note For detailed information about security and security settings, refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points.EAP AuthenticationThis option enables 802.1x authentication (such as LEAP, PEAP, EAP-TLS, EAP-GTC, EAP-SIM, and others) and requires you to enter the IP address and shared secret for an authentication server on your network (server authentication port 1645). Because 802.1x authentication provides dynamic encryption keys, you do not need to enter a WEP key.Mandatory 802.1x authentication. Client devices that associate using this SSID must perform 802.1x authentication.WPA Wi-Fi Protected Access (WPA) permits wireless access to users authenticated against a database through the services of an authentication server, then encrypts their IP traffic with stronger algorithms than those used in WEP. As with EAP authentication, you must enter the IP address and shared secret for an authentication server on your network (server authentication port 1645).Mandatory WPA authentication. Client devices that associate using this SSID must be WPA-capable.Table 3-2 Security Types on Express Security Setup Page (continued)Security Type Description Security Features Enabled
3-13Cisco Aironet 1240AG Series Access Point Hardware Installation GuideOL-7293-01Chapter 3 Configuring the Access Point for the First TimeFinding the IP Address Using the CLIUsing the Express Security PageFollow these steps to create an SSID using the Express Security page:Step 1 Type the SSID in the SSID entry field. The SSID can contain up to 32 alphanumeric characters.Note These characters are not allowed in the SSID: ", /, ], +, tab, and a trailing space character. Step 2 To broadcast the SSID in the bridge beacon, check the Broadcast SSID in Beacon check box. When you broadcast the SSID, devices that do not specify an SSID can associate to the bridge. This is a useful option for an SSID used by guests or by client devices in a public space. If you do not broadcast the SSID, client devices cannot associate to the bridge unless their SSID matches this SSID. Only one SSID can be included in the bridge beacon.Step 3 (Optional) Check the Enable VLAN ID check box and enter a VLAN number (1 through 4095) to assign the SSID to a VLAN. You cannot assign an SSID to an existing VLAN.Step 4 (Optional) Check the Native VLAN check box to mark the VLAN as the native VLAN. Step 5 Select the security setting for the SSID. The settings are listed in order of robustness, from No Security to WPA, which is the most secure setting. •If you select Static WEP Key, choose the key number and encryption key size and enter the encryption key (10 hexidecimal characters for 40-bit keys or 26 hexidecimal characters for 128-bit keys).•If you select EAP Authentication or WPA, enter the IP address and shared secret for the authentication server on your network.Note If you do not use VLANs on your wireless LAN, the security options that you can assign to multiple SSIDs are limited. Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points for VLAN details.Step 6 Click Apply. The SSID appears in the SSID table at the bottom of the page.Finding the IP Address Using the CLIWhen you connect the access point to the wired LAN, the access point links to the network using a bridge virtual interface (BVI) that it creates automatically. Instead of tracking separate IP addresses for the access point’s Ethernet and radio ports, the network uses the BVI.To find the IP address of your access point using the console port, you can use the Cisco IOS CLI show ip interface brief bvi1 from the privileged EXEC mode. For additional information on the CLI, refer to the“Using the Command-Line Interface” section on page 5-1.

This chapter contains these sections:•Cisco IOS Command Modes, page 5-2•Getting Help, page 5-3•Abbreviating Commands, page 5-3•Using no and default Forms of Commands, page 5-4•Understanding CLI Messages, page 5-4•Using Command History, page 5-4•Using Editing Features, page 5-6•Searching and Filtering Output of show and more Commands, page 5-8•Accessing the CLI, page 5-9
5-2Cisco Aironet 1240AG Series Access Point Hardware Installation GuideOL-7293-01Chapter 5 Using the Command-Line InterfaceCisco IOS Command ModesCisco IOS Command ModesThe Cisco IOS user interface is divided into many different modes. The commands available to you depend on the mode you are currently using. Enter a question mark (?) at the system prompt to obtain a list of commands available for each command mode. Refer to the Cisco IOS Command Reference for Cisco Aironet Access Points and Bridges for a list of the supported Cisco IOS commands.When you start a session on the access point, you begin in user mode, often called user EXEC mode. Only a limited subset of the commands are available in user EXEC mode. For example, most of the user EXEC commands are one-time commands, such as show commands, which show the current configuration status, and clear commands, which clear counters or interfaces. The user EXEC commands are not saved when the access point reboots.To have access to all commands, you must enter privileged EXEC mode. Normally, you must enter a password to enter privileged EXEC mode. You must enter privileged EXEC mode before you can enter the global configuration mode. Using the configuration modes (global, interface, and line), you can make changes to the running configuration. If you save the configuration, these commands are stored and used when the access point reboots. To access the various configuration modes, you must start at global configuration mode.Table 5-1 describes the main command modes, how to access each one, the prompt you see in that mode, how to exit the mode, and how to use the mode. The examples in the table use the host name ap.Table 5-1 Command Mode SummaryMode Access Method Prompt Exit Method Using This ModeUser EXEC Begin a session with your access point.ap> Enter logout or quit. Use this mode to:•Change terminal settings•Perform basic tests•Display system informationPrivileged EXEC While in user EXEC mode, enter the enable command.ap# Enter disable to exit. Use this mode to verify commands. Use a password to protect access to this mode.Global configuration While in privileged EXEC mode, enter the configure command.ap(config)# To exit to privileged EXEC mode, enter exit or end, or press Ctrl-Z.Use this mode to configure parameters that apply to the entire access point.Interface configurationWhile in global configuration mode, enter the interface command (with a specific interface).ap(config-if)# To exit to global configuration mode, enter exit. To return to privileged EXEC mode, press Ctrl-Z or enter end.Use this mode to configure parameters for the Ethernet and radio interfaces. The 2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.

You can also obtain a list of associated keywords and arguments for any command, as shown in Table 5-2.Abbreviating CommandsYou have to enter only enough characters for the access point to recognize the command as unique. If you do not enter enough characters, the access point indicate an error (% Unknown command). This example shows how to enter the show configuration privileged EXEC command:ap# show confTable 5-2 Help SummaryCommand Purposehelp Obtains a brief description of the help system in any command mode.abbreviated-command-entry?Obtains a list of commands that begin with a particular character string.For example:ap# di?dir disable disconnect abbreviated-command-entry<Tab> Completes a partial command name.

5-4Cisco Aironet 1240AG Series Access Point Hardware Installation GuideOL-7293-01Chapter 5 Using the Command-Line InterfaceUsing no and default Forms of CommandsUsing no and default Forms of CommandsMost configuration commands also have a no form. In general, use the no form to disable a feature or function or reverse the action of a command. For example, the no shutdown interface configuration command reverses the shutdown of an interface. Use the command without the keyword no to re-enable a disabled feature or to enable a feature that is disabled by default. Configuration commands can also have a default form. The default form of a command returns the command setting to its default. Most commands are disabled by default, so the default form is the same as the no form. However, some commands are enabled by default and have variables set to certain default values. In these cases, the default command enables the command and sets variables to their default values.Understanding CLI MessagesTable 5-3 lists some error messages that you might encounter while using the CLI to configure your access point.Using Command HistoryThe IOS provides a history or record of commands that you have entered. This feature is particularly useful for recalling long or complex commands or entries, including access lists. You can customize the command history feature to suit your needs as described in these sections:•Changing the Command History Buffer Size, page 5-5•Recalling Commands, page 5-5•Disabling the Command History Feature, page 5-5Table 5-3 Common CLI Error MessagesError Message Meaning How to Get Help% Ambiguous command: "show con"You did not enter enough characters for your access point to recognize the command.Re-enter the command followed by a question mark (?) with a space between the command and the question mark.The possible keywords that you can enter with the command are displayed.% Incomplete command.

6-4Cisco Aironet 1240AG Series Access Point Hardware Installation GuideOL-7293-01Chapter 6 TroubleshootingChecking Basic SettingsDefault IP Address BehaviorWhen you connect a 1240 series access point running Cisco IOS Release 12.3(7)JA software with a default configuration to your LAN, the access point requests an IP address from your DHCP server and, if it does not receive an IP address, continues to send requests indefinitely.Enabling the Radio InterfacesIn Cisco IOS Release 12.3(7)JA, the access point radios are disabled by default, and there is no default SSID. You must create an SSID and enable the radios before the access point will allow wireless associations from other devices. These changes to the default configuration improve the security of newly installed access points. Refer to the “Configuring Basic Security Settings” section on page 3-9 for instructions on configuring the SSID.To enable the radio interfaces, follow these instructions:Step 1 Use your web-browser to access your access point.Step 2 When the Summary Status page displays, click Network Interfaces > Radio0-802.11G and the radio status page displays.Step 3 Click Settings and the radio settings page displays.Step 4 Click Enable in the Enable Radio field.Step 5 Click Apply.Step 6 Click Radio1-802.11A and the radio status page displays.Step 7 Repeat Steps 3 to 5.Step 8 Close your web-browser.SSIDWireless clients attempting to associate with the access point must use the same SSID as the access point. If a client device’s SSID does not match the SSID of an access point in radio range, the client device will not associate. Note In Cisco IOS Release 12.3(7)JA, there is no default SSID. You must configure an SSID before client devices can associate to the access point.WEP KeysThe WEP key you use to transmit data must be set up exactly the same on your access point and any wireless devices with which it associates. For example, if you set WEP Key 3 on your client adapter to 0987654321 and select it as the transmit key, you must also set WEP Key 3 on the access point to exactly the same value. The access point does not need to use Key 3 as its transmit key, however.Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points for instructions on setting the access point’s WEP keys.
6-5Cisco Aironet 1240AG Series Access Point Hardware Installation GuideOL-7293-01Chapter 6 TroubleshootingLow Power ConditionSecurity SettingsWireless clients attempting to authenticate with your access point must support the same security options configured in the access point, such as EAP or LEAP, MAC address authentication, Message Integrity Check (MIC), WEP key hashing, and 802.1X protocol versions.If a wireless client is unable to authenticate with your access point, contact the system administrator for proper security settings in the client adapter and for the client adapter driver and firmware versions that are compatible with the access point settings.Note The access point MAC address that displays on the Status page in the Aironet Client Utility (ACU) is the MAC address for the access point radio. The MAC address for the access point Ethernet port is printed on the label on the back of the access point.Low Power ConditionWarningThis product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source or an IEC60950 compliant limited power source. Statement 353The access point can be powered from the 48-VDC power module or from an in-line power source. The access point supports the IEEE 802.3af power standard, Cisco Pre-Standard PoE protocol, and Cisco Intelligent Power Management for in-line power sources. For full operation, the access point requires 12.95 W of power. The power module and Cisco Aironet power injectors are capable of supplying the required power for full operation, but some inline power sources are not capable of supplying 12.95 W. Also, some high-power inline power sources, might not be able to provide 12.95 W of power to all ports at the same time.Note An 802.3af compliant switch (Cisco or non-Cisco) is capable of supplying sufficient power for full operation.Note If your access point is connected to in-line power, do not connect the power module to the access point. Using two power sources on the access point might cause the access point to shut down to protect internal components and might cause the switch to shut down the port to which the access point is connected. If your access point shuts down, you must remove all power and reconnect only a single power source.On power up, the access point is placed into low power mode (both radios are disabled), Cisco IOS software loads and runs, and power negotiation determines if sufficient power is available. If there is sufficient power then the radios are turned on; otherwise, the access point remains in low power mode with the radios disabled to prevent a possible over-current condition. In low power mode, the access point activates the Status LED low power error indication, displays a low power message on the browser and serial interfaces, and creates an event log entry (see the “Checking the Access Point LEDs” section on page 6-2 and “Inline Power Status Messages” section on page 6-6).
6-6Cisco Aironet 1240AG Series Access Point Hardware Installation GuideOL-7293-01Chapter 6 TroubleshootingLow Power ConditionIntelligent Power ManagementThe access point requires 12.95 W of power for full power operation with both radios, but only needs6.3 W of power when operating in low power mode with both radios disabled. To help avoid an over-current condition with low power sources and to optimize power usage on Cisco switches, Cisco developed Intelligent Power Management, which uses Cisco Discovery Protocol (CDP) to allow powered devices (such as your access point) to negotiate with a Cisco switch for sufficient power. The access point supports Intelligent Power Management and as a result of the power negotiations, the access point will either enter full power mode or remain in low power mode with the radios disabled. Note Independent of the power negotiations, the access point hardware also uses the 802.3af classification scheme to indicate the power required from the power source. However, the power source cannot report the power available to the access point unless the power source also supports Intelligent Power Management.Some Cisco switches that are capable of supplying sufficient power require a software upgrade to support Intelligent Power Management. If the software upgrade is not desired, you can configure the access point to operate in pre-standard compatibility mode and the access point automatically enters full power mode if these Cisco switches are detected in the received CDP ID field. When the access point determines that sufficient power is not available for full power operation, an error message is logged and the Status LED turns amber to indicate low power mode (see the “Checking the Access Point LEDs” section on page 6-2 and the “Inline Power Status Messages” section on page 6-6).Tip If your switch is capable of supplying sufficient power for full operation but the access point remains in low-power mode, your access point or your switch (or both) might be misconfigured (see Table 6-2 and Table 6-3).If your inline power source is not able to supply sufficient power for full operation, you should consider these options:•Upgrade to a higher-powered switch •Use a Cisco Aironet power injector on the switch port•Use the 48-VDC power module to locally power the access pointInline Power Status MessagesThese messages are logged on the console port by the access point to report the power condition:•%CDP_PD-4-POWER_OK: Full Power - AC_ADAPTOR inline power source—This message indicates the access point is using the power module and can support full-power operation.•%CDP_PD-4-POWER_OK: Full Power - NEGOTIATED inline power source—This message indicates the access point is operating at full power and has successfully negotiated for 12.95 W of power from a Cisco switch supporting Cisco Intelligent Power Management.•%CDP_PD-4-POWER_OK: Full Power - HIGH_POWER_CLASSIC inline power source—This message indicates the access point is operating at full power because it has been configured for pre-standard compatibility mode and has detected a Cisco switch that does not support Intelligent Power Management but is able to supply sufficient power to the access point.

The <xxxx.xxxx.xxxx> indicates the MAC address of the switch port.Note You need to upgrade the software on the Cisco switch to support Intelligent Power Management or configure the access point for pre-standard compatibility.Configuring Power Using the CLIIntelligent Power Management support is dependent on the version of software resident in the Cisco switch that is providing power to the access point. Each Cisco switch should be upgraded to support Intelligent Power Management. Until the software is upgraded, you can configure the access point to operate with older switch software using the following Cisco IOS CLI command:[no] power inline negotiation {prestandard source | injector H.H.H}(where H.H.H is the MAC address of the switch port to which the access point is connected)You can use this Cisco IOS CLI command to inform the access point of the following:•The Cisco switch does not support Intelligent Power Management but should be able to supply sufficient power.•A power injector is being used to supply sufficient power and the Cisco switch does not support Intelligent Power Management. Refer to Table 6-2 for information on when to use this special Cisco IOS command and the corresponding Cisco switch power command.Caution If the access point receives power through PoE, the output current of the power sourcing equipment (PSE) cannot exceed 400 mA per port. The power source must comply with IEEE802.3af or IEC60950 for limited power sources.Note After completing your configuration changes, you must remove the serial console cable from the access point.Table 6-2 Using Cisco IOS CommandsPower SourceCisco IOS CommandsAccess Point Cisco SwitchAC power module None required power inline neverCisco switch that supports Intelligent Power Management1no power inline negotiation prestandard sourceno power inline negotiation injectorpower inline auto Cisco switch that does not support Intelligent Power Management1power inline negotiation prestandard sourceno power inline negotiation injectorpower inline autoPower injector2 used with a Cisco switch that supports Intelligent Power Management1no power inline negotiation prestandard sourceno power inline negotiation injectorpower inline never3
