IT Support Dude The LWAPP upgrade tool does not release Windows operating system memory resources when the upgrade process is complete. Memory resources are released only after you exit the upgrade tool. If you upgrade several batches of access points, you must exit the tool in between batches to release memory resources. If you do not exit the tool in between batches, performance of the upgrade station quickly degrades because of excessive memory consumption.

Factory installed certificates are referenced by the term MIC, which is an acronym for Manufacturing Installed Certificate. Cisco Aironet access points shipped before July 18, , do not have MIC, so these access points create a self-signed certificate when upgraded to operate in lightweight mode. Controllers are programmed to accept self-signed certificates for authentication of specific access points. This is an example of a detailed log from the upgrade tool:. The upgrade tool adds an entry to the controller authentication list with the MAC address of the AP and public key-hash.

The controller needs the public key-hash in order to validate the SSC signature. If the entry has not been added to the controller, check the output CSV file. There should be entries for each AP. If you find the entry, import that file into the controller. If you use the controller command-line interface CLI with use of the config auth-list command or the switch web, you must import one file at a time. The next section discusses some of the commonly seen issues in the upgrade operation and the steps to resolve these issues.

The AP does not join the controller. The Solutions section of this document provides the causes in order of probability. This is the output of the debug lwapp events enable command:. Check for IP connectivity between the AP network and the controller. If the controller and the AP reside in the same subnet, ensure that they are properly interconnected. If they reside in different subnets, ensure that a router is used in between them and routing is properly enabled between the two subnets.

If option 43 is used as the discovery option, ensure that it is properly configured on the DHCP server. Note: Remember that when you convert statically-addressed APs, the only Layer 3 discovery mechanism that works is the DNS because the static address is preserved during the upgrade. On the AP, you can issue the debug lwapp client events command and the debug ip udp command in order to receive enough information to determine exactly what occurs.

Note: In some situations, there can be more than one controller and the AP might try to join a different controller on the basis of the LWAPP discovery state machine and algorithms. This situation might occur because of the default dynamic AP load balancing that the controller performs. This situation can be worth examination. If necessary, issue the lwapp ap controller ip address A.

Note: This CLI command can be used on an AP that has never registered to a controller, or on an AP that had its default enable password changed while joined to a previous controller. These debug commands show the debug of certificate messages that are passed between the AP and the WLC. The commands clearly show a message that the certificate is rejected as outside the validity interval. In this output, notice the highlighted information. This information clearly shows that the controller time is outside the certificate validity interval of the AP.

Therefore, the AP cannot register with the controller. Certificates installed in the AP have a predefined validity interval. The controller time should be set in such a way that it is within the certificate validity interval of the AP.

The entire output is not listed as there can be many validity intervals associated with the output of this command. This is the actual certificate validity interval to be considered. Issue the show time command from the controller CLI in order to verify that the date and time set on your controller falls within this validity interval.

If the controller time is above or below this certificate validity interval, then change the controller time to fall within this interval. This key-hash can be obtained from the output of the debug pm pki enable command. See Cause 4 for information on getting the key-hash value. This command shows the actual public key-hash.

Check the current software version of the AP. On the main page, click on the System Software menu from the left hand side. Leave the name as it was when you downloaded the file from cisco. Click the Upgrade button. A status window similar to the one shown in Figure 2 appears. You can download a new image file and choose to replace the current image or keep the current image.

You can work with the access point from the other image in the flash. For image name , specify the Cisco IOS filename that you plan to use to upgrade the access point. As mentioned earlier, do not change the name of the Cisco IOS file. Leave it as the default. You find these logs during the successful file transfer:.

If there is not enough space to install the new image and keep the current running image, the download process stops, and an error message is displayed. On the TFTP server, check to see if you receive logs about this file transfer. Once the new image is downloaded, the access point automatically reloads.

At this time, the connection to the access point is lost. Login to the AP again. If you use the CLI, you can check this with the show version command. This section contains these example configurations:. Example: No Security for Radio 2. Example: EAP Authentication. Example: WPA2 for Radio 2. Depending on your power source, you might need to enter the power source type in the access point configuration. If you use the AC power adapter to provide power access point, you do not need to adjust the access point configuration.

If you use a switch to provide Power over Ethernet PoE to the , , , , , and access point, and the switch supports the IEEE If you use a power injector to provide power to the , , , , , or access point, select Power Injector on the System Software: System Configuration page and enter the MAC address of the switch port to which the access point is connected.

When enabled, the dot11 extension power native shifts the power tables the radio uses from the IEEE The Native Power tables were designed specifically to configure powers as low as -1dBm for Cisco Aironet radios that support these levels. The Cisco Aironet Series access points requires 20W of power for optimum performance of This allows you to configure one radio to operate using This allows full functionality under Once you upgrade to a powering solution that provides 20W of power to the access point, you can configure the second radio so that both radios are fully functional with 2x3 multiple input multiple output MIMO technology.

Certain radio configurations may require more power than can be provided by the inline power source. When insufficient inline power is available, you can select several options based upon your access point radio configuration as shown in Table Maximum transmit power will vary by channel and according to individual country regulations.

Refer to the product documentation for specific details. It is designed to provide high throughput and operate in the 5 GHz band. The Shutting down the However the channel widths can be independently configured with the restriction that it should be above the channel width configured on Please see Table for more details on the supported channel width combinations. Table Supported Channel Width Combinations. Off channel scanning or transmissions are not supported.

The , , and Please refer to the below table. Tip Radio configurations such as 4x imply 4 transmitters and 4 receivers capable of 3 spatial streams. If the AP is running on reduced power, under Home:Summary Status, the following warning is displayed:. Due to insufficient inline power.

Upgrade inline power source or install power injector. All access points except outdoor mesh products can be powered over Ethernet. Access points with two radios powered over Ethernet are fully functional and support all the features.

See Table for the various power management options available. This is the power required at the PSE, which is either a switch or an injector. You cannot configure power levels independently for When you connect the wireless device to the wired LAN, the wireless device links to the network using a bridge virtual interface BVI that it creates automatically. Note If you are connected to the wireless device using a Telnet session, you lose your connection to the wireless device when you assign a new IP address to the BVI.

If you need to continue configuring the wireless device using Telnet, use the new IP address to open another Telnet session to the wireless device. Follow these steps to access the CLI by using a Telnet session. Check your PC operating instructions for detailed instructions for your operating system. Note In Windows , the Telnet window does not contain drop-down lists. To start the Telnet session in Windows , type open followed by the wireless device IP address.

First, access points can be placed in public places, inviting the possibility that they could be unplugged and their network connection used by an outsider. Second, when a repeater access point is incorporated into a wireless network, the repeater access point must authenticate to the root access point in the same way as a client does.

You can complete the phases in any order, but they must be completed before the supplicant becomes operational. Beginning in privileged EXEC mode, follow these steps to create an Creates a dot1x credentials profile and enters the dot1x credentials configuration submode.

Optional —Enter the anonymous identity to be used. Optional —Enter a description for the credentials profile. Enter an unencrypted password for the credentials. Hidden passwords are used when applying a previously saved configuration. Note Unencrypted and clear text are the same. You can enter a 0 followed by the clear text password, or omit the 0 and enter the clear text password. Optional Save your entries in the configuration file. Use the no form of the dot1x credentials command to negate a parameter.

The following example creates a credentials profile named test with the username Cisco and a the unencrypted password Cisco:. Credential profiles are applied to an interface or an SSID in the same way. Beginning in the privileged EXEC mode, follow these steps to apply the credentials to the access point wired port:. Enter the interface configuration mode for the access point Gigabit Ethernet port.

Note You can also use interface fa0 to enter the Gigabit Ethernet configuration mode. Enter the name of a previously created credentials profile. The following example applies the credentials profile test to the access point gigabit Ethernet port:. If you have a repeater access point in your wireless network and are using the Enter the The SSID can consist of up to 32 alphanumeric characters.

SSIDs are case sensitive. Note The first character cannot contain the! Enter the name of a preconfigured credentials profile. The following example applys the credentials profile test to the ssid testap1 on a repeater access point. IPv6 is the latest Internet protocol for IPv, developed to provide an extremely large number of addresses. It uses bit addresses instead of the 32 bit addresses that are used in IPv4.

As deployments in wireless networks use greater number of IP wireless devices and smart phones, IPv6 with its bit address format can support 3. IPv6 addresses are represented as a series of bit hexadecimal fields separated by colons : in the format: x:x:x:x:x:x:x:x. Aggregatable global unicast addresses are globally routable and reachable on the IPv6 portion of the Internet.

These global addresses are identified by the format prefix of The interface identifier is in the modified EUI format. Table lists the IPv6 address types and formats. Table IPv6 Address Formats. Beginning in privileged EXEC mode, use these commands to enable tie ipv6 address. A link-local address, based on the Modified EUI interface ID, is automatically generated for the interface when stateless autoconfiguration is enabled.

Beginning in privileged EXEC mode, use the following command to enable stateless autoconfiguration:. Beginning in privileged EXEC mode, use the following command to configure a link local addreess without assigning any other IPv6 addressesto the interface:. Beginning in privileged EXEC mode, use the following command to assign a site-local or global address to the interface:. The DHCPv6 client obtains configuration parameters from a server either through a rapid two-message exchange solicit, reply , or through a normal four-message exchange solicit, advertise, request, reply.

By default, the four-message exchange is used. When the rapid-commit option is enabled by both client and server, the two-message exchange is used. Stateful addressing uses a DHCP server. Beginning in privileged EXEC mode, use this command to configure stateful addressing:. Beginning in privileged EXEC mode, use this command to configure stateless addressing:.

The IPv6 neighbor discovery process uses ICMP messages and solicited-node multicast addresses to determine the link-layer address of a neighbor on the same network. This command is available only on bridge group virtual interface BVI. Sets the interval between IPv6 neighbor solicitation retransmissions on an interface. Sets the amount of time that a remote IPv6 node is reachable. Configures the number of consecutive neighbor solicitation messages sent when duplicate address detection is performed on the unicast IPv6 addresses.

Configures the interval between IPv6 neighbor solicit transmissions for duplicate address detection. Configures a default route to the Neighbor Discovery-derived default router. Configures router solicitation message to solicit a router advertisement to eliminate any delay in waiting for the next periodic router advertisement. Configures the length of time before the IPv6 neighbor discovery cache entry expires.

Configures a neighbor discovery cache limit on a specified interface. Configures neighbor discovery to glean an entry from an unsolicited neighbor advertisement. Configures IPv6 neighbor discovery non-stop forwarding. You can specify the covergence time in seconds 10 to seconds , suppress duplicate address detection DAD , or set the number of resolutions to use with non-stop forwarding NSF. Configures the number of neighbor unreachability detection NUD resends, and set a limit to the number of unresolved resends.

Configures a limit to the number of data packets in queue awaiting neighbor discovery ND resolution. Inserts Neighbor Discovery-learned routes into the routing table with "ND" status and enables ND autoconfiguration behavior. IPv6 access lists ACL are used to filter traffic and restrict access to the router.

IPv6 prefix lists are used to filter routing protocol updates. Beginning in privileged EXEC mode, use these commands to to configure the access list globally and assign it to interface:. Table IPv6 Access List configuration commands. Beginning in privileged EXEC mode, use these commands to assign the globally configured ACL to the outbound and inbound traffic on layer3 interface:.

Cisco IOS Release Link-local is not used for registration. Each CDP enabled device sends information about itself to its immediate neighbor. As part of native IPv6, the access point sends its IPv6 address as well as part of the address TLV in the cdp message; it also parses the IPv6 address information it gets from the neighboring switch.

RA filtering increases the security of the IPv6 network by dropping RAs coming from wireless clients. RA filtering prevents misconfigured or malicious IPv6 clients from connecting to the network, often with a high priority that takes precedence over legitimate IPv6 routers. In all cases, the IPv6 RA is dropped at some point, protecting other wireless devices and upstream wired network from malicious or misconfigured IPv6 devices. However, RA filtering is not supported in the uplink direction.

If the Autoconfig feaure is enabled, the AP downloads a configuration information file from the server at a pre-configured time and applies this configuration. The next configuration download is also scheduled along with this. Note The AP does not apply a configuration if it is the same as the last downloaded configuration.

Step 1 Prepare a Configuration Information File. Step 2 Enable environmental variables. The configuration information file is an XML file, containing the following information:. The configuration information file has the following format:.

The xml tags used in the configuration information file are described below. A random number of seconds between 0 to this value is added to the start time, to randomize the time when next information file is downloaded. After you have the configuration information file ready and hosted on the SCP server, you need to configure the following environmental variables.

Name of the configuration information file to be fetched from the SCP server. You can configure the environmental variables by using the following command in global configuration mode:. For example:. After setting the environmental variables, you need to schedule the download of the configuration information file from the SCP server. Follow these steps:.

Step 3 For instances where the download of the configuration information file from the SCP server fails, you can set a time interval after which the AP retries to download it again. After every failed download, the retry interval doubles, but the retires stop the interval when becomes larger than MAX.

To know the Autoconfig status, use the show dot11 autoconfig status command. You can use the following debugging commands as required:. Skip to content Skip to search Skip to footer. Book Contents Book Contents. Find Matches in This Book. Log in to Save Content. Updated: October 30, Configuring the Access Point for the First Time. Before You Start Before you install the wireless device, make sure you are using a computer connected to the same network as the wireless device, and obtain the following information from your network administrator: A system name for the wireless device The case-sensitive wireless service set identifier SSID for your radio network If not connected to a DHCP server, a unique IP address for the wireless device such as The MAC address can be found on the label on the bottom of the access point such as c.

Resetting the Device to Default Settings If you need to start over during the initial setup process, you can reset the access point to factory default settings. Caution You should never delete any of the system files prior to resetting defaults or reloading software. Caution Do not interrupt the boot process to avoid damaging the configuration file. You can also see the following CLI message when the load process has finished: Line protocal on Interface Dot11Radio0, changed state to up.

Follow the steps in the appropriate section to connect to the device console port: — Connecting to the , , , , , and Series Access Points Locally. Connecting to the , , , , , and Series Access Points Locally If you need to configure the access point locally without connecting the access point to a wired LAN , you can connect a PC to its console port using a DB-9 to RJ serial cable.

Connecting to the Series Access Point Locally If you need to configure the access point locally without connecting to a wired LAN , you can connect a PC to the Ethernet port on the long-reach power injector using a Category 5 Ethernet cable. Assigning Basic Settings After you determine or assign the wireless device IP address, you can browse to the wireless device Express Setup page and perform an initial configuration: Step 1 Open your Internet browser.
