Download the image from cisco. The words a little confusing here as you are technically uploading a file to the controller but in the WLC world you download a file to the controller!? Once the image has downloaded to the primay and been extracted the controller will upload the file to the standby controller. SSH to your controller and issue the command show boot This is before.

SSH into the controller and issue the command config ap image predownload primary all. This will push the primary image 8. To verify the controller will boot from the primary image issue the command config boot primary. Before doing that just verify that the Redundancy is operational with the command show redundancy summary. To minimise downtime even more you can add the reset-aps keyword at the end of the command. At this point I would start to ping the management address of the controller to see when it comes back online.

For critical environments where you are local to the controllers you can monitor the process on the console. Hi, Just want to say thanks for your step through of the process. So thanks again! Good clear process, Thanks for the how too. It is most helpful. Sometimes it is easy to get lost in the documentation, and it takes a little longer to locate what is needed. This info is a great help. Great how-To document!

Do you have the procedure to Upgrade Software on Cisco in a primary and secondary redundancy configuration? When you issue that command the WLC will reboot in 2 minutes and 10 seconds. When I went to preload the AP they failed. What can I look at to solve the issue? Jumping from 7.

Thanks for the information! Quick question, I just wanted to make sure that I can prep everything before my maintenance window Download the image to the controller, pre-download the image to all the APs without any outages. Then reload during the maintenance window. This this correct?

The access points must remain powered, and the controller must not be reset during this time. You can predownload the AP image. This feature allows you to download the upgrade image to the controller, and then download the image to the access points while the network is still up.

A new CLI allows you to specify the boot image for both devices and to reset the access points when the controller resets. Note : Verify that your APs are compatible with the software you are planning to upgrade to to avoid loosing APs during the upgrade. Note : It is highly recommended to back up the configuration on the Wireless LAN controller before you perform the upgrade.

For this reason, it is recommended that you use a console port connection in order to check the state of the controller during the upgrade process and expedite any recovery procedures, if necessary. Make sure that the FTP server is reachable from the controller, and make sure the upgrade file resides in a directory of the FTP server. It is best to complete this procedure via the console port, but you can also SSH or Telnet if enabled to the controller's management IP address in order to complete the procedure.

The use of SSH or Telnet results in the loss of connectivity with the controller during the reboot process following the image download. Therefore, console access should be available in order to expedite troubleshooting and recovery of the controller if the upgrade fails. Log in to the controller and issue the show sysinfo command in order to verify the current software that runs on the controller.

This is sample output of the show sysinfo command, which shows that the controller runs 8. Issue the transfer download mode ftp command in order to define the mode of file transfer. Issue the transfer download filename filename command in order to specify the name of the image. Issue the transfer download start command in order to initiate the upgrade process. Reboot the controller after the upgrade process is complete in order for the new code to take effect.

Issue the reset system command, and enter y or yes in response to the question "Would you like to save them now? The configuration is not kept when you downgrade versions of controller code. Controllers can be upgraded from one release to another. Should you require a downgrade from one release to another, you possibly cannot use the higher release configuration. The workaround is to reload the previous controller configuration files that were saved on the backup server or reconfigure the controller.

Manually upgrading your devices to the latest software version can be error prone and time consuming. Cisco Prime Infrastructure simplifies the version management and routine deployment of software updates to your devices by helping you plan, schedule, download, and monitor software image updates.

You can also view software image details, view recommended software images, and delete software images. The software image management page provides a consolidated view of the various aspects of image management such as software image management lifecycle widget, software image summary, and job details.

Prime Infrastructure stores all of the software images for the devices in your network. The images are stored according to the image type and version. A software upgrade on the active controller ensures the upgrade of the standby-hot controller. An in-service upgrade is not supported. Therefore, you should plan your network downtime before you upgrade the controllers in an HA environment. Rebooting the active controller after a software upgrade also reboots the standby-hot controller.

We recommend that both active and standby-hot controllers have the same software image in the backup before running the config boot backup command. If both active and standby-hot controllers have different software images in the backup, and if you run the config boot backup command in the active controller, both the controllers reboot with their respective backup images breaking the HA pair due to a software mismatch.

A schedule reset applies to both the controllers in an HA environment. The peer controller reboots a minute before the scheduled time expires on the active controller. You can reboot the standby-hot controller from the active controller by entering the reset peer-system command if the scheduled reset is not planned.

If you reset only the standby-hot controller with this command, any unsaved configurations on the standby-hot controller is lost. Therefore, ensure that you save the configurations on the active controller before you reset the standby-hot controller. A preimage download is reinitiated if an SSO is triggered at the time of the image transfer. Only debug and show commands are allowed on the standby-hot controller. After a switchover, if a peer controller has a controller software release that is prior to Release 7.

The WLC, by default, maintains two images. These images are the primary image and the backup image. The primary image is the active image used by the WLC while the backup image is used as a backup for the active image. Here is an example. In order to remove or overwrite an image on the WLC, boot up the WLC with the image that you want to keep and perform an upgrade. This way, the new image replaces the backup image. In order to verify the version of WLC software that is running, log in to the controller after the system reboots.

You can use the debug transfer all enable command in order to view the events that occur during the controller software upgrade process. Here is an example, which shows the debug command output used and the for a successful software upgrade:. During the upgrade process, you might encounter errors. This section explains several common errors, along with typical causes and corrective actions you can take to complete the WLC software upgrade:.

Prerequisites Requirements In addition to basic networking knowledge and familiarity with the basic configuration and installation of Cisco Wireless LAN Controllers, ensure that you read the Guidelines and Recomendations present in the release notes.

You can reduce the network downtime using the following options: You can predownload the AP image. Components Used The information in this document is based on these software and hardware versions: An FTP server with the upgrade files stored. A Cisco WLC that runs 8. Follow these steps: Upload your controller configuration files to a server to back up the configuration files. The software releases are labeled as described here to help you determine which release to download.

Click a controller software release number: Early Deployment ED —These software releases provide new features and new hardware platform support as well as bug fixes. Maintenance Deployment MD —These software releases provide bug fixes and ongoing software maintenance.

Deferred DF —These software releases have been deferred. Select your installation site with safety as well as performance in mind. Electric power lines and phone lines look alike. For your safety, assume that any overhead line can kill you. Call your electric power company. Tell them your plans and ask them to come look at your proposed installation. This is a small inconvenience considering your life is at stake.

Plan your installation carefully and completely before you begin. Successfully raising a mast or tower is largely a matter of coordination. Each person should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble. When installing an antenna, remember:. Do not use a metal ladder. Do not work on a wet or windy day. Do dress properly—shoes with rubber soles and heels, rubber gloves, long-sleeved shirt or jacket.

If the assembly starts to drop, get away from it and let it fall. Remember that the antenna, mast, cable, and metal guy wires are all excellent conductors of electrical current. Even the slightest touch of any of these parts to a power line completes an electrical path through the antenna and the installer: you! If any part of an antenna system should come in contact with a power line, do not touch it or try to remove it yourself.

Call your local power company. They will remove it safely. If an accident should occur with the power lines, call for qualified emergency help immediately. Refer to the appropriate quick start guide or hardware installation guide for instructions on installing controllers and access points. Note To meet regulatory restrictions, all external antenna configurations must be professionally installed.

Personnel installing the controllers and access points must understand wireless techniques and grounding methods. Access points with internal antennas can be installed by an experienced IT professional. The controller must be installed by a network administrator or qualified IT professional, and the proper country code must be selected. Following installation, access to the controller should be password protected by the installer to maintain compliance with regulatory requirements and ensure proper unit functionality.

They are not compatible. Only the 5-pin mini Type B connector can be used. With this driver, you can plug and unplug the USB cable into and from the console port without affecting Windows HyperTerminal operations.

Note Only one console port can be active at a time. Click Standalone Controllers. Choose the USB driver file. Follow the prompts to install the USB driver. Note Some systems might also require an additional system file. You can download the Usbser. Some terminal emulation programs do not recognize a port higher than COM 4. To do so, follow these steps:. Step 2 From the list on the left side, choose Device Manager. Step 5 Click the Port Settings tab and click the Advanced button. This section describes important information about controllers and nonmesh lightweight access points.

Upgrading to controller release 6. All features included in a Wireless LAN Controller WPlus license are now included in the base license; this change is introduced in release 7. These WPlus license features are included in the base license:. The licensing change can affect features on your wireless LAN when you upgrade or downgrade software releases, so you should be aware of these guidelines:.

You can now purchase licenses to support additional access points on series controllers. The new additive licenses for 25, 50, or access points can be upgraded from all license tiers 12, 25, 50, , and access points.

The additive licenses are supported through both rehosting and RMAs. In this configuration, the controller acts as a transparent passthrough device. When using OTP, the client must only establish a single connection to the controller to function properly. The controller currently does not have any intelligence or checks to correct a client that is trying to establish multiple connections. In software releases prior to 6. In software release 6. If you enabled these attributes for You can create up to 50 access point groups for series controllers and controller network modules and up to access point groups for series controllers, AP Groups on Series Controllers, and access point groups for the Cisco WiSM, and the G wireless LAN controller switch.

You must disable IP-MAC address binding in order to use an access point in sniffer mode if the access point is joined to a series controller, a series controller, or a controller network module running software release 6. WLAN 1 must be enabled in order to use an access point in sniffer mode if the access point is joined to a series controller, a series controller, or a controller network module running software release 6.

If WLAN 1 is disabled, the access point cannot send packets. When controllers in the mobility list are running different software releases such as 5. It is supported only between controllers running the same and GD release such as 6. Guest tunneling works only between controllers running the same software release or between controllers running software release 4. Guest tunneling does not work among controllers running other combinations of software. Rogue Location Discovery Protocol RLDP is a controller feature that detects the presence of rogue access points that are connected to your wired network.

In this software release, RLDP operates with these limitations:. As a result, multiple clients can be assigned with the same IP address. To resolve any IP address conflicts, clients must release their existing IP address and request a new one. When you plug a controller into an AC power source, the bootup script and power-on self-test run to initialize the system. During this time, you can press Esc to display the bootloader Boot Options Menu.

The menu options for the series controllers are different than for other controller platforms. Bootloader Menu for Other Controller Platforms. Please enter your choice:. Enter 1 to run the current software, enter 2 to run the previous software, or enter 4 on a series controller or 5 on another controller platform to run the current software and set the controller configuration to factory defaults.

Do not choose the other options unless directed to do so. Note Refer to the Installation Guide or Quick Start Guide for your controller for more details on running the bootup script and power-on self-test. Cisco series controllers do not support fragmented pings on any interface. When a controller is configured to allow only When you configure the controller for If you have a firewall or access control list ACL between the controller and its access points that allows LWAPP traffic, before upgrading to software release 5.

The access points use a random UDP source port to reach these destination ports on the controller. In controller software release 5. Several messages might flood the message logs when the controller boots up. These messages appear because of a failure to read or delete several different configuration files.

These are low-severity messages that can safely be ignored. They do not affect controller functionality. These are some examples:. Cisco series access points are not supported for use with the Cisco IP phone. They can, however, be used with the Cisco and IP phones. The series access points may contain a bootloader older than version Units with old bootloaders do not generate a crash log when a crash occurs.

The crash log is disabled so that a crash does not corrupt the flash file system. Units with bootloader versions New series access points shipped from the factory contain new bootloader images, which fix the flash file system after it is corrupted during a crash without losing files.

Therefore, no user configuration is needed to enable a crash log on new series access points shipped from the factory. These examples show the output from the CLI commands in bold that you use to check the bootloader version on lightweight and autonomous series access points:. In controller software release 4.

When you upgrade a controller to 4. Note You cannot download a binary configuration file onto a controller running software release 7. Also, do not attempt to make changes to the configuration file. If you do so and then download the file to a controller, the controller displays a cyclic redundancy checksum CRC error while it is rebooting and returns the configuration parameters to their default values. Note You cannot modify the configuration files for , , and series controllers.

The ability to modify configuration files is available in controller software release 5. When you upgrade to controller software release 5. If you downgrade from controller software release 7. Access points might not join the controller, and you must manually reset the controller to Layer 3 to resolve this issue.

The dynamic interface gateway fails first and controller receives the GARP for the dynamic interface from the switch and sends it accordingly to the client. After the controller sends out the GARP, the getway for the ap manager fails and this packet is dropped.

The solution for this problem is as follows:. Access points running recent Cisco IOS versions transmit multicast frames at the highest configured basic rate and management frames at lowest basic mandatory rates, which can cause reliability problems. Because multicast frames are not retransmitted at the MAC layer, clients at the edge of the cell may fail to receive them successfully. If reliable reception is a goal, then multicast frames should be transmitted at a low data rate.

If support for high data rate multicast frames is required, then it may be useful to shrink the cell size and disable all lower data rates. Depending on your specific requirements, you can take the following action:. The controller disables the radio bands that are not permitted by the configured country of operation CSCsi Therefore, when you upgrade from an earlier software release to 4.

Controller software release 4. This feature affects only access points with 8 MB of flash the , , and series access points. All newer access points have a larger flash size than 8 MB. Note As of August , there are no oversized access point images, but as new features are added, the access point image size will continue to grow. The recovery image provides a backup image that can be used if an access point power-cycles during an image upgrade.

The best way to avoid the need for access point recovery is to prevent an access point from power-cycling during a system upgrade. If a power-cycle occurs during an upgrade to an oversized access point image, you can recover the access point using the TFTP recovery procedure. To recover the access point using the TFTP recovery procedure, follow these steps:.

Step 1 Download the required recovery image from Cisco. Step 2 Connect the TFTP server to the same subnet as the target access point and power-cycle the access point. The access point boots from the TFTP image and then joins the controller to download the oversized access point image and complete the upgrade procedure.

The multicast queue depth is packets on all controller platforms. This message appears when too many multicast messages are sent to the CPU. In controller software releases prior to 5. However, in software releases 5. There are currently no controller commands that can be entered to determine if the multicast receive queue is full. When the queue is full, some packets are randomly discarded. It is not supported for use with dynamic WEP. Cisco Aironet lightweight access points do not connect to the controller if the date and time are not set properly.

Set the current date and time on the controller before allowing the access points to connect to it. For controller software release 4. Also, we highly recommend that the time be set for networks that do not have location appliances. Note The time zone can be different for the controller and the location appliance, but the time zone delta must be configured accordingly, based on Greenwich Mean Time GMT. Access points use DFS to detect radar signals such as military and weather sources and then switch channels to avoid interfering with them.

After you change the position of the Regardless of the user display, the internal data is updated, and the transmit power output is changed accordingly. The default retransmit timeout value is 2 seconds and can be increased to a maximum of 30 seconds. An access point can be powered by a Cisco prestandard watt switch with Power over Ethernet PoE by entering this command:.

A Cisco prestandard watt switch does not support intelligent power management IPM but does have sufficient power for a standard access point. The following Cisco prestandard watt switches are available:. The enable version of this command is required for full functionality when the access point is powered by a Cisco prestandard watt switch. It is safe to use if the access point is powered by either an IPM switch or a power injector or if the access point is not using one of the watt switches listed above.

After you perform these functions on the controller, you must reboot the controller in order for them to take effect:. Rate-limiting is applicable to all traffic destined to the CPU from either direction wireless or wired. We recommend that you always run the controller with the default config advanced rate enable command in effect in order to rate-limit traffic to the controller and protect against denial-of-service DoS attacks.

You can use the config advanced rate disable command to stop rate-limiting of Internet Control Message Protocol ICMP echo responses for testing purposes. However, we recommend that you reapply the config advanced rate enable command after testing is complete. ICMP pings to other interfaces configured on the controller are not supported. Pinging from a network device to a controller dynamic interface may not work in some configurations. When pinging does operate successfully, the controller places Internet Control Message Protocol ICMP traffic in a low-priority queue, and the reply to ping is on best effort.

Pinging does not pose a security threat to the network. The controller rate limits any traffic to the CPU, and flooding the controller is prevented. Clients on the WLAN associated with the interface pass traffic normally. This version of Controller software release 7. As designed, series controllers do not forward IP subnet broadcasts from the wired network to wireless clients across the EoIP guest tunnel.

You must install software release 4. To prevent or block a wired or wireless client from accessing the management network on a controller from the wireless client dynamic interface or VLAN , the network administrator should ensure that there is no route through which to reach the controller from the dynamic interface or use a firewall between the client dynamic interface and the management network.

Cisco recommends that aggressive load balancing always be turned off either through the controller GUI or CLI in any wireless network that is supporting voice, regardless of vendor. When aggressive load balancing is turned on, voice clients can hear an audible artifact when roaming, and the handset is refused at its first reassociation attempt. It is not possible to enable or disable band selection and client load balancing globally through the controller GUI or CLI.

You can, however, enable or disable band selection and client load balancing for a particular WLAN. Band selection and client load balancing is enabled globally by default. To enable it, you must configure the access point with a new username and password when it joins the controller. Enter this command using the controller CLI to push a new username and password to the access point:.

There are some cases where the prestage configuration for LWAPP access points is disabled and the access point displays the following error message when the CLI commands are applied:. If a client is not able to connect to an access point, and the security policy for the WLAN and client are correct, the client has probably been disabled.

If the client is disabled, click Remove to clear the disabled state for that client. The client automatically comes back and, if necessary, reattempts authentication. Automatic disabling happens as a result of too many failed authentications. Clients disabled due to failed authorization do not appear on the permanent disable display. This display is only for those MACs that are set as permanently disabled by the administrator.

Management usernames and local netuser names must be unique because they are stored in the same database. That is, you cannot assign the same name to a management user and a local netuser. The controller bootloader stores a copy of the active primary image and the backup image.

If the primary image becomes corrupted, you can use the bootloader to boot with the backup image. With the backup image stored before rebooting, be sure to choose Option 2: Run Backup Image from the boot menu to boot from the backup image. Then, upgrade with a known working image and reboot the controller. Because of a caching problem in the Internet Explorer 5. To correct this problem, clear the history or upgrade your workstation to Internet Explorer 6.

Client card implementations may mitigate the effectiveness of ad-hoc containment. Using these standard values presents a security risk. Therefore, Cisco strongly advises that you change these values. Note SNMP v3 is time sensitive. Make sure that you have configured the correct time and time zone on your controller. The DirectStream feature from the controller does not work for clients behind workgroup bridges and the stream is denied.

This feature is not supported in 7. The controller does not support transmitting jumbo frames. This hardware feature is not supported on series controllers:. These software features are not supported on series controllers:. Note For series controllers, you are not required to configure an AP-manager interface. The management interface acts like an AP-manager interface by default, and the access points can join on this interface. Note The series controllers bridge these packets by default.

If desired, you can use ACLs to block the bridging of these protocols. In a crowded RF environment, clients may not be able to detect the desired SSID because of internal table limitations. Sometimes disabling and then enabling the client interface forces a rescan. Your RF environment needs to be controlled. Cisco UWN rogue access point detection and containment can help you to enforce RF policies in your buildings and campuses. The controller image is supported for use with only series controllers.

Do not install the image on a controller. Otherwise, errors may occur. Install only the image on a controller. It is possible to run a controller image on a series controller, but Cisco Aironet , , and series access points will not be able to connect to the controller. When upgrading a controller from operating system release 2.

For series controllers and the Cisco WiSM, instead of using a preauthentication ACL, the network manager must configure the external web server IP address using this command:. Note IP-address is the address of any web server that performs external web authentication.

Note Make sure to format the script to avoid any extra characters or spaces before using the web authentication template. When the port status on the controller changes, the switch status does not get changed. This is a known issue.

For example, when the controller port goes down, the switch port is still in administrable state. This has been resolved in Cisco Series Controllers. The unified and autonomous access point do not support the mac-address command for the wireless interfaces. When invoked, the command executes, but can cause the access point to fail. In releases prior to 6. This section describes important information about controllers and mesh access points.

With the 7. From software release 7. The public safety band 4. For example, if radar is detected on the uplink radio of a child access point, the parent is informed so that it can change the channel of the downlink radio. The parent informs the child about the channel change, so that the child access point can set the new channel on its uplink radio and does not have to scan again to rejoin the parent on the new channel.

The serial backhaul access point consists of three radio slots. Radios in slot 0 operate in a 2. The downlink and uplink radios operate in a 5-GHz band and are primarily used for backhaul. With the Universal Client Access feature, client access is allowed over slot 1 radios with the extended universal client access feature and client access is also allowed over slot 2 radios. The two By default, client access is disabled over both the backhaul radios.

This feature enables you to execute commands to the cable modem from the privileged mode of the CLI. This command takes a text string and sends it to the cable modem UART interface. The Cable modem interprets the text string as one of its own CLI commands. The response is captured and displayed to the IOS console.

Up to characters are displayed from the cable modem. Any text beyond the characters is truncated. A Workgroup Bridge WGB is a small standalone unit that can provide a wireless infrastructure connection for Ethernet-enabled devices. Devices that do not have a wireless client adapter to connect to the wireless network can be connected to the WGB through the Ethernet port.

Thus, wired clients get access to the wireless network. In the current architecture, while an autonomous AP functions as a workgroup bridge, only one radio interface is used for controller connectivity, an Ethernet interface is used for wired client connectivity, and another radio interface is used for wireless client connectivity.

In a practical scenario, dot11radio 1 5 GHz can be used to connect to the controller using a mesh infrastructure , an Ethernet interface can be used for wired clients, and dot11radio 0 2. This scenario can improve the serviceability of a workgroup bridge without any extra cost. Depending on your network requirements, dot11radio 1 or dot11radio 0 can be used for client association or controller connectivity. Access points with two radios certainly gives better advantage because one radio can be used for client access and the other radio can be used for accessing the access points.

Also, wireless clients on the second radio do not get disassociated by the WGB when it loses its uplink or in a roaming scenario. In this scenario, you must configure one radio as Root radio role and the second radio as WGB radio role. For using this feature, the WGB must use a release later than This feature does not support downstream broadcasting of per-VLAN. Layer-2 multicast is not supported for WGB Ethernet clients. The following controller features are not supported on mesh networks:.

The following sections lists Open Caveats and Resolved Caveats for Cisco controllers and lightweight access points for version 7. These caveat titles are not intended to be read as complete sentences because the title field length is limited. In the caveat titles, some truncation of wording or punctuation might be necessary to provide the most complete and concise description.

The only modifications made to these titles are as follows:. Note If you are a registered cisco. Table 6 lists open caveats in controller software release 7. Multicast does not work without fragmentation if IGMP snooping is enabled. Counters do not clear during an intracontroller roaming of SIP-reserved bandwidth calls.

Unable to ping APs directly connected to a controller. Packets sourced from the service port are sent from the controller when they are not connected. The default group for ap-groups does not contain all SSIDs. The per-user bandwidth contract blocks all traffic when set to 0. Clients are not removed from Temporary Exclusion List after 60 seconds.

The alarm light displays solid amber, the system light displays amber, and the console access is lost. Rebooting controller has no effect. The show client tsm command does not display full output. AP deauthenticated when the power capability is unacceptable 0xa.

Upgrading 4. A mobile scan process misses probe responses and is doing bad parent roaming. WGB: Multiple parents created during roaming traffic were disrupted. The AP, which is not correctly primed, keeps reconnecting with the master. The Wireless LAN Controller does not appear to respond to SNMP requests if the source address of the request comes from a subnet that is configured as a dynamic interface.

Table 7 lists caveats resolved in controller software release 7. QoS profiles per-user bandwidth contracts are not restricting traffic. The PMK cache is not updated after a refresh authentication. The primary discovery request is not processed for an access point priority scenario. The management interface is unreachable via a different subnet. The WCS startup fails for non-U. D3 Web-auth redirections fail during failover scenarios.

WCS 6. HREAP is locking up due to a wedge input queue on the radio interface. The show ap image predownload version column shows the wrong version. This is seen in the HMR release. Enabling broadcast forwarding verses multicast forwarding via the CLI.

Wired Guest access user is not redirected to webauth page after sometime approximately 10 minutes before logging in, which results in a timeout. The authentication trap flag does not get saved on the reboot. The controller fails to redirect web authentication to an external server. The debug pm ssh-engine enable packet command does not work.

No mobility record was found for the peer error seen for the self IP address. Noise and channel measurements are not done on all DCA channels. Clients cannot be deleted from the exclusion list if they are not present in the association list. A wrong message appears on the GUI when the controller image is upgraded while the AP downloads the image. WCS 4. Add user input required commands to the CLI template parser. The show ap summary does not show the AP names.
