Controller Platforms Not Supported

The following controller platforms are not supported:

  • Cisco 4400 Series Wireless LAN Controller
  • Cisco 2100 Series Wireless LAN Controller
  • Cisco Catalyst 3750G Integrated Wireless LAN Controller
  • Cisco Catalyst 6500 Series/7600 Series Wireless Services Module (WiSM)
  • Cisco Wireless LAN Controller Module (NM/NME)

What’s New in This Release?

This section provides a brief description of what is new in this release. For more information about instructions on how to configure these features, see the Cisco Wireless LAN Controller Configuration Guide .

  • The virtual wireless LAN controller is software that can run on hardware that is compliant with an industry standard virtualization infrastructure. Virtual wireless LAN controllers provide flexibility for users to select the hardware based on their requirement.

We recommend that you have the following hardware to host a virtual controller:

Cisco UCS R210-2121605W Rack Mount Server (2 RU)

IBM x3550 M3 server

ISR G2 Services Ready Engine (SRE) using UCS Express

For more information, see http://www.cisco.com/en/US/products/ps12723/tsd_products_support_series_home.html

The virtual wireless LAN controller does not have a Manufacturer Installed Certificate (MIC). Therefore, APs cannot validate the virtual controller unless they are using a 7.3-based image such as the follows:

12.4(25e)JAL for 1130/1240 series APs

15.2(2)JA for 1250/1260/1140/2600/3500/3600 series APs

Follow either of the following two ways to resolve this:

Install the abovementioned IOS images manually on the AP, join the APs to a hardware based controller using the 7.3 software release to download the image, and disable hash validation by entering the config certificate ssc hash validation disable command.

Configure the virtual controller as a mobility member and include the hash value so that the APs can validate the virtual controller.


Note It is not possible to directly join an AP that has a 7.2 or older image of the controller with the virtual wireless LAN controller. You must first join the AP with a different controller model, say a 5500 or Flex 7500 series controller that is using the 7.3 software or later releases, and then join the AP with the virtual wireless LAN controller.


  • Cisco 8500 Series Controllers are introduced with support for local mode, FlexConnect, and mesh modes. The Cisco 8500 Series Controllers support 6000 APs, 64,000 clients, 2000 FlexConnect groups, 6000 AP groups, 100 APs per FlexConnect group, and up to 4095 VLANs. A Cisco 8500 Series Controller can support up to 24,000 rogue APs and 32,000 rogue clients. For more information, see http://www.cisco.com/en/US/products/ps12722/tsd_products_support_series_home.html
  • Increased scale for Cisco Flex 7500 Series Controllers to support 6000 APs, 64000 clients, 2000 FlexConnect groups, 6000 AP groups, 100 APs per FlexConnect group, and up to 4096 VLANs.
  • The number of rogue APs and rogue clients that can be detected per platform is increased (see Table 1-1 ).

  • The Cisco Aironet 2600 Series Access Points are supported. For more information, see http://www.cisco.com/en/US/products/ps12534/index.html .
  • High availability (HA) in controllers allows you to reduce the downtime of the wireless networks, due to the failover of controllers. In this release, a 1:1 (Active:Standby-Hot) AP stateful switchover (AP SSO) is supported. In an HA architecture, one controller is configured as the primary controller and another controller as the secondary controller.

After you enable HA, the primary and secondary controllers are rebooted. During the boot process, the primary controller role is negotiated as active and the secondary controller as standby-hot. After a switchover, the secondary controller becomes the active controller and the primary controller becomes the standby-hot controller. After subsequent switchovers, the roles are interchanged between the primary and the secondary controllers. The reason for switchovers could be due to manual trigger or a controller or network failure.


Note Internal DHCP is not supported.


  • FlexConnect-related features:

Split tunneling allows the traffic sent by a client to be classified based on the packet contents. The matching packets are locally switched and the rest of the traffic is centrally switched. The traffic that is sent by the client that matches the IP address of the device present in the local site can be classified as locally switched traffic and the rest of the traffic as centrally switched.

This feature is supported on the AP1040, AP1140, AP1260, AP2600, AP3500, and AP3600 access points.

Support to configure Network Address Translation (NAT) and Port Address Translation (PAT) on FlexConnect locally switched WLANs is added. You must enable Central DHCP Processing to enable NAT and PAT.

This feature is supported on the AP1040, AP1140, AP1260, AP2600, AP3500, and AP3600 access points.

Support for the Point to Point Protocol (PPP) and the Point to Point Protocol over Ethernet (PPPoE) is added for APs in FlexConnect mode. You must configure PPPoE submode when the AP is in FlexConnect mode.

This feature is supported on the AP1040, AP1140, AP1260, AP2600, AP3500, and AP3600 access points.

This release extends WGB/uWGB support to FlexConnect APs for locally switched WLANs.

WGB is supported on all FlexConnect APs: AP1040, AP1130, AP1140, AP1240, AP1250, AP1260, AP1520, AP2600, AP3500, AP3600, AP801, and AP802.

This release extends support for 802.11u in FlexConnect mode.

802.11r Fast Transition is now supported on FlexConnect APs in central and locally switched WLANs.

VLAN-based local and central switching is supported. When a AAA server returns a VLAN configured for a client, the VLAN is configured on the local IEEE 802.1Q link, the AP bridges the traffic locally. If the VLAN is not configured on the AP uplink, the AP tunnels the traffic back to the controller. The controller bridges the traffic into the corresponding VLAN from where the traffic is transported toward the next routing instance for further processing.

  • Table 1-3 lists the 802.11r L2 and L3 roaming rates that are supported in this release on the 5500 and WiSM2 controllers:

  • This release extends support for HotSpot 2.0 specifications, where APs in mesh mode and APs in FlexConnect mode in locally switched WLANs are also supported.
  • IPv6 address support is added for rogue client and wIPS alarms. Three new wIPS signatures are supported.
  • This release extends support for IPv6 on Cisco Wireless Controller on Cisco Services-Ready Engine (SRE).
  • Right to Use (RTU) licensing allows you to enable a desired AP license count on the controller after you accept the End User License Agreement (EULA). This process enables you to add AP counts on a controller without interacting with external tools.

RTU licensing is supported only on Cisco Flex 7500 Series and Cisco 8500 Series Wireless LAN Controllers.

  • This release extends support to video CAC for calls that are based on TSpec and SIP. For example:

TSpec-based video calls including 802.11n clients.

Facetime and Cius video call applications that use SIP unencrypted signaling.

  • You can configure WLANs to do 802.1X authentication of clients if MAC authentication with static WEP fails. Clients are deauthenticated if they fail the 802.1X authentication. If MAC authentication is successful and clients send a request to start 802.1X authentication, clients have to pass the 802.1X authentication to be allowed to send data traffic. Otherwise, clients are deauthenticated. If clients choose not to have 802.1X authentication, they can be declared as authenticated if they pass MAC authentication.
  • Proxy Mobile IPv6 is a network-based mobility management protocol that supports a mobile node by acting as the proxy for the mobile node in any IP mobility-related signaling. The mobility entities in the network track the movements of the mobile node and initiate the mobility signaling and set up the required routing state.

The main functional entities are the Local Mobility Anchor (LMA) and Mobile Access Gateway (MAG). The LMA maintains the reachability state of the mobile node and is the topological anchor point for the IP address of the mobile node. The MAG performs the mobility management on behalf of a mobile node. The MAG resides on the access link where the mobile node is anchored. The controller implements the MAG functionality.


Note PMIPv6 MAG functionality is supported only on Cisco 5500 Series Controllers, Cisco 8500 Series Controllers, and Cisco WiSM2.



Note In this release, the Cisco 8500 Series Controllers can support a maximum of 40,000 PMIPv6 clients out of the 64,000 clients that are supported.


  • You can enable or disable IPv6 globally by entering this command:

config ipv6 { enable | disable }

  • You can upload the output of the show run-config command onto an FTP server by entering this command:

transfer upload datatype run-config

  • Support for detection and forwarding of the first HTTP packet with a user-agent attribute from a client per session to profile the client, where the controller acts as a collector, is added in this release.
  • To resolve issues such as voice and security on wireless networks, you might need to dump packets from the AP for analysis while the AP continues to operate normally. The packets can be dumped onto an FTP server. This process of dumping packets for analysis is called Packet Capture. Use the controller to start or stop packet capture for clients. You can choose the type of packets that need to be captured using the controller.
  • In this release, RF profiles incorporate new configurations, which are specially targeted at high-density and stadium environments. These new configurations are as follows:

High-density configurations

Stadium vision configurations

Out-of-the-box AP configurations

Band select configurations

Load balancing configurations

Coverage hole mitigation configurations

  • VLAN tagging on Ethernet interfaces is supported. You can configure VLAN tagging on the Ethernet interface either directly from the AP console or through the controller and Cisco Prime Infrastructure. You must save the configuration in flash and all CAPWAP packets use the VLAN tag as configured with all the locally switched traffic, which is not mapped to a VLAN. When enabled, the CAPWAP packets from the AP are forwarded through the trunk VLAN. If it fails, the AP falls back to the untagged mode.
  • DHCP Option 82 enhancement—You can also specify the name and the SSID of the access point to the DHCP Option 82 payload.
  • RADIUS CallStationID enhancement—You can also specify the name and the SSID of the access point to determine the RADIUS CallStationID.
  • The bandwidth contract feature is enhanced so that rate limits can be defined on both upstream and downstream traffic. Rate limits can be defined per SSID and/or specified as a maximum rate limit for all clients. These rate limits can be individually configured. This feature is supported on AP1140, AP1040, AP3500, AP3600, AP1250, and AP1260. In centrally switched WLANs, the downstream traffic is rate limited by the controller and the upstream is rate limited by the APs. In local switched WLANs, both upstream and downstream are traffic are rate limited by the APs.
  • RADIUS source interface is aware of the AP group, which allows sourcing the RADIUS packets from the interface assigned to the AP group. To allow partitioning of a network into different subnets, AP groups can be used to provide site-specific VLANs, where each VLAN has its own IP subnet that can be identified. For all client associations to the site-specific VLAN on the AP, all RADIUS interactions must be sourced from the IP address of that site-specific VLAN, which maps an AP group to a site-specific VLAN and maps the VLAN to a unique IP subnet.
  • Increased RADIUS servers per WLAN from 3 to 6.
  • Added SNMP support to swap controller images (primary and standby).
  • AP searches and renaming of APs are based on serial numbers.
  • Usernames are displayed in client summaries.
  • This release is compliant with the Federal Information Processing Standard (FIPS) 140-2 standard for wireless controllers and APs.
  • This release introduces two new AP1552 models:

AP1552CU

AP1552EU

Local, FlexConnect, Monitor, Rogue Detector, and Sniffer modes

VideoStream in Local mode

HotSpot 2.0 in Local mode

VoWLAN

Band Select

Datagram Transport Layer Security (DTLS)


Note Support is added for DTLS data plane encryption for the AP1552s in Local and FlexConnect mode.


CleanAir of 5-GHz radio

  • Mesh outdoor access points support local mode. In this mode, the AP can handle clients on its assigned channel or while monitoring all channels on the band over a 180-second period. During this time, the AP listens on each channel for 50 milliseconds for rogue client beacons, noise floor measurements, interference, and IDS events. The AP also scans for CleanAir interference on the channel.
  • The operating frequency in the 5-GHz band for the 1550 series access points has been increased from 5.850 GHz to 5.875 GHz.
  • A new country domain has been added for India. The –D domain supports the 20-MHz channels, which are 169 (5.845 GHz) and 173 (5.865 GHz), and the 40-MHz channel pair, which is 169/173 (5.855 GHz).
  • You can activate CleanAir Advisor when you enable CleanAir on a backhaul radio. CleanAir Advisor generates Air Quality Index (AQI) and Interfere Detection Reports (IDRs), but the reports are displayed only in the controller. No action is taken through Event Driven RRM (ED-RRM).
  • You can order AP1552E/EU with an Ethernet Passive Optical Network (EPON) SFP as an add-on. The EPON SFP provides Gigabit data rates. EPON SFP is not an orderable feature on the AP1552. You must order it separately and install it.

Upgrading to Controller Software Release 7.3.101.0

Guidelines and Limitations

  • The 7.3.101.0 controller software release is not compatible with Cisco Prime Network Control System (NCS) 1.1.1.24. Cisco Prime Infrastructure 1.2 is required to support the new features in controllers introduced in the 7.3.101.0 controller software release. Cisco Prime Infrastructure 1.2 is the subsequent version of Cisco Prime Network Control System (NCS) 1.1.1.24
  • If you require a downgrade from one release to another, you might lose the configuration from your current release. The workaround is to reload the previous controller configuration files saved on the backup server or to reconfigure the controller.
  • It is not possible to directly upgrade to the 7.3.101.0 release from a release that is older than 7.0.98.0.
  • You can upgrade or downgrade the controller software only between certain releases. In some instances, you must first install an intermediate release prior to upgrading to software release 7.3.101.0. Table 1-5 shows the upgrade path that you must follow before downloading software release 7.3.101.0.

7.2. or later 7.2 releases

You can upgrade directly to 7.3.101.0

  • When you upgrade the controller to an intermediate software release, you must wait until all of the access points that are associated with the controller are upgraded to the intermediate release before you install the latest controller software. In large networks, it can take some time to download the software on each access point.
  • If you upgrade to the controller software release 7.3.101.0 from an earlier release, you must also upgrade to Cisco Prime Infrastructure 1.2 and MSE 7.3.101.0.
  • You can upgrade to a new release of the controller software or downgrade to an older release even if Federal Information Processing Standard (FIPS) is enabled.

• When you upgrade to the latest software release, the software on the access points associated with the controller is also automatically upgraded. When an access point is loading software, each of its LEDs blinks in succession.

• We recommend that you access the controller GUI using Microsoft Internet Explorer 6.0 SP1 (or a later release) or Mozilla Firefox 2.0.0.11 (or a later release).

  • Cisco controllers support standard SNMP Management Information Base (MIB) files. MIBs can be downloaded from the Software Center on Cisco.com.

• The controller software is factory installed on your controller and automatically downloaded to the access points after a release upgrade and whenever an access point joins a controller. We recommend that you install the latest software version available for maximum operational benefit.

  • We recommend that you install Wireless LAN Controller Field Upgrade Software for Release 1.7.0.0-FUS, which is a special AES package that contains several system-related component upgrades. These include the bootloader, field recovery image, and FPGA/MCU firmware. Installing the FUS image requires special attention because it installs some critical firmware. The FUS image is independent of the runtime image. For more information, see http://www.cisco.com/en/US/docs/wireless/controller/release/notes/fus_rn_1_7_0_0.html .

• Ensure that you have a TFTP or FTP server available for the software upgrade. Follow these guidelines when setting up a TFTP or FTP server:

Ensure that your TFTP server supports files that are larger than the size of the controller software release 7.3.101.0. Some TFTP servers that support files of this size are tftpd32 and the TFTP server within the Prime Infrastructure. If you attempt to download the 7.3.101.0 controller software and your TFTP server does not support files of this size, the following error message appears: “TFTP failure while storing in flash.”

If you are upgrading through the distribution system network port, the TFTP or FTP server can be on the same or a different subnet because the distribution system port is routable.

  • 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 5500 differ from the menu options for the other controller platforms.

Bootloader Menu for 5500 Series Controllers:

Boot Options
Please choose an option from below:
1. Run primary image
2. Run backup image
3. Change active boot image
4. Clear Configuration
5. Format FLASH Drive
6. Manually update images
Please enter your choice:

Bootloader Menu for Other Controller Platforms:

Boot Options
Please choose an option from below:
1. Run primary image
2. Run backup image
3. Manually update images
4. Change active boot image
5. Clear Configuration
Please enter your choice:

Enter 1 to run the current software, enter 2 to run the previous software, enter 4 (on a 5500 series controller), or enter 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 See the Installation Guide or the Quick Start Guide for your controller for more details on running the bootup script and power-on self-test.


  • 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.

  • Control which address(es) are sent in CAPWAP discovery responses when NAT is enabled on the Management Interface using the following command:

config network ap-discovery nat-ip-only { enable | disable }

where:

enable — Enables use of NAT IP only in a discovery response. This is the default. Use this command if all APs are outside of the NAT gateway.

disable —Enables use of both NAT IP and non-NAT IP in a discovery response. Use this command if APs are on the inside and outside of the NAT gateway; for example, Local Mode and OfficeExtend APs are on the same controller.


Note To avoid stranding APs, you must disable AP link latency (if enabled) before you use the disable option for the config network ap-discovery nat-ip-only command. To disable AP link latency, use the config ap link-latency disable all command.


  • You can configure 802.1p tagging by using the config qos dot1p-tag { bronze | silver | gold | platinum } tag. For the 7.2.103.0 and later releases, if you tag 802.1p packets, the tagging has impact only on wired packets. Wireless packets are impacted only by the maximum priority level set for QoS.
  • You can reduce the network downtime using the following options:

You can predownload the AP image.

For FlexConnect access points, use the FlexConnect AP upgrade feature to reduce traffic between the controller and the AP (main site and the branch). For more information about the FlexConnect AP upgrade feature, see the Cisco Wireless LAN Controller Configuration Guide .


Note Predownloading a 7.3.101.0 version on a Cisco Aironet 1240 access point is not supported when upgrading from a previous controller release. If predownloading is attempted to a Cisco Aironet 1240 access point, an AP disconnect will occur momentarily.


  • Do not power down the controller or any access point during the upgrade process; otherwise, you might corrupt the software image. Upgrading a controller with a large number of access points can take as long as 30 minutes, depending on the size of your network. However, with the increased number of concurrent access point upgrades supported, the upgrade time should be significantly reduced. The access points must remain powered, and the controller must not be reset during this time.
  • If you want to downgrade from the 7.3.101.0 release to a 6.0 or an older release, do either of the following:

Delete all WLANs that are mapped to interface groups and create new ones.

Ensure that all WLANs are mapped to interfaces rather than interface groups.

  • After you perform these functions on the controller, you must reboot the controller for the changes to take effect:

Enable or disable link aggregation (LAG)

Enable a feature that is dependent on certificates (such as HTTPS and web authentication)

Add a new license or modify an existing license

Increase the priority for a license

Enable the HA

Install SSL certificate

Configure the database size

Install vendor device certificate

Download CA certificate

Upload configuration file

Install Web Authentication certificate

Changes to management or virtual interface

TCP MSS

  • Ensure that you apply the calibration fix for AP1260 and AP3500 models (see the resolved caveat CSCty68030). This addresses a manufacturing calibration issue on the AP1260 and AP3500 models (VID V01). For more information, see https://supportforums.cisco.com/docs/DOC-25460 .

Special Notes for Licensed Data Payload Encryption on
Cisco Wireless LAN Controllers

Datagram Transport Layer Security (DTLS) is required for all Cisco 600 Series OfficeExtend Access Point deployments to encrypt data plane traffic between the APs and the controller. You can purchase Cisco Wireless LAN Controllers with either DTLS that is enabled (non-LDPE) or disabled (LDPE). If DTLS is disabled, you must install a DTLS license to enable DTLS encryption. The DTLS license is available for download on Cisco.com.

Important Note for Customers in Russia

If you plan to install a Cisco Wireless LAN Controller in Russia, you must get a Paper PAK, and not download the license from Cisco.com. The DTLS Paper PAK license is for customers who purchase a controller with DTLS that is disabled due to import restrictions but have authorization from local regulators to add DTLS support after the initial purchase. Consult your local government regulations to ensure that DTLS encryption is permitted.


Note Paper PAKs and electronic licenses available are outlined in the respective controller datasheets.

Open Caveats

Table 1-8 lists the open caveats in the 7.3.101.0 controller software release.

 

Table 1-8 Open Caveats

ID
Description

CSCub67462

Ethernet bridged clients on AP3600 models are unable get IP.

Symptom : Ehternet bridging does not work with AP3600e/i models.

Conditions : AP3600 in bridge mode and Ethernet bridging enabled.

Workaround : None.

CSCub26289

Controller does not raise alarm after automatic configuration changes after an upgrade.

Symptom : Following the resolution for the CSCty45920 issue in the 7.3 release, the controller changes the overlapping subnet interface IP addresses to all zeros without raising any visible alarm on the GUI or the CLI. The controller does not log a message on msglog, traplog, or after entering the show invalid-config command. After the controller is upgraded and the controller reboots with all the zero IP address interfaces, there could be network outages if you do not know about these silent configuration changes.

Conditions : Controller had overlapping subnet interfaces before upgrading the controller software release that had the fix for the CSCty45920 issue.

Workaround : Ensure that the controller does not have overlapping interfaces before the upgrade.

CSCtz07676

Controller cannot establish SXP connection with a Cisco Nexus 7000 Series switch.

Symptom : An SXP connection from the controller to the Cisco Nexus 7000 Series switch reports the On state on the controller side while the switch reports the Waiting for Response state.

Conditions : Establishing SXP connection between the controller and ASA.

Workaround : Add an intermediate device that supports SXPv2 between the controller and the Cisco Nexus 7000 Series switch.

CSCua45032

Outer DSCP is 46 with client gold QoS level policy.

Symptom : The outer DSCP is 46 with a gold QoS level policy for the client.

Conditions : During AAA override of QoS values.

Workaround : None.

CSCub42439

An AP sends CAPWAP control frame incorrectly to the client.

Symptom : AP Sends CAPWAP control frame to client incorrectly when gateway IP address of AP is assigned to the client.

Conditions : The gateway IP address of the AP is assigned to the client. The client is pinging the AP for a few seconds, but the AP starts to send CAPWAP control frames to the client incorrectly.

Workaround : None.

CSCtz76132

AP stops working during check HEAP while validating allocated memory pool.

Symptom : AP1130 stops working with crashlog entries including messages such as the following:

%SYS-3-CPUHOG: Task is running for (1992)msecs, more than (2000)msecs (29/26),process = Check heaps.

Conditions : AP1130 connected to a controller on the 7.0.230.0 software release.

Workaround : None.

CSCtz93407

Mesh traps have invalid content.

Symptom : All mesh traps have invalid information on SNR, hop counts, and so on:

Mesh node '88:f0:77:XX:XX:XX' has detected low SNR '0' from its parent Mesh node '00:02:cd:fc:00:00'.

Mesh node '88:f0:77:XX:XX:XX' has detected high SNR '255 db' from its parent Mesh node '00:01:2e:bf:00:00'.

Parent MAC does not exist, and SNR is incorrect.

Excessive hop count of 56 on mesh node 88:f0:77:XX:XX:XX. It is not possible to have 56 hops on the topology.

Conditions : No associated condition.

Workaround : None.

CSCua45747

AP stops working during ARP processing.

Symptom : AP stops working. This is a very low-frequency event (one AP, once a month).

Conditions : ARP processing.

Workaround : Reboot the AP.

CSCtw67184

Controller loses RAID after a power interruption.

Symptom : During the boot process, the following error message appears on the attached monitor or on the serial console:

"All the disks from your previous configuration are gone. If this is an unexpected message, then please power off your system and check your system and check your cables to ensure all disks are present.

Press any key to continue or C to load the configuration utility."

When the Spacebar key is pressed, the system could not boot from the disk.

Conditions : The Cisco Flex 7500 Series Controller had an unexpected power interruption (the power plug was pulled while the system was operational). After the reboot, the RAID card could not find its configuration in the flash memory and therefore it could not boot.

Workaround : Enter the WebBIOS, which is a RAID management tool. There are two versions of this tool: one that uses extensive menus and requires an attached monitor and another that is based on the command-line interface (CLI).

The CLI version can be accessed from the serial console. You are prompted for this on the serial console after the error message is displayed.

1. Press Ctrl-Y to enter the CLI version of the WebBIOS tool in the following command:

-CfgForeign -Import -a0

2. Reboot the server.

Further Problem Description : When the Spacebar key is pressed, the system could not boot from the disk. During bootup, the LSI WebBIOS loads correctly and shows two physical disks but no virtual disks. It appears that the RAID configuration that was present in the system was lost.

The controller encountered an unexpected power interruption (the power plug was pulled while the system was operational). After the reboot, the RAID card could not find its configuration in the flash memory and therefore it could not boot. The flash configuration was corrupted or deleted due to the power interruption. The RAID card keeps a backup of the configuration on the hard drives. However, when the card loses the configuration information that is present in the flash, the card does not automatically get the backup configuration information from the hard drives. The information on the hard drives is considered a foreign configuration that requires your intervention.

The system waits for you to take action. Note that all the data on the hard drives are still intact.

CSCua09530

Invalid tar magic error on custom WebAuth download on a Cisco Wireless Controller on Cisco Services-Ready Engine (SRE).

Symptom : Downloading a custom WebAuth bundle tar file to a Cisco Wireless Controller on Cisco Services-Ready Engine (SRE) might fail with the following output:

TFTP receive complete... extracting webauth files.

tar: invalid tar magic

Error extracting webauth files.

Conditions : Tar file created with 7zip. The same tar file might successfully download to other controller platforms.

Workaround : Tar the custom WebAuth files using the unix tar utility.

tar -cvf <output.tar> login.html

CSCub88941

802.1X clients fail to get authenticated with the maximum number of APs associated.

Symptom : 802.1X clients fail to get authenticated with the maximum number of APs associated with the controller.

Conditions : Issue is related to the number of APs supported per controller platform with the AP priority feature enabled.

For example, Cisco WiSM2 can support a maximum of 1000 APs, which means 2000 802.1X control blocks are created in the controller (one per radio, two per AP). When a higher priority AP associates with the controller, the lower priority APs are dissociated. However, 802.1X control blocks are not deleted. As a result, when an 802.1X client tries to get authentcated from the newly joined AP, the controller fails to create 802.1X control block for that client, resulting in the failure of client authentication.

Workaround : Disable the AP priority feature on the controller by entering this command:

config network ap-priority disable

Safety Information

Follow the guidelines in this section to ensure proper operation and safe use of the controllers and access points.

FCC Safety Compliance Statement

FCC Compliance with its action in ET Docket 96-8, has adopted a safety standard for human exposure to RF electromagnetic energy emitted by FCC-certified equipment. When used with approved Cisco Aironet antennas, Cisco Aironet products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper operation of this radio device according to the instructions in this publication results in user exposure substantially below the FCC recommended limits.

Safety Precautions

For your safety, and to help you achieve a good installation, read and follow these safety precautions. They might save your life!

1. If you are installing an antenna for the first time, for your own safety as well as others, seek professional assistance. Your Cisco sales representative can explain which mounting method to use for the size and type of antenna you are about to install.

2. 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.

3. 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.

4. 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.

5. When installing an antenna, remember:

a. Do not use a metal ladder.

b. Do not work on a wet or windy day.

c. Do dress properly—shoes with rubber soles and heels, rubber gloves, long-sleeved shirt or jacket.

6. 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!

7. 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.

8. If an accident should occur with the power lines, call for qualified emergency help immediately.

Installation Instructions

See 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 installed by experts.


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.
