Upgrading to Controller Software Release 7.4.100.60

Guidelines and Limitations

When H-REAP access points that are associated with a controller that has all the 7.0.x software releases that are prior to 7.0.240.0 upgrade to the 7.4.100.60 release, the access points lose their VLAN support configuration if it was enabled. The VLAN mappings revert to the default values of the VLAN of the associated interface. This issue does not occur if you upgrade from 7.0.240.0 or later 7.0.x release to the 7.4.100.60 release.

While a client sends an HTTP request, the Controller intercepts it for redirection to login page. If the HTTP request intercepted by Controller is fragmented, the Controller drops the packet as the HTTP request does not contain enough information required for redirection.

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.

If you are using a Cisco 2500 Series controller and you intend to use the Application Visibility and Control (AVC) and NetFlow protocol features, you must install Wireless LAN Controller Field Upgrade Software for Release 1.8.0.0-FUS. This is not required if you are using other controller hardware models. For more information, see http://www.cisco.com/en/US/docs/wireless/controller/release/notes/fus_1_8_0_0.html.

When you enable LAG on a Cisco 2500 Series Controller with which a direct-connect access point is associated, the direct-connect access point dissociates with the controller. When LAG is in enabled state, the direct-connect access points are not supported. For direct-connect access points to be supported, you must disable LAG and reboot the controller.

If LAG is enabled on the Cisco 2500 Series Controller and the controller is downgraded to a non-LAG aware release, the port information is lost and it requires manual recovery.

After you upgrade to the 7.4 release, networks that were not affected by the existing preauthentication ACLs might not work because the rules are now enforced. That is, networks with clients configured with static DNS servers might not work unless the static server is defined in the preauthentication ACL.

On 7500 controllers if FIPS is enabled, the reduced boot options are displayed only after a bootloader upgrade.


Note Bootloader upgrade is not required if FIPS is disabled.


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 7.4.100.60 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 7.4.100.60. Table 2 shows the upgrade path that you must follow before downloading software release 7.4.100.60.

Table 2 Upgrade Path to Controller Software Release 7.4.100.60  

Current Software Release
Upgrade Path to 7.4.100.60 Software

7.0.98.0 or later 7.0 releases

You can upgrade directly to 7.4.100.60

Note If you have VLAN support and VLAN mappings defined on H-REAP access points and are currently using a 7.0.x controller software release that is prior to 7.0.240.0, we recommend that you upgrade to the 7.0.240.0 release and then upgrade to 7.4.100.60 to avoid losing those VLAN settings.

7.1.91.0

You can upgrade directly to 7.4.100.60

7.2. or later 7.2 releases

You can upgrade directly to 7.4.100.60

Note If you have an 802.11u HotSpot configuration on the WLANs, we recommend that you first upgrade to the 7.3.101.0 controller software release and then upgrade to the 7.4.100.60 controller software release.

You must downgrade from the 7.4.100.60 controller software release to a 7.2.x controller software release if you have an 802.11u HotSpot configuration on the WLANs that is not supported.

7.3 or later 7.3 releases

You can upgrade directly to 7.4.100.60


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 7.4.100.60 from an earlier release, you must also upgrade to Cisco Prime Infrastructure 1.3 and MSE 7.4.

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.

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

Ensure that your TFTP server supports files that are larger than the size of the controller software release 7.4.100.60. 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 7.4.100.60 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 FlexConnect Configuration Guide.


Note Predownloading a 7.4.100.60 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 7.4.100.60 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

Step 21 If you have disabled the 802.11a/n and 802.11b/g/n networks in Step 4, reenable them.

Step 22 To verify that the 7.4.100.60 controller software is installed on your controller, click Monitor on the controller GUI and look at the Software Version field under Controller Summary.


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.

Open Caveats

Table 5 lists the open caveats in the 7.4.100.60 controller software release.

Table 5 Open Caveats

ID
Description

CSCto02968

Symptom: Slow memory leak observed on a controller doing web authentication. Also, custom web page changes every 20 minutes.

Buffer allocation for 64 pool goes very high in a few days.

Follow up for CSCtl71583, as at least one leak is not yet fixed.

This affects the 7.2 and later controller software releases only for IPSec and some CPU ACL scenarios.`

Workaround: Reboot the controller.

CSCug86566

Symptom: Upon downgrading from the 7.4.100.60 to the 7.3.112.0 controller software release, the following errors are observed on controller console:

readCPUConfigData: cardid 0x6070001
xml_mask_and_compare_with_value failed for node 
ptr_aclCfgData.aclTable.list.bitmask, masked value = 8, value = 0

xml_mask_and_compare_with_value failed for node 
ptr_aclCfgData.aclTable.list.bitmask, masked value = 8, value = 0
Validation for node ptr_aclCfgData.aclTable.list.action failed, indices 
for node are 1 64 
Cisco is a trademark of Cisco Systems, Inc.

Conditions: Downgrade.

Workaround: No functionality impact detected; configuration seems to be the same.

CSCub24389

Symptom: Cisco 5508 controller stops responding using LSC with multiple APs (AP3500 and AP1131)

Conditions: Stack Trace:

lwapp_client_process(0x58679c)+0x418 [0x001A5AF0] 
process_execute(0x1a5964)+0x18c

Workaround: Disable LSC on the controller.

CSCub63054

Symptom: VLAN Transparent enabled on a 7.2 controller software release does not pass VLAN tags. Span at the end device shows all frames being placed on the native VLAN.

Conditions: VLAN Transparent enabled.

Workaround: Disable VLAN Transparent and set the MAP Ethernet port as trunk.

CSCuc02149

Symptom: A 3600 series AP in either autonomous IOS or FlexConnect local switching mode drops IP6to4 TCP SYN ACK packets that are received from its LAN

port.

A wired sniff at the AP port shows, when the wireless client attempts to establish a TCP connection over IPv6 in IPv4, that the AP transmits the TCP SYN (in IPv6 in IPv4) to the switch, and receives the SYN+ACK from the switch, but fails to forward the SYN+ACK packet to the wireless client.

The first time that the AP, after a reload, drops the SYN+ACK packet, the following message is displayed on the AP console, or in its log file:

WARNING - Received pak from RXTX port - Check log for detailed info

At the same time, the wireless client can successfully ping the IPv6 address of its 6to4 gateway.

Conditions: A 3600 or 2600 series AP, in autonomous or FlexConnect local switching mode.

Wireless client is attempting to establish TCP connections over IPv6 in IPv4, that is IPv4 protocol type 41.

Workarounds:

Use a AP1040, AP1140, AP1260, or AP3500

Disable IPv6 support on the application server

If you are using lightweight mode, use a centrally switched WLAN rather than a locally switched one.

CSCuc06605

Symptom: AP1142 r0 core dump: incorrect rcv pak pointer

Workaround: None.

CSCuc99675

Symptom: AP802 might fail to change to FlexConnect mode.

Conditions: AP802 in local mode

Workaround: None.

Note This is random issue, under investigation.

CSCud16350

Symptom: Apple iPhone and Apple iPad have intermittent connectivity issues with WPA2 and Cisco OEAP

Conditions: WPA2

Workaround: None.

CSCud22588

Symptom: Traceback and message log flood with messages such as the following:

*mmListen:   osapi_sem.c:1077 Failed to release a mutual exclusion 
object. mutex unlock failed, not owned by the calling thread.

Conditions: IPv6 enabled in the controller.

You do not need IPv6 to be enabled on your wired network to see these error messages but this is coming from wireless clients that are IPv6 or IPv4 capable.

These are cosmetic messages.

Workaround: Disable IPv6 if IPv6 is not needed.

CSCud23648

Symptom: Controller with the 7.3.101.0 software release stops responding.

Conditions:

Task Name: osapiReaper

User case: The system encountered a fatal condition at broffu_fp_dapi_cmd.c:3679

Workaround: None.

CSCud39329

Symptom: Controller 5500 on a 7.3 software release stopped working.

Conditions: Task SXP SOCK

Workaround: None.

CSCud41334

Symptom: Ethernet bridged client of a MAP does not work.

Conditions: If the Ethernet bridged client has been plugged into the Ethernet port of a MAP before MAP joins the controller, the client will not work. The issue is seen on AP1140, AP3500, and AP3600 (all indoor MAPs). The issue is not seen on AP1552 (outdoor MAP).

Workaround: Ensure that the bridged client is not plugged into the MAP Ethernet port and then reboot the MAP. Let MAP associate with the controller before plugging the client into the MAP Ethernet port. The client should get a valid IP address and should respond to pings.

CSCud41398

Symptom: With some specific clients (currently observed with only Android phones and Apple iPads), during downstream traffic, sometimes traffic flow is affected. The AP continuously transmits the same packets to the client even though the client has acknowledged. Only when the packet is transmitted as non-aggregate, the packet is successfully done from the AP end; all the aggregate packets are repeatedly transmitted.

Conditions: This occurs only for downstream traffic with specific clients under BA exchange.

Workaround: Disable aggregation.

CSCud63437

Symptom: Unplanned reboot on HA scenario after active reboot.

Conditions: Network failover option is enabled. Low frequency issue.

Workaround: None.

CSCud84135

Symptom: An access point upgraded to autonomous IOS 15.2(2)JB release has no IP connectivity to devices that are outside its local subnet.

Conditions: Access point is using autonomous IOS 15.2(2)JB release, but does not have a default route configured.

Note This is not an issue for lightweight IOS, which automatically install a default route to BVI1 if the default route is missing.

Workaround:

1. Configure a default route. For example:

ip route 0.0.0.0 0.0.0.0 <default-gateway-address>

or

ip route 0.0.0.0 0.0.0.0 BVI1

2. Disable IP routing.

3. If the AP gets its address from a DHCP server, configure a default gateway for the AP's scope in DHCP.

Further Problem Description: In the 15.2(2)JA and earlier AP IOS software releases, `no ip routing' was in effect. In this mode, the AP does ARP for all IP addresses if it does not have a default-gateway configured. In the 15.2(2)JB AP IOS release, `ip routing' is enabled by default; in this mode if the AP does not have a default route, it drops traffic that is addressed to other networks.

CSCud97325

Symptom: AP3600 and AP2600 send invalid frames sourced with the 0000.0104.xxxx address. This might result in security warnings on the switch such as the following:

%AUTHMGR-5-SECURITY_VIOLATION: Security violation on the interface 
GigabitEthernet3/46, new MAC address (0000.0104.d634) is seen.

Conditions: This occurs when the primary or the secondary controller is changed in the AP High Availability tab. This issue is seen only with Cisco Aironet 2600 and 3600 Series Access Points.

Workaround: None.

CSCue00164

Symptom: Standby unplanned reboot after mesh AP joins active controllers.

Conditions: HA and mesh are in use.

Workaround: Mesh APs are not supported on HA.

Further Problem Description: Fix will prevent the incorrect handling of mesh AP information.

CSCue08874

Symptom: Tx power level is stored in the AP configuration file and has to be remembered after reboot. For AP1600, AP2600, AP3600, and the 802.11ac module, when the Tx power level is changed, say from level 1 to 4, then if AP is rebooted once or twice, the Tx power level goes back to 1.

Conditions: STATIC Tx power level reset to 1 after several reboots of the AP.

Workaround: Do not use STATIC Tx power for AP or do not reboot the AP. If changed, reconfigure the power.

CSCue09354

Symptom: Rogue AP does not get detected on wired when it is on a nonnative VLAN trunk to rogue detector AP.

Conditions: 7.4.100.0 controller software release with rogue detector mode AP. Rogue AP not on rogue detector native VLAN.

Workaround: None.

CSCue32755

Symptom: Wireless clients are unable to associate with mesh APs.

Conditions: Wired clients go down, connected to the mesh AP that has Ethernet bridging enabled.

Workaround: Reboot the mesh AP for the wired and wireless clients to associate.

CSCue34072

Symptom: Controller experiences leaking memory for task:mmlisten.

Conditions: Unknown.

Workaround: None.

CSCue51812

Symptom: Clients do not associate with the best serving AP; clients are observed to gain network access and roam relatively frequently.

Conditions: Band Select enabled, default parameters or with less aggressive values (1 probe cycle, 100 ms suppression window).

Workaround: Disable Band Select in high density environments.

CSCue55397

Symptom: Controller completes upgrade successfully, but the AP fails to do so. There are no errors except for APs failing to upgrade, and the corresponding syslog errors due to CAPWAP image request failure.

This occurs on a high percentage of controllers.

Conditions: Controller on a high load.

Workaround: Reinstall controller software with no APs connected.

CSCue80531

dBm value is zero for AP802

CSCue97090

Standby controller reboots with GW not reachable with a backup port configured

CSCue99040

Cisco Flex 7500 and Cisco WiSM2 controllers have High Availability issues

CSCuf02268

HA controllers do not pair with 80ms RTT

CSCuf03309

Symptom: RDP sessions are timing out (no setup completed). Ping works. Moving client to another AP or VLAN solves the issue.

Conditions: Cisco WiSM2 with DTLS enabled.

Workaround: Disable DTLS.

CSCuf15633

Symptom: Unexpected controller reboot might happen when the config wlan delete command is entered.

Conditions: The command is entered with multicast settings in place.

Workaround: Use controller GUI to delete WLAN.

CSCuf35269

Symptom: 802.11u domain is lost after a controller reboot.

Conditions: Same domain name is used on two different WLANs. This is allowed on controller CLI, but configuration validation fails on bootup.

Workaround: Reconfigure the domain, or use different domain names.

CSCuf80340

Symptom: Internal web authentication is not working in virtual controller.

Conditions: Cisco virtual controller.

Workaround: None.

Further Problem Description: Web authentication is a Layer 3 security feature that causes the controller to disallow IP traffic (except DHCP and DNS -related packets) from a particular client until that client has correctly supplied a valid username and password. It is an authentication method without the need for a supplicant or client utility. Web authentication is typically used by users who want to deploy a guest-access network. Typical deployments can include HotSpot locations such as T-Mobile or Starbucks.

CSCuf86303

Symptom: Controller stops responding with the following message displayed:

The system has encountered a fatal condition at 
broffu_fp_dapi_cmd.c:3820" and DP crashed with DP exception.

Conditions: This occurs when the controller is receiving multicast traffic at a very high rate.

Workaround: None.

CSCuf93738

Symptom: It looks like the running configuration is correct as everything is working as expected and the show run-config command shows the correct configuration. However, if the configuration file .cfg is exported and opened, it is found that some AP groups reflect an old interface mapping that no longer exists, even if the configuration was saved.

Conditions: Cisco 5508 controller using the 7.0.230.x software release. AP groups are in use with interface mappings. A WLAN to interface mapping is present and the interface is renamed using Cisco Prime Infrastructure.

Workaround: Delete the AP group and create a new one.

CSCuf93777

Symptom: AP2600 and AP3600 fail with radio reset generating a core dump.

Conditions: Monitor mode APs with active RLDP.

Workaround: Disable RLDP.

CSCug04801

Symptom: After a couple of switchovers, none of the clients gets authenticated.

Conditions: This is seen on doing a few failovers with 2000 802.1X authenticated clients with Cisco WiSM2 in an HA configuration.

Workaround: None.

CSCug08318

Symptom: Controller stops responding in an HA scenario.

Conditions: Very large user count; low frequency issue; under investigation.

Workaround: None.

CSCug10935

Symptom: Primary controller and secondary controller configured as HA SSO and ACL is configured for clients. When the primary controller is down, the ACL is not inherited to the secondary controller after the switchover so that the client can access the previously restricted information.

Condition: Unknown.

Workaround: None.

CSCug10985

Symptom: After a software release upgrade, the standby controller might reboot twice during configuration synchronization.

Conditions: HA enabled.

Workaround: None.

Impact is limited, standby controller works after configuration synchronization.

CSCug14709

Symptom: In a 7.4 controller software release, the controller does not take into account anymore if `airespace wlan-identifier' attribute is sent back in access-accept by the RADIUS server.

Conditions: This used to work in the 7.0.x release but does not work in the 7.4 release. It is not known whether this issue affects the 7.2 and the 7.3 releases.

Workaround: Use another mechanism to restrict SSID access.

CSCug15064

Symptom: Controller goes into maintenance mode with HA enabled, if primary port is down.

Conditions: Cisco Flex 7500 and Cisco 8500 series controllers; non-LAG scenario; backup port is configured and primary port is down.

Workaround: None.

CSCug16473

Symptom: Controller using the 7.4.100.0 software release stops responding. With the previous controller software releases, the controller works as expected.

The messages on the console during this failure is similar to the following:

broffu broffu_fp_helpers.c:294 SIOCGIFINDEX failed
broffu_dtl0_create: SYSTEM-REBOOTING:could not bring data plane 0

Conditions: Console cable is connected.

Workaround: Remove the console connection during bootup.

CSCug21037

Symptom: Standby controller stops responding when active controller starts to upgrade to a new software release.

Conditions: Upload the software release to the active controller. The software release is upgraded successfully on the standby controller. Upload another software release to the active controller and the standby controller might stop responding.

Workaround: Do not perform two software release upgrades in a row to the active controller.

CSCug22648

Symptom: WSSI module might not come up on some AP regulatory domain types.

Conditions: AP3600 using regulatory domain different from -A, -E.

Workaround: None.

CSCug23395

Symptom: Active controller might stop responding during operation, passing the control to the standby controller.

Conditions: MSE is in use; rogue location is enabled.

Workaround: Disable location for rogues.

CSCug29258

Symptom: FlexConnect mode AP with ACL is no longer filtering traffic.

Conditions: Apply ACL to the FlexConnect AP. If the AP reboots while it is in standalone mode, the ACL might no longer be applied. It works if AP is in connected mode.

Workaround: Connect AP to the controller.

CSCug41333

Symptom: AP with DTLS encryption enabled is disconnecting every 73 seconds.

Conditions: DTLS encryption; default gateway MAC address has changed.

Workaround: Prevent change of router MAC address.

CSCug42330

Symptom: Interface ACL on the controller might incorrectly apply on all the interfaces even on the one it is not applied on.

Conditions: Controller using 7.0 to 7.3 software releases.

Workaround: None.

CSCug45057

Symptom: 2.4-GHz and 5-GHz radios are disabled due to "Radio disabled due to inline power" error.

Conditions: Upgrade to 7.4.100.0

Workaround: None.

CSCug48432

Symptom: With HA configured and after the secondary controller reboots, the secondary controller goes into maintenance mode.

The reason to go to maintenance mode is communication down.

We see the interface configuration gets lost on the secondary controller after reboot and it is found that there is no connectivity.

Conditions: HA configured.

Workaround: None.

CSCug57216

Symptom: Ascom phone stops receiving voice packets.

Conditions: 802.11n in use; voice traffic QoS markings are lost in downstream direction.

Workaround: Either fix QoS markings or disable 802.11n.

CSCug64750

Symptom: Traffic disruption on some specific devices (Apple) while on L3 roaming state.

Conditions: ARP unicast generated by client, dropped by foreign controller. Client on mobile state.

Workaround: None.

CSCue04528

Symptom: Controller stops responding on osapiBsnTimer task.

Conditions: Cisco TrustSec SXP is enabled. HA is in use.

Workaround: Either disable SXP or the HA features.

CSCug70229

Symptom: Web authentication fails for static IP client on export anchor or on foreign controller.

Conditions: Unknown.

Workaround: None.

CSCue91018

Symptom: SSID column in raw report from the controller shows incorrect data.

Conditions: When netflow record is sent from the controller.

Workaround: Use the same name for WLAN profile and WLAN SSID.

CSCug26521

Symptom: A controller using the 7.4 software release and option 82 with DHCP proxy enabled.

It is found that the option 255 is missing in the DHCP request packets sent out by the controller thus resulting in packet being dropped during inspection.

Conditions: 7.4 controller software release.

Workaround: Set format to ASCII by entering this command:

config dhcp opt-82 format ascii

By default, the format is binary. Therefore, option 82 does not work.

CSCug73845

Symptom: Controller NAS ID override is taking system name instead of the NAS ID that is configured on the AP group/WLAN/Interface.

Conditions: Configure AP group/WLAN/Interface NAS ID.

Workaround: None.

CSCug18190

Symptom: After clearing configuration and rebooting the controller, if you configure HA again, the MAC address might be shown as different when you enter the show mobility summary command.

Conditions: Configuration cleared.

Workaround: This does not occur in a normal scenario, unless a full configuration wipe and reconfiguration process is done, and HA is reestablished.

CSCug65454

Symptom: Controller may stop responding with a reason of Reaper Reset: Task "dtlArpTask" missed software watchdog.

Workaround: None.

CSCug54108

Symptom: AP memory leak causes SSH (to AP) to fail.

Conditions: SSH to AP does not work.

Workaround: Reboot the AP.

CSCuf30537

Symptom: RADIUS CalledStationID attribute is not consistent between web authentication and 802.1X authentication processes.

Conditions: RADIUS server checking MAC address in CalledStation ID.

Workaround: None.

CSCud72601

Symptom: Ascom i62 phones start to do full authentication while roaming when the WLAN session timeout expires.

Conditions: WLAN session timeout is configured and it expires. The client does a reauthentication with a new PMK.

Workaround: Disable session timeout on the WLAN.

CSCud33577

Symptom: FlexConnect AP does not work as expected.

Conditions: When FlexConnect AP cannot renew DHCP lease, the BVI1 interface goes down.

Workaround: Reboot the AP or increase lease time to a higher value. You can also use static IP addresses on the AP.

Create a VLAN 1 from the FlexConnect group.

Further Problem Description: This issue is not seen if the native VLAN on the FlexConnect AP is set to 1.

Installation Notes

This section contains important information to keep in mind when installing controllers and access points.

Warnings


Warning This warning means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device. Statement 1071

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

Warning Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, as they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.: NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 280

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). Statement 13

Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground connector. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Warning Read the installation instructions before you connect the system to its power source. Statement 10

Warning Do not work on the system or connect or disconnect any cables (Ethernet, cable, or power) during periods of lightning activity. The possibility of serious physical injury exists if lightning should strike and travel through those cables. In addition, the equipment could be damaged by the higher levels of static electricity present in the atmosphere. Statement 276

Warning Do not operate the unit near unshielded blasting caps or in an explosive environment unless the device has been modified to be especially qualified for such use. Statement 364

Warning In order to comply with radio frequency (RF) exposure limits, the antennas for this product should be positioned no less than 6.56 ft. (2 m) from your body or nearby persons. Statement 339

Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017

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.
