Although anchor is notified about the expired session and deletes the entries based on debugs, for some client entries, the session stales on the anchor. Those entries cannot be cleared and results in increased current session time. Workaround : Reboot the controller to clear the 'stale' entries. APs in Local mode reboot; watchdog timer expired.

Symptom : APs restart and return with the following message:. Symptom : When disabling data rates or changing a rate to mandatory, the output keyword from the show run-config commands contains an upper case letter, which the CLI parser does not accept. Conditions : The following output is displayed:. Workaround : Use the command in the following manner:. Symptom : On the output of the data rate commands, any changes in the mandatory rates should be output before disabled rates.

If the disabled commands disable all the mandatory rates, the final disable command is rejected until the new mandatory rate is set. Workaround : Configure in the following order:. Conditions : The DCA and band select commands are not displayed in the output of show run-config commands. Symptom : If RADIUS servers are assigned nonsequential index numbers, some of the output in the show run-config commands have the wrong index numbers.

Note The index number used on the final 3 lines are 1, 2, and 3 instead of 3, 4, and 5. Symptom : Some commands allow for imbedded spaces by including the parameter in quotes. The output from the CLI does not include the quotes. Therefore, the command is invalid. For example, wlan create and wlan apgroup add are such commands. Conditions : The following is the input:. Workaround : Manually add the quotes for names with spaces. The output of the show run-config commands does not include this prompt.

Conditions : For example, configuring an AP global syslog host. Workaround : Proceed without any confirmation. Symptom : Line-feeds are missing on some lines when you enter show run-config commands. The show client detail mac-addr command does not display client statistics values. Symptom : Only 6 Mbps rate is configured as mandatory on Controller allows creation of dynamic interfaces with overlapping subnet. Users must ensure that there are no multiple VLANs with overlapping subnets, which might cause issues with Layer 3 roaming of clients.

Controller unresponsive when executing the show ap eventlog ap-name command. Symptom : Controller reboots with crash file created while executing the show ap eventlog ap-name command. Symptom : Wired clients are unable to reach wireless clients due to receiving incorrect MAC information from the controller.

For example, This can be seen by entering the show arp switch command where the IP address of the wired client and VLAN are displayed. Conditions : Controller software release 7. Workaround : Reboot the controller. High parallel QoS traffic streams cause radio transmission watchdog resets and radio coredumps. Symptom : High parallel QoS traffic streams cause radio transmission watchdog resets and radio coredumps.

Problem receiving multicast on wireless clients on WiSM2. Symptom : Multicast and unicast traffic between controller and AP fails. Workaround : Changing the mode to "multicast-multicast" mode resolves the issue and further reverting to "multicast-unicast" mode also resolves the issue because this explicitly cleans the replication group tunnels to the DP.

Controller failed to bring up SXP connection with N7k. Controller secure password policies enforced for local net users on CLI. Symptom : Secure password policies, which are available for the management users, are invoked when changing the password for a local net user on the controller CLI. A local net user can be created with any username and password. Issue only occurs when you change the password. Use at least three of the following four classes in the password:.

Conditions : When changing the local net user password through the CLI. This issue is observed on all controller platforms running controller software releases 7. Workaround : Use the controller GUI to change the passwords for local net users. Cisco Series Controller unresponsive and then reboots after a successful upgrade from a 7.

Conditions : Upgrade from a 7. The controller became unresponsive after a client tried to associate with the controller and tried to do web authentication. Workaround : This issue is not reproducible. Conditions : Troubleshooting connectivity issues for clients. Workaround : Enable SSH and telnet during a maintenance window on all FlexConnect locally switched APs to avoid bouncing the radios causing connectivity issues during business hours.

Accounting traffic statistics counters are unreliable with web authentication. Conditions : Controller software releases 7. These clients are not reachable. Controller software Release 7. Conditions : This is not reproducible and is observed only on the customer site deployment.

Symptom : Web authentication on MAC filter failure; authentication sporadically fails. Workaround : To delete the ghost entry, the following options are available:. APs seen to dissociate from the controller when sysname is 31 characters long. Workaround : Restrict the controller system name length to 30 characters. Workaround : Use mesh security 'PSK'. Symptom : Controller unresponsive due to out of memory issue with logs such as the following:.

Conditions : Very high CPU utilization. Symptom : An SXP connection from the controller to the Cisco Nexus Series switch reports the On state on the controller side while the switch reports the Waiting for Response state.

This section contains important information to keep in mind when installing controllers and access points. 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 Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. 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. 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.

Warning Read the installation instructions before you connect the system to its power source. 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. 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. Warning In order to comply with radio frequency RF exposure limits, the antennas for this product should be positioned no less than 6.

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

Proper operation of this radio device according to the instructions in this publication results in user exposure substantially below the FCC recommended limits. For your safety, and to help you achieve a good installation, read and follow these safety precautions.

They might save your life! 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. 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. 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.
