Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide, Cisco IOS XE Dublin 17.11.x

AP Crash File Upload

When a converted access point unexpectedly reboots, the access point stores a crash file on its local flash memory at the time of the crash. After the unit reboots, it sends the reason for the reboot to the device. If the unit rebooted because of a crash, the device pulls up the crash file using the existing CAPWAP messages and stores it in the device flash memory. The crash information copy is removed from the access point's flash memory when the device pulls it from the access point:

Note

The system does not generate reports in case of a reload.

During a process crash, the following are collected locally from the device:

Full process core
Trace logs
Cisco IOS syslogs (not guaranteed in case of nonactive crashes)
System process information
Bootup logs
Reload logs
Certain types of proc information

All this information is stored in separate files, which are then archived and compressed into one bundle. This makes it convenient to get a crash snapshot in one place, and can be then moved off the box for analysis. This report is generated before the device goes down to ROMMON/bootloader.

Note

Except for the full core and tracelogs, everything else is a text file.

Configuring AP Crash File Upload (CLI)

Procedure

Step 1	enable Enters privileged EXEC mode.
Step 2	ap name `ap-name` crash-file get-crash-data Collects AP crash information. The crash file is uploaded automatically after the AP reloads to ready state. Therefore, this command does not have to be manually executed.
Step 3	ap name `ap-name` crash-file get-radio-core-dump slot {0 \| 1} Collects the AP core dump file for slot 0 or slot 1.
Step 4	ap name `ap-name` core-dump `tftp-ip` `crash-file` uncompress Uploads the AP crash coredump file to the given TFTP location.
Step 5	show ap crash-file Displays the AP crash file, as well as the radio crash file.
Step 6	dir bootflash Displays the crash file in bootflash with .crash extension.

Information About LED States for Access Points

In a wireless LAN network where there are a large number of access points, it is difficult to locate a specific access point associated with the controller. You can configure the controller to set the LED state of an access point so that it blinks and the access point can be located. This configuration can be done in the wireless network on a global as well as per-AP level.

The LED state configuration at the global level takes precedence over the AP level.

Note

For APs that have Ethernet LEDs in addition to the main system LED, the Ethernet LEDs are enabled or disabled (switched ON or OFF) as per the system LED. For example, if the system LED is ON, the Ethernet LED will also be ON.

Configuring LED State in Access Points (GUI)

Procedure

Step 1	Choose Configuration > Wireless > Access Points.
Step 2	Click an AP from the AP list. The Edit AP window is displayed.
Step 3	In the General tab, under the General section, go to LED Settings. Click the box adjacent to the LED State field to enable or disable the LED state. From the LED Brightness Level drop-down list, choose a value from 1 to 8.
Step 4	Under the Flash Settings section, perform the following steps: Click the box adjacent to the Flash State field to enable or disable the flash state. When the flash state is enabled, the current status of the flash and the flash duration fields are displayed. From the Flash Duration drop-down list, choose either Always ON or Timed. If you choose the Timed option, the Time Duration field is displayed. In the Time Duration field, specify the flash duration time, in seconds. The default value is one second. The valid range is between 1 second and 3600 seconds.
Step 5	Click Update & Apply to Device.

Access Point Support Bundle

An access point (AP) support bundle contains core files, crash files, show run-configuration , configuration commands, msglogs, and traplogs.

This topic describes how you can retrieve the support bundle information of an AP and export it to the controller or to an external server. (Until Cisco IOS XE, Release 17.2.1, you had to log in to the AP console to retrieve the AP support-bundle information.)

The Access Point Support Bundle feature is supported only on Cisco Wave2 APs and Cisco Catalyst APs.

Exporting an AP Support Bundle (GUI)

Procedure

Step 1

Choose Configuration > Wireless > Access Points.

Step 2

Click the corresponding AP name.

The Edit AP window is displayed.

Information About Access Point Tag Persistency

From Cisco IOS XE Bengaluru 17.6.1 onwards, AP tag persistency is enabled globally on the controller. When APs join a controller with tag persistency enabled, the mapped tags are saved on the APs without having to write the tag configurations on each AP, individually.

Configuring AP Tag Persistency (GUI)

Procedure

Step 1	Choose Configuration > Tags & Profiles > Tags.
Step 2	Click the AP tab.
Step 3	In the Tag Source tab, check the Enable AP Tag Persistency check box to configure AP Tag persistency globally. When APs join a controller with the tag persistency enabled, the mapped tags are saved on the AP without having to write the tag configurations on each AP individually.
Step 4	Click Apply to Device.

What to do next

Save tags on an AP.

Saving Tags on an Access Point (GUI)

Procedure

Step 1	Choose Configuration > Wireless > Access Points.
Step 2	Click an AP from the list. The Edit AP page is displayed.
Step 3	Click the General tab.
Step 4	In the Tags section, specify the appropriate policy, site, and RF tags that you created in the Configuration > Tags & Profiles > Tags page.
Step 5	From the Policy drop-down list, select a value.
Step 6	From the Site drop-down list, select a value.
Step 7	From the RF drop-down list, select a value.
Step 8	Check the Write Tag Config to AP check box to push the tags to the AP so that the AP can save and remember this information even when the AP is moved from one controller to another.
Step 9	Click Update & Apply to Device.

Deleting Saved Tags on the Access Point

Procedure

Step 1	Choose Configuration > Wireless > Access Points.
Step 2	Click an AP from the list of APs. The Edit AP window is displayed.
Step 3	In the Edit AP window, choose the Advanced tab.
Step 4	In the Set to Factory Default section, check the Clear Resolved Tag Config check box to clear the saved tags on an AP.
Step 5	Click Update & Apply to Device.

Configuring AP Tag Persistency (CLI)

Before you begin

For an AP to preserve its policy tag, site tag, and RF tag configured from the primary controller, these tags must also exist on the other controllers that the AP connect to. If all the three tags do not exist, the AP applies the default policy tag, site tag, and RF tag. Similarly, the tag policy is applicable even if one or two tags exist. AP tag persistency helps in priming an AP in N+1 redundancy scenarios. For more information about configuring tags, see https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/17-6/config-guide/b_wl_17_6_cg/m_config_model.html.

Note

After being enabled, AP tag persistency is performed during AP join. Therefore, if there are any APs that are already joined to the controller, those APs must rejoin the controller.

Procedure

Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

ap tag persistency enable

Example:

Device(config)# ap tag persistency enable

Configures AP tag persistency.

Step 3

end

Example:

Device(config)# end

Exits configuration mode and returns to privileged EXEC mode.

Verifying AP Tag Persistency

To verify AP tag persistency in the primary controller, use the following command:

Device# show ap tag summary
Number of APs: 1

AP Name         AP Mac           Site Tag Name         Policy Tag Name        RF Tag Name            Misconfigured    Tag Source
--------------------------------------------------------------------------------------------------------------------------------
Cisco01_AP      xxxx.xxxx.xxxx   default-site-tag      OpenRoaming            default-rf-tag         No               Static

Note

If the Tag Source displays Static or Filter, it means that the AP tag mappings were configured on the primary controller. If the source displays Default, it means that the AP received the default tags when joining the controller.

To verify the AP tag persistency in the secondary controller, use the following command:

Device# show ap tag summary
Number of APs: 1

AP Name       AP Mac           Site Tag Name        Policy Tag Name     RF Tag Name       Misconfigured   Tag Source
--------------------------------------------------------------------------------------------------------------------
Cisco01_AP   xxxx.xxxx.xxxx    default-site-tag     OpenRoaming         default-rf-tag     No              AP

Note

If the Tag Source displays AP, it means that the policy tag, site tag, and RF tag match what was configured on the primary controller, indicating that the AP tags have persisted across controllers.

Feature History for AP Power Save

This table provides release and related information for the feature explained in this module.

This feature is also available in all the releases subsequent to the one in which they are introduced in, unless noted otherwise.

Table 1. Feature History for AP Power Save
Release	Feature Information
Cisco IOS XE Cupertino 17.8.1	This feature allows a network administrator to force APs to operate in low-power mode to reduce power consumption.
Cisco IOS XE Cupertino 17.9.1	Feature support for the following APs: Cisco Catalyst 9164 Series Access Points Cisco Catalyst 9166 Series Access Points
Cisco IOS XE Dublin 17.10.1	The following features are supported: Radio spatial streams Flexible PoE profiles
Cisco IOS XE 17.13.1	AP Power Distribution support in Cisco Catalyst 9124 Series APs.

Information About AP Power Save

The power-save mode in APs allows a network administrator to force APs to operate in low-power mode to reduce power consumption.

The AP Power Save feature is supported in the following APs:

Cisco Catalyst 9115 Series Access Points
Cisco Catalyst 9120 Series Access Points
Cisco Catalyst 9124 Series Access Points
Cisco Catalyst 9130 Series Access Points
Cisco Catalyst 9136 Series Access Points
Cisco Catalyst 9164 Series Access Points
Cisco Catalyst 9166 Series Access Points
Cisco Catalyst 9162 Series Access Points

Access Point Power Policy

The access point power policy allows you to define the power budget utilization available for an AP, wherein, you can define a set of policies for different interfaces on an AP. You can manage interfaces such as Wi-Fi radios, USB, and so on, as required.

Cisco Catalyst 9124 AXI/D APs support up to two radio interfaces (single 5 GHz), and Cisco Catalyst 9124 AXE APs support up to three (dual 5 GHz) radio interfaces. When Cisco Catalyst 9124 Series APs operate under 802.3at/PoE+/30W insufficient power condition, the new operating modes support both dual or Tri-Radio mode.

Use Case for AP Power Policy

The following is the use case of an AP power policy:

You can define a power policy for the available power inputs, such as, 802.3af, 802.3at, 802.3bt (for multiple levels), DC power, and so on. With tri-radio and quad-radio APs, the power requirement has gone beyond the capability of the 802.3at Power over Ethernet (PoE) mode. Therefore, with the AP power policy, for example, we statically predefine an AP operation when provided with non-802.3bt power (such, as TX power, radio chains, USB port, SFP, and so on).

Power-Save Mode

The power-save mode enables an AP to switch to a low-power mode when no clients are associated with the AP. For example, when this mode is enabled in workspaces, the AP falls asleep during after hours, thereby saving power consumption of the AP throughout the night.

From Cisco IOS-XE Cupertino 17.10.1 onwards, you can shut down AP radios or lower the radio spatial streams, to reduce usage of power. You can enforce radio speed by configuring the number of spatial streams on the radios. The combinations for radio spatial stream policies are: 1X1, 2X2, 3X3 (only for Cisco Catalyst 9130 Series Access Points), 4X4, and 8X8.

The following are the advantages of the power-save mode:

Increases the energy saving per AP: In the power save mode you can reduce AP functions during off-peak hours and save an additional 20% in energy costs compared to the regular idle mode.
Enables environmentally conscious purchases: Large enterprises and companies track environmental performance as one of their key indices. They have a centralized energy team to monitor their energy efficiency, which magnifies the importance of the power-save feature.

PoE Profiles

Fixed PoE Profile: The APs negotiate the power that is required, from the switches they are connected to. The power required varies from one AP model to another AP model. If an AP is not granted the power it requested, it operates under the power budget. In such conditions, some of the interfaces operate under degraded conditions.

For example, some radios may operate at 2SS instead of at 4SS, which they are capable of. The operating conditions for each of the AP interfaces differs from one power level to another. These are referred to as fixed PoE profiles. Fixed PoE profiles are applied when the AP is operating in normal mode, that is, nonpower-save mode. When the AP operates in power-save mode, the configured PoE power policies are applied.
PoE Power Policy: With power policies or profiles, you can configure interfaces that you want to set at certain speeds. With this policy, you can configure a profile of your choice that will be pushed to the AP based on your calendar or timing. For example, on a group of APs in the second floor, push a profile where you want to turn off all APs, except 2.4-GHz radio, from 7 p.m. to 7 a.m.
Flexible PoE Profile: With flexible PoE profiles, you can configure different interfaces and set specific parameter values and states for each interface, instead of following fixed PoE profile rules. If an AP does not get the power it requires, it operates under the power budget by using the flexible PoE profile.

In Cisco IOS XE 17.13.1, PoE-out is a new interface introduced in Cisco Catalyst 9124 Series APs, in addition to the USB, Ethernet, and LAN interfaces. The PoE-out for Cisco Catalyst 9124 Series AP RLAN works only if you have enabled the RLAN port.

Wakeup Threshold for Access Point Power Save Mode

The Wakeup Threshold feature enables you to define the client threshold in the AP power profile configuration to determine when the AP wakes up from the power save mode or enter into the power save mode.

When the AP applies the calendar associated power profile (for an active calendar), and the number of connected clients reach the wakeup threshold, the AP wakes up from power save mode and goes into the Fixed power profile mode or the Regular power profile (insufficient power) mode.

When the AP applies the calendar associated power profile (for an active calendar), and the number of connected clients is less than the wakeup threshold, the AP applies the calendar associated power profile to shut down the interface or to lower the interface speed to save power.

AP Power Save Scenarios

The AP Power Save feature helps APs to enter into a power-save mode or low-power mode by applying a calendar, for example, for after hours, associated with the corresponding power profile. The AP profile is enhanced to associate a PoE power policy with calendar profiles. The following are the scenarios for Eco mode APs:

Figure 1. AP in Eco Mode Behavior: Working Days

On working days, from 7:00 a.m. to 7:00 p.m, the AP functions in normal mode or fixed mode, when the maximum number of clients are connected to the AP. From 7:00 p.m. to 12:00 a.m., the Cal1 calendar profile timer starts to put the AP in the power-save mode. Likewise, the Cal2 calendar profile timer starts, and extends the power-save mode from 12:00 a.m. to 7:00 a.m. Again, at 7:00 a.m., the AP goes into normal mode.
Figure 2. AP in Eco Mode Behavior: Nonworking Days

On nonworking days, the AP goes into power-saving mode from 12:00 a.m. to 11:59:59 p.m. The Cal3 calendar profile is applied here. This profile defines the timer for the power-save mode. This means that there are no clients connected to the AP, and that the AP is asleep.
Figure 3. AP in Eco Mode Behavior: With Clients

When clients are connected to the AP, the AP automatically switches to the normal mode. For example, in the calendar profile Cal1, the AP is in normal mode, because wireless clients are connected to the AP. At 8:00 p.m., clients get dissociated from the AP, and the AP goes into power-save mode. When clients enter the AP coverage area at 9:30 p.m., the AP automatically switches from power-save mode to normal mode of operation.

Configuring Power Policy Profile (GUI)

Procedure

Step 1	Choose Configuration > Tags & Profiles > Power Profile.
Step 2	Click Add. The Add Power Profile window is displayed.
Step 3	Enter a name and description for the power profile. The name must be ASCII characters of up to 128 characters, without leading or trailing spaces.
Step 4	Click Add to add rules for the power profile.
Step 5	In the Sequence number field, enter a unique sequence number to designate the priority in which power should be disabled for the component. The sequence number of 0 indicates that the component should be disabled first.
Step 6	From the Interface and Interface ID drop-down list, choose interface and interface ID to designate to the component for which the power derating rule applies.
Step 7	From the Parameter and Parameter value drop-down list, choose the values depending on the interface you chose in step 6. For example, if you chose Ethernet as an interface, you can further customize the rule for the interface by choosing the associated speed. This rule ensures that the AP disables power for the Ethernet interface that is operating at a higher speed, and thereby consuming more power.
Step 8	Click the check mark to save and then click Apply to Device.

Information About Access Point Real-Time Statistics

From Cisco IOS XE Bengaluru 17.5.1 onwards, you can track the CPU utilization and memory usage of an AP, and monitor the health of an AP, by generating real-time statistics for an AP.

SNMP traps are defined for CPU and memory utilization of APs and the controller. An SNMP trap is sent out when the threshold is crossed. The sampling period and statistics interval can be configured using SNMP, YANG, and CLI.

Statistics interval is used to process the data coming from an AP, and the average CPU utilization and memory utilization is computed over time. You can also configure an upper threshold for these statistics. When a statistic value surpasses the upper threshold, an alarm is enabled, and an SNMP trap is triggered.

From Cisco IOS XE Cupertino 17.7.1 release onwards, for radio monitoring, you can reset the radios based on the statistics sent by the AP for a sampling period. When you configure the radios in the controller, if there is no increment in the Tx or Rx statistics when the radio is up, then the radio reset is triggered.

Cisco IOS XE Cupertino 17.7.1	Real Time Access Point Statistics	This feature is enhanced with the implementation of AP threshold values between 0 and 50 to trigger an alarm.

Restrictions for AP Radio Monitoring Statistics

You cannot reset the radio firmware from the controller. The controller will shut and unshut the radio if the Rx or Tx count is not incremented for a radio slot in a specified period.

Configuring Access Point Real Time Statistics (GUI)

Procedure

Step 1	Choose Configuration > Tags & Profiles > AP Join.
Step 2	Click Add. The Add AP Join Profile page is displayed.
Step 3	Under the AP tab, click the AP Statistics tab.
Step 4	In the System Monitoring section: Enable Monitor Real Time Statistics to get calculated statistics and alarms of the AP. To receive an alarm when the upper threshold is surpassed for parameters such as CPU utilization and memory, enable Trigger Alarm for AP. Enter the threshold percentage for CPU and memory usage in the CPU Threshold to Trigger Alarm field and Memory Threshold to Trigger Alarm fields, respectively. The valid range is between 0 to 50. An SNMP trap is sent out when this threshold is crossed. In the Interval to Hold Alarm field, enter the time for which the alarm is held before it gets triggered. The valid range is between 0 and 3600 seconds. In the Trap Retransmission Time field, enter the time between retransmissions of the alarm. The valid range is between 0 and 65535 seconds. To define how often data should be collected from the AP, enter a value in the Sampling Interval field. The valid range is between 720 and 3600 seconds. To define the interval at which AP statistics are to be calculated, enter a value in the Statistics Interval field. The valid range is between 2 and 900 seconds. To automatically reload the AP when there is high CPU and memory usage in the defined sampling interval, select the Reload the AP check box.
Step 5	Under the Radio Monitoring section: Select the Monitoring of AP Radio stuck check box to verify that the Tx and Rx statistics of the AP are updated each time the payloads are coming in from the AP to the controller. To generate an alarm for the radio of the AP when there is no increment in the Tx and RX statistics for the payloads, select the Alarms for AP Radio stuck check box. Select the Reset the stuck AP Radio check box to recover the radio from the bad state. A radio admin state payload will be sent from the controller to toggle the radio and the radio will be shut when there is no increment in the Tx and Rx statistics. To define how often data should be collected from the radio, enter a value in the Sampling Interval field. The valid range is between 720 and 3600 seconds.
Step 6	Click Apply to Device to save the configuration.
