AP Management

Access point crash files

A crash file is a diagnostic file that

  • is created when an AP experiences an unexpected reboot,

  • contains information about the state of the AP at the time of the crash, and

  • is stored in the local flash memory of the AP for retrieval.

AP crash files provide data that is essential for diagnosing the causes of unexpected reboots in access points. This data aids in troubleshooting and maintenance.

Process crash details

When a process crashes, the device collects various types of data. and compiles it into a single, compressed archive for analysis.

  • 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


Note

Except for the full core and tracelogs, everything else is a text file. This consolidated information provides a snapshot of the AP's state, which can be used for further diagnosis.

Limitations

Reports are not generated by the system in case of a reload.

Configure access point crash file upload process (CLI)

Set up and configure an access point to collect and upload crash files for diagnostics.

This involves configuring multiple data collection commands and ensuring files are available for troubleshooting access point failures.

Follow these steps to configure the AP crash file upload process:

Procedure

Step 1

Enter privileged EXEC mode.

Example:

Device# enable

Step 2

Collect AP crash information.

Example:

Device# ap name ap-name crash-file get-crash-data

The crash file is uploaded automatically after the AP reloads to the ready state. As a result, this command does not have to be manually executed.

Step 3

Collect the AP core dump file for slot 0 or slot 1.

Example:

Device# ap name ap-name crash-file get-radio-core-dump slot {0 | 1}

Step 4

Upload the AP crash coredump file to the given TFTP location.

Example:

Device# ap name ap-name core-dump tftp-ip crash-file uncompress

Step 5

Display your AP crash file and the radio crash file.

Step 6

Display the crash file in bootflash with .crash extension.

Example:

Device# dir bootflash

The AP crash files and core dumps are collected and available in specified locations for troubleshooting.

LED states for access points

A LED state for access points is a configuration that

  • allows the identification of specific access points in a LAN network,

  • can be configured globally or for individual APs, and

  • prioritizes global configurations over individual AP settings.


Note

When disabling the LED on an access point, note that the LED state that is controlled by the AP-Join profile.

To maintain the LED in a disabled state, it is recommended to create a separate AP-Join profile and Site Tag specifically for APs with the LED disabled.


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.

Access point tag persistency

Access point tag persistency allows mapped tags to be saved on the APs.

  • Enabled globally on the controller from Cisco IOS XE Bengaluru 17.6.1 onwards.

  • Eliminates the need to write tag configurations individually on each AP.

Supporting reference information

Access point tag persistency is disabled by default. When APs join a controller with tag persistency enabled, the mapped tags are saved on the APs.

Configure access point tag persistency (GUI)

The purpose of this task is to enable tag persistency on access points, allowing them to retain their tag mapping information without requiring individual configuration after reconnection.

Configure access point tag persistency (CLI)

The purpose of this task is to configure access point tag persistency to ensure APs maintain their assigned tags when connecting to different controllers, which aids in redundancy scenarios.

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 to which the AP connects. 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 "New Configuration Model" chapter in Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide.


Note

Once enabled, AP tag persistency takes effect during the AP joining process. Therefore, if there are any APs that are already joined to the controller, those APs must rejoin the controller.

Procedure

Step 1

Enter global configuration mode.

Example:

Device# configure terminal

Step 2

Configure AP tag persistency

Example:

Device(config)# ap tag persistency enable

Step 3

Exit configuration mode and return to privileged EXEC mode.

Example:

Device(config)# end

After completing these steps, the AP tag persistency feature will be enabled on the controller, ensuring APs keep their tag assignments when moving to different controllers.

Verify access point tag persistency

To verify AP tag persistency in the primary controller, use this 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 this 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.

Access point 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.

Feature history for access point power save

Table 1. Feature History

Release

Feature Information

The following features are supported:

  • Radio spatial streams

  • Flexible PoE profiles

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 Cupertino 17.8.1

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

For more information about the APs that support the AP Power Save feature, see https://www.cisco.com/c/en/us/td/docs/wireless/access_point/feature-matrix/ap-feature-matrix.html.

Access point power policies

Access point power policies are a set of policies that

  • define power budget utilization for an AP,

  • allow management of different interfaces on an AP, and

  • support different modes for Cisco Catalyst 9124 APs under insufficient power conditions.

Additional reference information

  • Cisco Catalyst 9124 AXI Series APs and Cisco Catalyst 9124D Series APs support up to two radio interfaces (single 5 GHz).

  • Cisco Catalyst 9124 AXE APs support up to three (dual 5 GHz) radio interfaces.

  • Operation modes under 802.3at/PoE+/30W insufficient power conditions include dual or tri-radio modes.

Use case for AP power policy

These are the use cases of an AP power policy:

  • Define a power policy for available power inputs, such as 802.3af, 802.3at, 802.3bt, and DC power.

  • Predetermine AP operations for non-802.3bt power situations with tri-radio or quad-radio APs.

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

A PoE profile is a configuration framework for managing PoE settings that:

  • facilitates negotiation and adaptation of power levels based on AP requirements,

  • comprises fixed and flexible options for interface configuration, and

  • supports policy-based profiles tailored for both normal and power-saving operational modes.

Supporting reference information

  • Fixed PoE Profiles:

    • Fixed PoE Profiles enable APs to negotiate the power required from the switches they are connected to. The power needed can vary between different AP models.

    • If an AP does not receive the power it requests, it operates within the power budget, potentially causing certain interfaces to function under degraded conditions. For instance, radios might operate at 2SS instead of their full 4SS capability.

    • These profiles are used when APs are in normal operation mode (nonpower-save mode). During power-save mode, the configured PoE power policies are applied instead.

  • PoE Power Policy:

    • PoE Power Policies allow for the configuration of interfaces to specific speeds or settings according to a schedule.

    • These policies can push a defined profile to APs based on timing or calendar settings, such as turning off all but the 2.4-GHz radio and the multigigabit Ethernet at 100 MB at specific times, for example, from 7 p.m. to 7 a.m. on a group of APs located on a second floor.

  • Flexible PoE Profiles:

    • Flexible PoE Profiles allow you to configure different interfaces with specific parameter values and states, instead of fixed profile rules.

    • In cases where an AP does not obtain the necessary power, it operates under the power budget, following the guidelines of the flexible PoE profile.

Additional Reference Information

  • Cisco IOS XE 17.13.1 introduces a new interface, PoE-out, for Cisco Catalyst 9124 Series APs. This interface, alongside USB, Ethernet, and LAN, enables PoE-out only if the RLAN port is activated.

  • Operational parameters for each AP interface may be modified based on the hardware specifications, as detailed in the accompanying tables.

Wakeup threshold for access point power save mode

A wakeup threshold is a power management feature in access points that

  • allows the definition of a client threshold within the AP power profile configuration,

  • determines when the AP applies the calendar-associated power profile to wake up from power save mode, and

  • manages the conditions to either shut down the interface or lower interface speed to conserve power.

When the AP applies the power profile associated with the calendar for an active calendar, and the number of connected clients reaches the wakeup threshold, it triggers the AP to exit power save mode. Conversely, when the number of connected clients is less than the wakeup threshold, the AP will either shut down the interface or reduce the interface speed to save power.

This feature is useful in maintaining optimal energy efficiency by adjusting the AP's operation based on connected client demand.

  • If there are enough clients connected to reach the defined threshold, the AP becomes active to ensure adequate performance.

  • If client connections drop below the threshold, the AP powers down or reduces speed to conserve energy.

Access point power save scenarios

A smart energy AP scenario is a situation where

  • APs implement energy-saving modes

  • adjust power modes to optimize energy efficiency, and

  • apply PoE power policies based on calendar profiles.

The power Save feature helps APs enter a power-save mode or low-power mode by associating a calendar with the corresponding power profile. This feature is aimed at conserving energy during periods with lower activity, such as after hours.

Examples

  • AP in eco mode behavior on 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 connect to the AP. From 7:00 p.m. to 12:00 midnight., 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 1. AP in Eco Mode Behavior: Working Days
    This image shows the Access Point in Eco Mode Behaviour in the working day scenario.

  • AP in eco mode behavior on nonworking days: On nonworking days, the AP enters 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 there are no clients connected to the AP, and the AP is asleep.

    Figure 2. AP in Eco Mode Behavior: Nonworking Days
    This image shows the Access Point in Eco Mode Behavior in the nonworking day scenario

  • AP behavior when clients connect: When clients are connected to the AP, the AP switches to the normal mode based on client connections. 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 dissociate 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.

    This image shows the Access Point in Eco Mode Behavior with Clients

Configure power policy profile (GUI)

Use the GUI to configure a power policy profile, enabling you to manage power settings for network components effectively.

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 your power profile. Ensure the name contains only ASCII characters, up to 128 characters, without leading or trailing spaces.

Step 4

Click Add to add rules for the power profile.

Step 5

Enter a unique sequence number in the Sequence number field to designate the priority for power disablement of the component. A sequence number of 0 indicates the component is 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 have previously chosen.

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.

After configuration, you can effectively manage power for network components.

Configure a power policy profile (CLI)

et up a power policy profile to manage AP energy by configuring Ethernet and USB components through the CLI.

Before you begin

Make sure you activate at least one radio interface before configuring a power policy profile.

Procedure

Step 1

Enter global configuration mode.

Example:

Device# configure terminal

Step 2

Configure the power policy profile.

Example:

Device(config)# wireless profile power power-profile-name

Step 3

Configure the power policy for Ethernet.

Example:

Device(config-wireless-power-profile)# 10 ethernet gigabitethernet1 speed 1000mbps

sequence-number : You can derate the AP based on the sequence number you enter. The same combination of interface identifiers and parameter values does not appear in another sequence number. The same interface with the same parameter can appear multiple times with different parameter values, however, the parameter value that yields the lowest power consumption is the one that gets selected, irrespective of the sequence number if there is active calendar.

Note

 

  • The Ethernet interface is used to join the controller. The uplink interface is not disabled even if it is defined in the power policy.

  • Ethernet speed configuration is not operational in Cisco IOS XE 17.8.1 and later releases.

Step 4

Configure the power policy for USB.

Access point real-time statistics

An access point real-time statistic is a tool that

  • allows tracking of CPU utilization and memory usage of an AP,

  • monitors the health of an AP, and

  • generates real-time statistics from an AP.

Starting from Cisco IOS XE 17.5.1, you can monitor both CPU utilization and memory usage to assess the health of an AP through generated real-time statistics.

Feature history for real time access point statistics

Table 9. Feature history

Release

Feature

Feature information

Cisco IOS XE 17.7.1

Real time access point statistics

The system implements this feature with AP threshold values between 0 and 50.

  • SNMP Traps: SNMP traps are notifications sent out when thresholds are crossed for specific statistics like CPU and memory usage in both the APs and the controller.

  • Sampling Period and Statistics Interval: These parameters can be configured using SNMP, YANG, and CLI to manage how frequently statistics are sampled and reported.

Supporting reference information

SNMP traps are sent out when the threshold is crossed. The sampling period and statistics interval can be configured using SNMP, YANG, and CLI.

From Cisco IOS XE 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.

Restrictions for AP radio monitoring statistics

You cannot reset the radio firmware from the controller. The controller will shut and then restart the radio if the Rx or Tx count does not increase for a radio slot within a specified period.

Configure access point real time statistics (GUI)

This task helps you configure real-time statistics for access points using a graphical user interface, allowing you to effectively monitor and manage AP behavior.

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 and 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 range is between 0 and 3600 seconds.

  • In the Trap Retransmission Time field, enter the time between retransmissions of the alarm. The range is between 0 and 65,535 seconds.

  • To define how often data should be collected from the AP, enter a value in the Sampling Interval field. The 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 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.

The AP monitors real-time statistics and triggers alarms based on defined thresholds to aid you in efficiently managing AP resources.

Example:

Device(config-ap-profile)# statistics ap-system-monitoring alarm-hold-time 400

The values range from 0 to 3600 seconds.

Step 7

Define the retransmission interval for the trap alarms.

Example:

Device(config-ap-profile)# statistics ap-system-monitoring alarm-retransmit-time 100

Set the interval, with values from 0 to 65535 seconds, for retransmitting trap alarms when conditions persist.

Step 8

Define the CPU usage threshold for the AP to trigger alarms.

Example:

Device(config-ap-profile)# statistics ap-system-monitoring cpu-threshold 90

Note

 

From Cisco IOS XE 17.7.1 release onwards, the threshold value for triggering alarms is from 0 to 100%.

Step 9
