Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide, Cisco IOS XE 17.14.x

AP console configurations

An AP console configuration is a controller-managed setting that

allows administrators to enable or disable console access for APs from the controller
operates independently from the FIPS or high-security (CC) mode in certain software versions, and
can be configured through both the controller GUI and CLI.

Enable the console independently of FIPS mode by configuring the AP join profile. If you enable CC mode, console and SSH access are disabled. Any AP console settings configured in the AP profile are overridden by CC mode.

AP audit configuration

An AP audit configuration is a wireless network management feature that

detects and reports synchronization issues between the controller and an AP
provides both real-time and periodic comparison of configuration and operational states, and
supports automated error reporting using syslog for discrepancies.

In Cisco IOS XE Amsterdam, Release 17.3.1, two methods are implemented to support AP audit configuration.

Config Checker
Config Audit

Config Checker audits the application of wireless policies during the AP join phase. Any discrepancies detected at this stage are reported to the controller. This function is built-in and cannot be disabled. When you configure AP attributes such as name, IP address, controller information, tag, mode, radio mode, and radio admin state, the AP parses the CAPWAP payload configuration from the controller. It then reports any detected errors to the controller using the proper code. If a discrepancy is detected, the controller flags errors using the syslog.

Config Audit periodically compares operational states between an AP and the controller after the AP joins and while it remains connected. When discrepancies are found, Config Audit reports them immediately on the controller. You can view a consolidated report at any time. By default, this functionality is disabled. You can configure the periodic auditing interval.

Use the ap audit-report command to enable and configure audit report parameters. When you trigger the audit, the AP sends its configurations to the controller. The controller compares these configurations with the current settings. If there is a mismatch, the controller reports the error using syslog.

Feature history

Table 2. Feature history for AP audit configuration
Feature Name	Release Information	Feature Description
AP audit configuration	Cisco IOS XE 17.3.1	This feature enables real-time and periodic detection, reporting, and automated syslog alerting of synchronization discrepancies between the wireless controller and APs.

Restrictions for AP audit configuration

Config checker alerts are available only through the syslog.
IOS AP is not supported.
Audit reports do not synchronize from the active controller to the standby controller. After SSO, you cannot access audit reports until the next reporting interval for already connected APs.
Audit reports are not available when an AP operates in standalone mode.
This feature is supported only on APs in FlexConnect mode.

Configure AP audit parameters (CLI)

Enable and customize AP audit reporting to monitor and compare AP operational states against controller expectations.

The AP sends state view details to the controller, and the controller compares it with what it perceives as the AP state. This feature is disabled by default.

Procedure

Step 1

Enter the global configuration mode.

Example:

Device# configure terminal

Step 2

Enable audit reporting.

Example:

Device(config)# ap audit-report enable

Step 3

Configure the AP audit reporting interval.

Example:

Device(config)# ap audit-report interval interval 1300

selection : configures the 802.11b antenna to use either the internal or external option.

Note

For APs that support self-identifying antennas (SIA), the gain depends on the antenna and not the AP model. The AP automatically learns the gain, so no controller configuration is necessary.
For APs that do not support SIA, the AP sends the antenna gain in the configuration payload. The default antenna gain depends on the AP model.
Cisco Catalyst 9120E and 9130E APs support self-identifying antennas (SIA). Cisco Catalyst 9115E APs do not support SIA antennas. Although Cisco Catalyst 9115E APs work with SIA antennas, they do not automatically detect SIA antennas or apply the correct external gain.

Note

For APs supporting self-identifying antennas (SIA), the gain depends on the antenna, not on the AP model. The AP learns the gain, so controller configuration is not required.
For APs that do not support SIA, the AP sends the antenna gain in the configuration payload. The default antenna gain depends on the AP model.
Cisco Catalyst 9120E and 9130E APs support self-identifying antennas (SIA). Cisco Catalyst 9115E APs do not support SIA antennas. Although Cisco Catalyst 9115E APs work with SIA antennas, these APs do not automatically detect SIA antennas or add the correct external gain.

Step 3

Configure the antenna mode for 802.11a radios for a specific AP hosted on slot 1.

Example:

Configure 6-GHz radio support for the specified slot number

Enable and configure 6-GHz wireless radios on a Cisco AP to operate optimally within regulatory requirements.

Before you begin

Set the static channel before you change the channel width. As there are no external antenna APs, antennas must be captive (always internal) for 6-GHz, in accordance with regulatory requirements.

Procedure

Step 1

Enter the privileged EXEC mode.

Example:

Device# enable

Step 2

Configure the antenna port for 802.11 6-Ghz radios for a specific AP.

XOR radio support

Dual-band radios in Cisco AP models

A dual-band radio is a device category that

offers connectivity on more than one frequency band (such as 2.4 GHz and 5 GHz)
provides flexibility in network configuration, and
is used in multiple Cisco AP models like the 2800, 3800, 4800, and 9120 series.

Feature history table

Table 3. Feature history table for dual-band radios in Cisco AP models
Feature name	Release information	Feature description
Dual-band (XOR) radio support	Cisco IOS XE 16.10.1	The Dual-band (XOR) radio support offers the ability to serve 2.4 GHz or 5 GHz bands or passively monitor both the bands on the same AP. These APs can be configured to serve clients in 2.4 GHz and 5 GHz bands, or serially scan both 2.4 GHz and 5 GHz bands on the flexible radio while the main 5 GHz radio serves clients.

Key features of dual-band radios in Cisco APs

The XOR radio support can be steered manually or automatically.

Manual steering of a band on a radio: The band on the XOR radio can only be changed manually.
Automatic client and band steering on radios: This is managed by the Flexible Radio Assignment (FRA) feature that monitors and changes the band configurations as per site requirements.

Client steering

When a radio moves between bands (from 2.4 GHz to 5 GHz and vice versa), clients need to be steered to get an optimal distribution across radios. When an AP has two radios in the 5 GHz band, client steering algorithms contained in the FRA algorithms are used to steer a client between the same band co-resident radios

Cisco APs and dual-band radios

Cisco 2800, 3800, 4800, and 9120 series AP models are equipped with dual-band (XOR) radios. These models have

radios that operate on either 2.4 GHz or 5 GHz bands, or
the ability to passively monitor both the bands on the same AP.

These APs can be configured to serve clients in 2.4 GHz and 5 GHz bands, or serially scan both 2.4 GHz and 5 GHz bands on the flexible radio while the main 5 GHz radio serves clients.

Cisco AP models up to the Cisco 9120 APs are designed to support dual 5 GHz band operations with the i model supporting a dedicated Macro or Micro architecture and the e and p models supporting Macro or Macro. The Cisco 9130AXI APs support dual 5 GHz operations as Macro or Micro cell.The CW9166I supports Macro or Macro cell.

Cisco Catalyst Wireless 9166 AP (CW9166) has XOR function for a dual 5 GHz 4x4 or 5 GHz 4x4 and 6 GHz 4x4 radios. These radios can also be configured as client serving, monitor or as a sniffer interface like the earlier XOR radios.

Note

For all countries that do not support 6 GHz spectrum for use of Wi-Fi, when the Cisco Catalyst Wireless 9166I AP operates as dual 5 GHz, the 5 GHz channels will be locked on both the radios even if slot 2 is disabled or set up for monitoring.

Limitations

These are the limitations for XOR radio support:

RF measurement is disabled when a static channel is configured on slot 1. As a result, the dual-band radio slot 0 operates only with 5 GHz radios and not in the monitor mode. When slot 1 radio is disabled, RF measurement will not run, and the dual band radio slot 0 will be only on 2.4 GHz radio.
Only one of the 5 GHz radios can operate in the UNII band (100 to 144), due to an AP limitation to maintain the power budget within the regulatory limit.

Configure default XOR radio support (CLI)

Complete this task to configure the basic settings for XOR radio support.

Before you begin

Note

The default radio points to the XOR radio hosted on slot 0.

Procedure

Step 1	Enable the priviledged EXEC mode. Example: `Device> enable`
Step 2	Configure the 802.11 dual-band external antenna gain on the AP. Example: `Device# ap name ap-name dot11 dual-band antenna ext-ant-gain antenna_gain_value` Enter external antenna gain value in multiple of .5 dBi units (that is, an integer value 4 means 4 x 0.5 = 2 dBi of gain).
Step 3	Shut down the default dual-band radio. Example: `Device# ap name ap-name dot11 dual-band shutdown` Use the no form of the command to enable the radio.
Step 4	Switch to the client-serving mode of the AP. Example: `Device# ap name ap-name dot11 dual-band role manual client-serving`
Step 5	Switch to the 2.4 GHz radio band. Example: `Device# ap name ap-name dot11 dual-band band 24ghz`

The basic configuration of the XOR radio is completed.

Example

Device> enable
Device# ap name ap-name  dot11 dual-band antenna ext-ant-gain 2
Device# ap name ap-name  dot11 dual-band shutdown
Device# Device# ap name ap-name  dot11 dual-band role manual client-serving
Device# Device# ap name ap-name  dot11 dual-band band 24ghz

What to do next

Continue with the configuration steps listed in the "Configure advanced settings" to complete the configuration.

Configure advanced settings (CLI)

Complete this task to configure the advanced settings for XOR radio support, such as, transmit power, channel, channel width, CleanAir settings and so on.

Procedure

Step 1

Configure the transmit power for the radio on the AP.

Example:

Device# ap name ap-name  dot11 dual-band txpower {transmit_power_level | auto}

Note

When an FRA-capable radio (slot 0 on 9120 AP[for instance]) is set to Auto, you cannot configure static channel and Txpower on this radio.

If you want to configure static channel and Txpower on this radio, you will need to change the radio role to Manual Client-Serving mode.

This note is not applicable for Cisco Catalyst Wireless 9166 AP (CW9166).

Step 2

Configure the channel number for the dual band.

Example:

Device# ap name ap-name  dot11 dual-band channel 40

The range of the channel-number is from 1 to 173.

Step 3

(Optional) Enable the auto channel assignment for the dual-band.

Example:

Device# ap name ap-name  dot11 dual-band channel auto

Step 4

Example:

Device# ap name ap-name  dot11 dual-band channel width {20 MHz | 40 MHz | 80 MHz | 160 MHz}

Step 5

Enable the Cisco CleanAir management on the dual-band radio.

Example:

Device# ap name ap-name  dot11 dual-band cleanair

Step 6

Configure a band for the Cisco CleanAir feature.

Example:

Device# ap name ap-name [no] dot11 dual-band cleanair band 5 GHz

Selects a band for the Cisco CleanAir feature.

Use the no form of this command to disable the Cisco CleanAir feature.

Step 7

Configure the 802.11n dual-band antenna and antenna ports selection for a specific AP.

Device# ap name ap-name  dot11 dual-band dot11n antenna {A | B | C | D}

Here, A, B, C, and D are the antenna ports.

The configuration of the additional features for dual-band (XOR) radios are completed.

Example

Device# ap name ap-name  dot11 dual-band txpower auto
Device# ap name ap-name  dot11 dual-band channel 40
Device# ap name ap-name  dot11 dual-band channel width 40 MHz
Device# ap name ap-name  dot11 dual-band cleanair
Device# ap name ap-name [no] dot11 dual-band cleanair band 5 GHz
Device# ap name ap-name  dot11 dual-band dot11n antenna A

Configure XOR radio support for the specified slot number (CLI)

Complete this task to configure XOR radio for a specified slot number.

Procedure

Step 1

Enable the priviledged EXEC mode.

Example:

Device> enable

Step 2

Configure dual-band antenna for the XOR radio hosted on slot 0 for a specific AP.

Example:

Device# ap name ap-name dot11 dual-band slot 0 antenna ext-ant-gain external_antenna_gain_value

Here, external_antenna_gain_value is the external antenna gain value in multiples of .5 dBi unit. The range is from 0 to 40.

Note

For APs supporting self-identifying antennas (SIA), the gain depends on the antenna, and not on the AP model. The gain is learned by the AP and there is no need for controller configuration.
For APs that do not support SIA, the APs send the antenna gain in the configuration payload, where the default antenna gain depends on the AP model.

Step 3

Configure the current band for XOR radio hosted on slot 0 for a specific AP.

Example:

Device# ap name ap-name dot11 dual-band slot 0 band {24ghz | 5ghz}

Example:

Device# ap name ap-name dot11 dual-band slot 0 channel {channel-number | auto | width [160 | 20 | 40 | 80]}

The range of the channel_number is from 1 to 165.

Step 5

Enable the Cisco CleanAir feature for dual-band radios hosted on slot 0 for a specific AP.

Example:

Device# ap name ap-name dot11 dual-band slot 0 cleanair band {24Ghz | 5ghz}

Step 6

Configure 802.11n dual-band parameters hosted on slot 0 for a specific AP.

Example:

Device# ap name ap-name dot11 dual-band slot 0 dot11n antenna {A | B | C | D}

Here are the antenna configurations.

A : Enables antenna port A.

B : Enables antenna port B.

C : Enables antenna port C.

D : Enables antenna port D.

Step 7

Configure dual-band role for the XOR radio hosted on slot 0 for a specific AP.

Example:

Device# ap name ap-name dot11 dual-band slot 0 role {auto | manual [client-serving | monitor]}

Here are the dual-band roles.

auto : refers to the automatic radio role selection.
manual : refers to the manual radio role selection.

Note

When Flexible Radio Assignment (FRA) is disabled, XOR radios whose roles were changed by Radio Resource Management (RRM) might not automatically revert to their default radio role. To restore an individual AP to the default client-serving role, use the these commands:

Device# ap name ap-name dot11 dual-band slot 0 shutdown

Device# ap name ap-name dot11 dual-band slot 0 role manual client-serving

Device# ap name ap-name dot11 dual-band slot 0 band 24ghz

Device# ap name ap-name no dot11 dual-band slot 0 shutdown

Step 8

Disable dual-band radio hosted on slot 0 for a specific AP.

Example:

Device# ap name ap-name [no] dot11 dual-band slot 0 shutdown

Use the no form of this command to enable the dual-band radio.

Step 9

Configure dual-band transmit power for XOR radio hosted on slot 0 for a specific AP.

Example:

Device# ap name ap-name dot11 dual-band slot 0 txpower {tx-power-level | auto}

Here,

tx_power_level : is the transmit power level in dBm. The range is from 1 to 8.
auto : enables auto-RF.

The XOR radio for the specified slot number is configured.

Example

Device> enable
                Device# ap name AP-SIDD-A06 dot11 dual-band slot 0 antenna ext-ant-gain 2
                Device# ap name AP-SIDD-A06 dot11 dual-band slot 0 band 24ghz

Cisco flexible antenna port

A Cisco flexible antenna port is an antenna configuration feature that

enables APs to assign antenna ports as either single-band or dual-band
optimizes wireless coverage and performance through flexible radio assignments, and
supports both 2.4 GHz and 5 GHz wireless bands to accommodate various deployment scenarios.

Multiple antennas on the transmitters and receivers improve AP performance and reliability for your wireless deployment. Multiple antennas improve reception by selecting stronger signals or combining individual signals at the receiver. These mechanisms help APs deliver reliable wireless coverage. You can configure AP antenna ports as dual-band or single-band antennas to optimize radio coverage for your environment.

In dual-band antenna mode, APs operate in both the 2.4 GHz and 5 GHz bands using all four antennas A, B, C, and D. An example of a dual-band antenna mode AP is the Cisco Industrial Wireless 3702 AP.
In single-band antenna mode, antennas A and B operate in the 2.4 GHz band, while antennas C and D operate in the 5 GHz band. An example of a single-band antenna mode AP is the Cisco Catalyst Industrial Wireless 6300 AP.

CAPWAP LAG support

A CAPWAP LAG support feature is a controller-access point connectivity mechanism that

enables link aggregation of controller ports.
allows automatic failover of traffic if a port fails, and
simplifies controller configuration by removing the requirement to configure primary and secondary ports for each interface.

Link aggregation ensures that traffic is redirected automatically to a functioning port if one controler port fails. With at least one controller port operating, network connectivity is maintained, APs stay connected and wireless clients remain operational.

CAPWAP (Control and Provisioning of Wireless Access Points) is a protocol that manages communication between wireless LAN controllers and access points.

Link Aggregation refers to using multiple network connections in parallel to increase throughput and provide redundancy.

Supported models

The CAPWAP LAG support feature applies to APs with multiple Ethernet ports for CAPWAP.

11AC APs with dual Ethernet ports require CAPWAP AP LAG support for their data channels.
By default, the second port on Cisco Aironet 1850, 2800, and 3800 Series APs is used for link aggregation. If you disable LAG, you can use the LAG port as an RLAN port.

These APs use LAG port as an RLAN (Remote LAN) port:

Cisco Aironet 1852E Access Point
Cisco Aironet 1852I Access Point
Cisco Aironet 2802E Access Point
Cisco Aironet 2802I Access Point
Cisco Aironet 3802E Access Point
Cisco Aironet 3802I Access Point
Cisco Aironet 3802P Access Point
Cisco Catalyst 9136I Access Point

Restrictions for CAPWAP LAG support

Ensure these requirements are met when using CAPWAP LAG support.

APs must be specifically enabled for CAPWAP AP LAG support.
CAPWAP data does not support IPv6.
Do not enable Datagram Transport Layer Security (DTLS) when you enable LAG.
CAPWAP LAG does not work with APs behind Network Address Translation (NAT) or Port Address Translation (PAT).

Activate tracking for deactivated infrastructure devices (GUI)

Use this procedure to initiate tracking for an inactive infrastructure device that has been deactivated. After the switch or AP becomes active, CUCM tracks its status and provides a list of endpoints that associate to the switch or AP.

Note

The controller synchronization process only adds new APs to the list and does not remove APs if they are not found.

To remove APs from the infrastructure list, mark them as inactive. After they are marked as inactive, navigate to the inactive page and delete the APs.

Because APs are stored independently in the database, controllers and APs are not directly associated. If you delete a controller, CUCM does not track AP or controller associations. APs learned from the controller stay in the system.

Before you begin

Configure Location Awareness. For more information, refer to the "Location Awareness" chapter in the System Configuration Guide for Cisco Unified Communications Manager.

Procedure

Step 1	In Cisco Unified CM Administration, choose Advanced Features > Device Location Tracking Services > Switches and Access Points.
Step 2	From Related Links, choose Inactive Switches and Access Points and click Go. The Find and List Inactive Switches and Access Points window displays the infrastructure devices that are not being tracked.
Step 3	Select the switch or AP for which you want to initiate tracking.
Step 4	Click Reactivate Selected.

CAPWAP message aggregation

Control and provisioning of wireless APs message aggregation

A CAPWAP message aggregation is a wireless communication optimization feature that

combines multiple CAPWAP control messages of the same type into a single transmission
temporarily stores messages in the controller when APs are busy processing packets, and
limits the aggregated message size to the configured Maximum Transmission Unit (MTU) to maximize transmission efficiency.

AP audit configuration

An AP audit configuration is a wireless network management feature that

detects and reports synchronization issues between the controller and an AP
provides both real-time and periodic comparison of configuration and operational states, and
supports automated error reporting using syslog for discrepancies.

In Cisco IOS XE Amsterdam, Release 17.3.1, two methods are implemented to support AP audit configuration.

Config Checker
Config Audit

Config Checker audits the application of wireless policies during the AP join phase. Any discrepancies detected at this stage are reported to the controller. This function is built-in and cannot be disabled. When you configure AP attributes such as name, IP address, controller information, tag, mode, radio mode, and radio admin state, the AP parses the CAPWAP payload configuration from the controller. It then reports any detected errors to the controller using the proper code. If a discrepancy is detected, the controller flags errors using the syslog.

Config Audit periodically compares operational states between an AP and the controller after the AP joins and while it remains connected. When discrepancies are found, Config Audit reports them immediately on the controller. You can view a consolidated report at any time. By default, this functionality is disabled. You can configure the periodic auditing interval.

Use the ap audit-report command to enable and configure audit report parameters. When you trigger the audit, the AP sends its configurations to the controller. The controller compares these configurations with the current settings. If there is a mismatch, the controller reports the error using syslog.

Feature history

Table 7. Feature history for AP audit configuration
Feature Name	Release Information	Feature Description
AP audit configuration	Cisco IOS XE 17.3.1	This feature enables real-time and periodic detection, reporting, and automated syslog alerting of synchronization discrepancies between the wireless controller and APs.

Restrictions for AP audit configuration

Config checker alerts are available only through the syslog.
IOS AP is not supported.
Audit reports do not synchronize from the active controller to the standby controller. After SSO, you cannot access audit reports until the next reporting interval for already connected APs.
Audit reports are not available when an AP operates in standalone mode.
This feature is supported only on APs in FlexConnect mode.

Configure AP audit parameters (CLI)

Enable and customize AP audit reporting to monitor and compare AP operational states against controller expectations.

The AP sends state view details to the controller, and the controller compares it with what it perceives as the AP state. This feature is disabled by default.

Procedure

Step 1

Enter the global configuration mode.

Example:

Device# configure terminal

Step 2

Enable audit reporting.

Example:

Device(config)# ap audit-report enable

Step 3

Configure the AP audit reporting interval.

Example:

For APs supporting self-identifying antennas (SIA), the gain depends on the antenna, not on the AP model. The AP learns the gain, so controller configuration is not required.
For APs that do not support SIA, the AP sends the antenna gain in the configuration payload. The default antenna gain depends on the AP model.
Cisco Catalyst 9120E and 9130E APs support self-identifying antennas (SIA). Cisco Catalyst 9115E APs do not support SIA antennas. Although Cisco Catalyst 9115E APs work with SIA antennas, these APs do not automatically detect SIA antennas or add the correct external gain.

Step 3

Configure the antenna mode for 802.11a radios for a specific AP hosted on slot 1.

Configure 6-GHz radio support for the specified slot number

Enable and configure 6-GHz wireless radios on a Cisco AP to operate optimally within regulatory requirements.

Before you begin

Set the static channel before you change the channel width. As there are no external antenna APs, antennas must be captive (always internal) for 6-GHz, in accordance with regulatory requirements.

Procedure

Step 1

Enter the privileged EXEC mode.

Example:

Device# enable

Step 2

Configure the antenna port for 802.11 6-Ghz radios for a specific AP.

Dual-band radios in Cisco AP models

A dual-band radio is a device category that

offers connectivity on more than one frequency band (such as 2.4 GHz and 5 GHz)
provides flexibility in network configuration, and
is used in multiple Cisco AP models like the 2800, 3800, 4800, and 9120 series.

Feature history table

Table 8. Feature history table for dual-band radios in Cisco AP models
Feature name	Release information	Feature description
Dual-band (XOR) radio support	Cisco IOS XE 16.10.1	The Dual-band (XOR) radio support offers the ability to serve 2.4 GHz or 5 GHz bands or passively monitor both the bands on the same AP. These APs can be configured to serve clients in 2.4 GHz and 5 GHz bands, or serially scan both 2.4 GHz and 5 GHz bands on the flexible radio while the main 5 GHz radio serves clients.

Key features of dual-band radios in Cisco APs

The XOR radio support can be steered manually or automatically.

Manual steering of a band on a radio: The band on the XOR radio can only be changed manually.
Automatic client and band steering on radios: This is managed by the Flexible Radio Assignment (FRA) feature that monitors and changes the band configurations as per site requirements.

Client steering

When a radio moves between bands (from 2.4 GHz to 5 GHz and vice versa), clients need to be steered to get an optimal distribution across radios. When an AP has two radios in the 5 GHz band, client steering algorithms contained in the FRA algorithms are used to steer a client between the same band co-resident radios

Cisco APs and dual-band radios

Cisco 2800, 3800, 4800, and 9120 series AP models are equipped with dual-band (XOR) radios. These models have

radios that operate on either 2.4 GHz or 5 GHz bands, or
the ability to passively monitor both the bands on the same AP.

These APs can be configured to serve clients in 2.4 GHz and 5 GHz bands, or serially scan both 2.4 GHz and 5 GHz bands on the flexible radio while the main 5 GHz radio serves clients.

Cisco AP models up to the Cisco 9120 APs are designed to support dual 5 GHz band operations with the i model supporting a dedicated Macro or Micro architecture and the e and p models supporting Macro or Macro. The Cisco 9130AXI APs support dual 5 GHz operations as Macro or Micro cell.The CW9166I supports Macro or Macro cell.

Cisco Catalyst Wireless 9166 AP (CW9166) has XOR function for a dual 5 GHz 4x4 or 5 GHz 4x4 and 6 GHz 4x4 radios. These radios can also be configured as client serving, monitor or as a sniffer interface like the earlier XOR radios.

Note

For all countries that do not support 6 GHz spectrum for use of Wi-Fi, when the Cisco Catalyst Wireless 9166I AP operates as dual 5 GHz, the 5 GHz channels will be locked on both the radios even if slot 2 is disabled or set up for monitoring.

Limitations

These are the limitations for XOR radio support:

RF measurement is disabled when a static channel is configured on slot 1. As a result, the dual-band radio slot 0 operates only with 5 GHz radios and not in the monitor mode. When slot 1 radio is disabled, RF measurement will not run, and the dual band radio slot 0 will be only on 2.4 GHz radio.
Only one of the 5 GHz radios can operate in the UNII band (100 to 144), due to an AP limitation to maintain the power budget within the regulatory limit.

Configure default XOR radio support (CLI)

Complete this task to configure the basic settings for XOR radio support.

Before you begin

Note

The default radio points to the XOR radio hosted on slot 0.

Procedure

Step 1	Enable the priviledged EXEC mode. Example: `Device> enable`
Step 2	Configure the 802.11 dual-band external antenna gain on the AP. Example: `Device# ap name ap-name dot11 dual-band antenna ext-ant-gain antenna_gain_value` Enter external antenna gain value in multiple of .5 dBi units (that is, an integer value 4 means 4 x 0.5 = 2 dBi of gain).
Step 3	Shut down the default dual-band radio. Example: `Device# ap name ap-name dot11 dual-band shutdown` Use the no form of the command to enable the radio.
Step 4	Switch to the client-serving mode of the AP. Example: `Device# ap name ap-name dot11 dual-band role manual client-serving`
Step 5	Switch to the 2.4 GHz radio band. Example: `Device# ap name ap-name dot11 dual-band band 24ghz`

The basic configuration of the XOR radio is completed.

Example

Device> enable
Device# ap name ap-name  dot11 dual-band antenna ext-ant-gain 2
Device# ap name ap-name  dot11 dual-band shutdown
Device# Device# ap name ap-name  dot11 dual-band role manual client-serving
Device# Device# ap name ap-name  dot11 dual-band band 24ghz

What to do next

Continue with the configuration steps listed in the "Configure advanced settings" to complete the configuration.

Configure advanced settings (CLI)

Complete this task to configure the advanced settings for XOR radio support, such as, transmit power, channel, channel width, CleanAir settings and so on.

Procedure

Step 1

Configure the transmit power for the radio on the AP.

Example:

Device# ap name ap-name  dot11 dual-band txpower {transmit_power_level | auto}

Note

When an FRA-capable radio (slot 0 on 9120 AP[for instance]) is set to Auto, you cannot configure static channel and Txpower on this radio.

If you want to configure static channel and Txpower on this radio, you will need to change the radio role to Manual Client-Serving mode.

This note is not applicable for Cisco Catalyst Wireless 9166 AP (CW9166).

Step 2

Configure the channel number for the dual band.

Example:

Device# ap name ap-name  dot11 dual-band channel 40

The range of the channel-number is from 1 to 173.

Step 3

(Optional) Enable the auto channel assignment for the dual-band.

Example:

Device# ap name ap-name  dot11 dual-band channel auto

Example:

Device# ap name ap-name  dot11 dual-band channel width {20 MHz | 40 MHz | 80 MHz | 160 MHz}

Step 5

Enable the Cisco CleanAir management on the dual-band radio.

Example:

Device# ap name ap-name  dot11 dual-band cleanair

Step 6

Configure a band for the Cisco CleanAir feature.

Example:

Device# ap name ap-name [no] dot11 dual-band cleanair band 5 GHz

Selects a band for the Cisco CleanAir feature.

Use the no form of this command to disable the Cisco CleanAir feature.

Step 7

Configure the 802.11n dual-band antenna and antenna ports selection for a specific AP.

The configuration of the additional features for dual-band (XOR) radios are completed.

Example

Device# ap name ap-name  dot11 dual-band txpower auto
Device# ap name ap-name  dot11 dual-band channel 40
Device# ap name ap-name  dot11 dual-band channel width 40 MHz
Device# ap name ap-name  dot11 dual-band cleanair
Device# ap name ap-name [no] dot11 dual-band cleanair band 5 GHz
Device# ap name ap-name  dot11 dual-band dot11n antenna A

Configure XOR radio support for the specified slot number (CLI)

Complete this task to configure XOR radio for a specified slot number.

Procedure

Step 1

Enable the priviledged EXEC mode.

Example:

Device> enable

Step 2

Configure dual-band antenna for the XOR radio hosted on slot 0 for a specific AP.

Example:

Device# ap name ap-name dot11 dual-band slot 0 antenna ext-ant-gain external_antenna_gain_value

Here, external_antenna_gain_value is the external antenna gain value in multiples of .5 dBi unit. The range is from 0 to 40.

Note

For APs supporting self-identifying antennas (SIA), the gain depends on the antenna, and not on the AP model. The gain is learned by the AP and there is no need for controller configuration.
For APs that do not support SIA, the APs send the antenna gain in the configuration payload, where the default antenna gain depends on the AP model.

Device# ap name ap-name dot11 dual-band slot 0 dot11n antenna {A | B | C | D}

Here are the antenna configurations.

A : Enables antenna port A.

B : Enables antenna port B.

C : Enables antenna port C.

D : Enables antenna port D.

Step 7

Configure dual-band role for the XOR radio hosted on slot 0 for a specific AP.

Example:

Device# ap name ap-name dot11 dual-band slot 0 role {auto | manual [client-serving | monitor]}

Here are the dual-band roles.

auto : refers to the automatic radio role selection.
manual : refers to the manual radio role selection.

Note

When Flexible Radio Assignment (FRA) is disabled, XOR radios whose roles were changed by Radio Resource Management (RRM) might not automatically revert to their default radio role. To restore an individual AP to the default client-serving role, use the these commands:

Device# ap name ap-name dot11 dual-band slot 0 shutdown

Device# ap name ap-name dot11 dual-band slot 0 role manual client-serving

Device# ap name ap-name dot11 dual-band slot 0 band 24ghz

Device# ap name ap-name no dot11 dual-band slot 0 shutdown

Step 8

Disable dual-band radio hosted on slot 0 for a specific AP.

Example:

Device# ap name ap-name [no] dot11 dual-band slot 0 shutdown

Use the no form of this command to enable the dual-band radio.

Step 9

Configure dual-band transmit power for XOR radio hosted on slot 0 for a specific AP.

Example:

Device# ap name ap-name dot11 dual-band slot 0 txpower {tx-power-level | auto}

Here,

tx_power_level : is the transmit power level in dBm. The range is from 1 to 8.
auto : enables auto-RF.

The XOR radio for the specified slot number is configured.

Example

Device> enable
                Device# ap name AP-SIDD-A06 dot11 dual-band slot 0 antenna ext-ant-gain 2
                Device# ap name AP-SIDD-A06 dot11 dual-band slot 0 band 24ghz
                Device# ap name AP-SIDD-A06 dot11 dual-band slot 0 channel 3
                Device# ap name AP-SIDD-A06 dot11 dual-band slot 0 cleanair band 24Ghz
                Device# ap name AP-SIDD-A06 dot11 dual-band slot 0 dot11n antenna A
                Device# ap name AP-SIDD-A06 [no] dot11 dual-band slot 0 shutdown
                Device# ap name AP-SIDD-A06 dot11 dual-band slot 0 txpower 2

Cisco flexible antenna port

A Cisco flexible antenna port is an antenna configuration feature that

enables APs to assign antenna ports as either single-band or dual-band
optimizes wireless coverage and performance through flexible radio assignments, and
supports both 2.4 GHz and 5 GHz wireless bands to accommodate various deployment scenarios.

Multiple antennas on the transmitters and receivers improve AP performance and reliability for your wireless deployment. Multiple antennas improve reception by selecting stronger signals or combining individual signals at the receiver. These mechanisms help APs deliver reliable wireless coverage. You can configure AP antenna ports as dual-band or single-band antennas to optimize radio coverage for your environment.

In dual-band antenna mode, APs operate in both the 2.4 GHz and 5 GHz bands using all four antennas A, B, C, and D. An example of a dual-band antenna mode AP is the Cisco Industrial Wireless 3702 AP.
In single-band antenna mode, antennas A and B operate in the 2.4 GHz band, while antennas C and D operate in the 5 GHz band. An example of a single-band antenna mode AP is the Cisco Catalyst Industrial Wireless 6300 AP.

CAPWAP LAG support

A CAPWAP LAG support feature is a controller-access point connectivity mechanism that

enables link aggregation of controller ports.
allows automatic failover of traffic if a port fails, and
simplifies controller configuration by removing the requirement to configure primary and secondary ports for each interface.

Link aggregation ensures that traffic is redirected automatically to a functioning port if one controler port fails. With at least one controller port operating, network connectivity is maintained, APs stay connected and wireless clients remain operational.

CAPWAP (Control and Provisioning of Wireless Access Points) is a protocol that manages communication between wireless LAN controllers and access points.

Link Aggregation refers to using multiple network connections in parallel to increase throughput and provide redundancy.

Supported models

The CAPWAP LAG support feature applies to APs with multiple Ethernet ports for CAPWAP.

11AC APs with dual Ethernet ports require CAPWAP AP LAG support for their data channels.
By default, the second port on Cisco Aironet 1850, 2800, and 3800 Series APs is used for link aggregation. If you disable LAG, you can use the LAG port as an RLAN port.

These APs use LAG port as an RLAN (Remote LAN) port:

Cisco Aironet 1852E Access Point
Cisco Aironet 1852I Access Point
Cisco Aironet 2802E Access Point
Cisco Aironet 2802I Access Point
Cisco Aironet 3802E Access Point
Cisco Aironet 3802I Access Point
Cisco Aironet 3802P Access Point
Cisco Catalyst 9136I Access Point

Restrictions for CAPWAP LAG support

Ensure these requirements are met when using CAPWAP LAG support.

APs must be specifically enabled for CAPWAP AP LAG support.
CAPWAP data does not support IPv6.
Do not enable Datagram Transport Layer Security (DTLS) when you enable LAG.
CAPWAP LAG does not work with APs behind Network Address Translation (NAT) or Port Address Translation (PAT).
