Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide, Cisco IOS XE Dublin 17.12.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.

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.

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 the radios 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 assively 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.

Wi-Fi 7 APs compatibility

Configure default XOR radio support

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

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

Information About OFDMA Support for 11ax Access Points

The Cisco Catalyst 9100 series access points are the next generation WiFi 802.11ax access point, which is ideal for high-density high-definition applications.

The IEEE 802.11ax protocol aims to improve user experience and network performance in high density deployments for both 2.4 GHz and 5 GHz. The 802.11ax APs supports transmission or reception to more than one client simultaneously using Orthogonal Frequency Division Multiplexing (OFDMA).

The IEEE 802.11ax supports uplink MU-MIMO and also adds OFDMA for multiple users in the uplink and downlink. All the users in IEEE 802.11ax OFDMA have the same time allocations and it ends at the same time. In MU-MIMO and OFDMA, multiple stations (STAs) either simultaneously transmit to a single STA or simultaneously receive from a single STA independent data streams over the same radio frequencies.

Supported Modes on 11ax Access Points

The following AP modes are supported:

Local mode
Flex-connect mode
Bridge mode
Flex+Mesh mode

Note

For 6-GHz radio, the 802.11ax parameters are taken from the multi BSSID profile tagged to the corresponding 6-GHz RF profile of the AP. So, the WLAN dot11ax parameters are overridden by multi BSSID profile parameters in the case of 6-GHz. There are no changes for 2.4 and 5-GHz band WLANs. They continue to use the WLAN parameters for 802.11ax.

Information About Cisco Flexible Antenna Port

The presence of multiple antennas on the transmitters and the receivers of access points (APs), results in better performance and reliability of the APs. Multiple antennas improve reception through the selection of stronger signals or a combination of individual signals, at the receiver. You can configure the antenna ports to be used in the APs as either dual-band antennas or as single-band antennas to optimize radio coverage.

Dual-band antenna mode: APs operate in both the 2.4-GHz and 5-GHz bandwidth with all the four antennas—A, B, C, and D. An example of a dual-band antenna mode AP is the Cisco Industrial Wireless 3702 AP.
Single-band antenna mode: Among the APs, antennas A and B operate in the 2.4-GHz bandwidth, and the antennas C and D operate in the 5-GHz bandwidth. An example of a single-band antenna mode AP is the Cisco Catalyst Industrial Wireless 6300 AP.

Information About CAPWAP LAG Support

Link aggregation (LAG) simplifies controller configuration because you no longer require to configure primary and secondary ports for each interface. If any of the controller ports fail, traffic is automatically migrated to one of the other ports. As long as at least one controller port is functioning, the system continues to operate, access points remain connected to the network, and wireless clients continue to send and receive data.

The CAPWAP LAG support feature is applicable for access points that support multiple ethernet ports for CAPWAP.

The 11AC APs with dual ethernet ports require the CAPWAP AP LAG support for data channel.

Cisco Aironet 1850, 2800, and 3800 Series APs' second Ethernet port is used as a link aggregation port, by default. It is possible to use this LAG port as an RLAN port when LAG is disabled.

The following APs use LAG port as an RLAN port:

1852E
1852I
2802E
2802I
3802E
3802I
3802P
9136I

Restrictions for CAPWAP LAG Support
