For more information, see the chapter Countries and Regulations.

Background Scanning and MAP Fast Ancestor Find Mode

The Background Scanning and MAP Fast Ancestor Find Mode feature updates the child MAPs about their neighbors across all the channels. This feature also helps child MAPs to switch to a neighbor of any channel, and use that neighbor as the next parent for uplink. Background scanning allows MAPs to save time during the scan-and-seek phase while looking for a new parent.

The following command is introduced:

  • map-fast-ancestor-find

For more information, see the chapter Mesh Access Points.

Built-in Captive Portal Improvements

This release introduces support for special characters in the login portal banner title and banner text. The number of characters supported on the banner text has been doubled to 400.

The following command is introduced:

  • exec-character-bits

For more information, see the chapter Web-Based Authentication.

Calendar Profile Enhancement

This release allows you to create a single calendar profile in the controller GUI, spanning across midnight (for example, from 5 p.m. to 7 a.m.), instead of two separate calendar profiles.

Client Debug Bundle

This feature helps to collate the radioactive trace debug logs, packet captures in a control plane, AP logs, and the output of show commands related to clients, which are useful in troubleshooting wireless client issues. The log is collected in a tar file through a single debug command.

The following commands are introduced:

  • debug wireless bundle client abort

  • debug wireless bundle client mac

  • debug wireless bundle client start

  • debug wireless bundle client stop-all collect

For more information, see the chapter Conditional Debug, Radioactive Tracing, and Packet Tracing.

Convert Redundant 2.4-GHz Radios to Monitor Mode

From this release, you can select the redundant dual-band radios in a network to operate in monitor only mode.

For more information, see the chapter Cisco Flexible Radio Assignment.

Enhancement in Client Steering During Rolling AP Upgrade

This release introduces the option to not deauthenticate clients connected to the APs that are selected for the upgrade. Use the no ap upgrade staggered client-deauth command to stop deauthenticating clients before the AP performs an upgrade.

By default, the AP deauthenticates all clients before performing an upgrade.

For more information, see the chapter N+1 Hitless Rolling AP Upgrade.

Flex OTT and Roaming Latency Validation over BGP EVPN

This release supports Over The Top (OTT) Ethernet Virtual Private Network (EVPN) solution.

For more information on the EVPN solution, see the BGP EVPN VXLAN Configuration Guide.

GNSS Support

AP tracks GPS information for devices deployed in the outdoor environment and sends the GNSS information to the wireless controller.

The following command is introduced on the AP: show gnss info.

The following commands display the GPS location of the AP:

  • show ap geolocation summary

  • show ap name geolocation detail

For more information, see Cisco Catalyst IW9167E Heavy Duty Access Point Configuration Guide.

iCAP Spectrum Analysis Enable and Update

The spectral capture update rate (using iCAP on Cisco DNA Centre) for the WiFi6E APs, such as 9136, 9166, 9164, and 9162, are improved by about 70 percent. Rogue client detection is impacted slightly while performing spectral capture. However, rogue AP detection is not affected and impacts only the APs performing spectral capture. When Fastlocate, Cisco Hyperlocation, or Rogue Containment features are enabled, spectral capture updates won't cause an impact.

When you perform a full packet data capture for a Wifi6E client using Cisco DNA Center, the broadcast frames, such as FILS and UPBR, do not appear in the packet data capture. The only broadcast frames included are management frames beacon.

Jumbo Frame Support for RADIUS Packets

This release supports higher RADIUS packet fragmentation. The fragmentation size is increased to 9000 bytes.

For more information, see the chapter Multiple Authentications for a Client.

Location-Capable Attribute in the Access-Request Messages

This release supports Location-Capable attribute from RFC 5580, which provides details of the available location profiles' configuration on the device.

  • AIRESPACE-WIRELESS-CAPABILITY

  • AIRESPACE-WIRELESS-MIB

  • CISCO-LWAPP-AP-MIB

  • CISCO-LWAPP-TC-MIB

Strong Crypto Algorithms

We strongly recommend stronger cryptographic algorithms instead of weak cryptographic algorithms, such as RSA keys of less than 2048 bits, MD5 for authentication, DES, and 3DES for encryption. Soon, such weak algorithms will no longer be allowed by default. An explicit configuration is required to continue using such weak algorithms.

For SNMP v3 users with weak cryptographic properties, the SNMP operations to the device will fail, resulting in loss of management access to device through SNMP. Similarly, if the RSA key pair is not updated to be at least 2048 bits for SSH, the SSH server will be disabled, resulting in loss of remote access to the device through SSH.

For more information on how to migrate to stronger cryptographic algorithms for SNMP, see the Field Notice Number: FN72509.

For more information on how to migrate to stronger cryptographic algorithms for SSH, see Field Notice Number: FN72511.

Product Analytics

This feature allows for the collection of non-personal usage device systems information for Cisco products, which helps in continuous product improvements. This feature is supported on the Cisco Catalyst 9800 Series Wireless Controllers (9800-80, 9800-40, 9800-L, and 9800-CL). You can use the the pae command to enable or disable this feature.

The following commands are introduced as part of this feature:

  • pae

  • show product-analytics kpi

  • show product-analytics report

  • show product-analytics stats


Note


Turning off Smart Licensing Device Systems Information does not impact other Systems Information collection including from Cisco Catalyst Center or vManage.


Important: Cisco is constantly striving to advance our products and services. Knowing how you use our products is key to accomplishing this goal. To that end, Cisco will collect device and licensing Systems Information through Cisco Smart Software Manager (CSSM) for product and customer experience improvement, analytics, and adoption. Cisco processes your data in accordance with the General Terms and Conditions, the Cisco Privacy Statement and any other applicable agreement with Cisco. To modify your organization’s preferences for device and licensing systems information, use the pae command. For more information, see Cisco Catalyst 9800 Series Wireless Controller Command Reference.

For additional information on this feature, see Wireless Product Analytics FAQ.

Behavior Changes

  • When nonrealm clients join realm-enabled SSIDs, accounting requests are sent to the AAA server that is mapped to the accounting method list configured under the policy profile after clients move to the RUN state.

  • CAPWAP packets that are sent towards APs are tagged with a device tag.

  • From this release, Online subscription with Encryption (OSEN) can be enabled with WPA2.

  • From Cisco IOS XE Dublin 17.11.1, for 6-GHz bandwidth, the DBS Minimum Channel Width and DBS Maximum Channel Width fields are moved from Configuration > Radio Configurations > RRM > 6 Ghz Band > General to Configuration > Tags & Profiles > RF Profile > RRM > DCA > Channel width > DBS channel width.

  • If you have configured CISCO_IDEVID_SUDI trustpoint in your configuration, you will need to replace it with CISCO_IDEVID_CMCA3_SUDI to avoid client connection and AP join issues. The reason for this change being the CISCO_IDEVID_SUDI changed from SW-SUDI certificate in previous releases to HW-SUDI certificate. The processing of HW-SUDI certificate is much slower than the SW-SUDI. Here, CISCO_IDEVID_CMCA3_SUDI is the new SW-SUDI certificate.

Interactive Help

The Cisco Catalyst 9800 Series Wireless Controller GUI features an interactive help that walks you through the GUI and guides you through complex configurations.

You can start the interactive help in the following ways:

  • By hovering your cursor over the blue flap at the right-hand corner of a window in the GUI and clicking Interactive Help.

  • By clicking Walk-me Thru in the left pane of a window in the GUI.

  • By clicking Show me How displayed in the GUI. Clicking Show me How triggers a specific interactive help that is relevant to the context you are in.

    For instance, Show me How in Configure > AAA walks you through the various steps for configuring a RADIUS server. Choose Configuration> Wireless Setup > Advanced and click Show me How to trigger the interactive help that walks you through the steps relating to various kinds of authentication.

The following features have an associated interactive help:

  • Configuring AAA

  • Configuring FlexConnect Authentication

  • Configuring 802.1x Authentication

  • Configuring Local Web Authentication

  • Configuring OpenRoaming

  • Configuring Mesh APs

  1. device# configure terminal

  2. device(config)# line vty 50

    A best practice is to configure the service tcp-keepalives to monitor the TCP connection to the device.

  3. device(config)# service tcp-keepalives-in

  4. device(config)# service tcp-keepalives-out

Before You Upgrade

Ensure that you familiarize yourself with the following points before proceeding with the upgrade:


Caution


During controller upgrade or reboot, if route processor ports are connected to any Cisco switch, ensure that the route processor ports are not flapped (shut/no shut process). Otherwise, it may lead to a kernel crash.



Note


  • ISSU feature is supported only within and between major releases, for example, 17.3.x (within a release) and 17.3.x to 17.6.x (among major releases).

  • Controller upgrade from Cisco IOS XE Bengaluru 17.3.x to Cisco IOS XE Bengaluru 17.6.x or Cisco IOS XE Cupertino 17.9.x or later using ISSU may fail if the domain command is configured. Ensure that you run the no domain command before starting an ISSU upgrade because the domain command has been removed from Cisco IOS XE Bengaluru 17.6.x.

  • Controller upgrade from Cisco IOS XE Bengaluru 17.3.x to any release using ISSU may fail if the snmp-server enable traps hsrp command is configured. Ensure that you remove the snmp-server enable traps hsrp command from the configuration before starting an ISSU upgrade because the snmp-server enable traps hsrp command has been removed from Cisco IOS XE Bengaluru 17.4.x.

  • Controller upgrade to Cisco IOS XE Dublin 17.12.x from any prior release using ISSU may fail if the snmp-server enable traps license command is configured. Ensure that you remove the snmp-server enable traps license command from the configuration before starting an ISSU upgrade because the snmp-server enable traps license command has been removed from Cisco IOS XE Dublin 17.12.x.

  • Rolling AP upgrade, which is a part of the ISSU feature, is not supported for mesh APs.

  • Ensure that you add Authentication and Key Management (AKM) setting when you configure WPA3. In older releases, this scenario was not mandatory which resulted in an invalid configuration. However, from 17.9 and higher releases, this invalid scenario is detected and prevented.


Cisco Wave 2 APs may get into a boot loop when upgrading software over a WAN link. For more information, see: https://www.cisco.com/c/en/us/support/docs/wireless/catalyst-9800-series-wireless-controllers/220443-how-to-avoid-boot-loop-due-to-corrupted.html.

The following Wave 1 APs are not supported from 17.4 to 17.9.2, 17.10.x, 17.11.x, 17.13.x, and 17.14.x:

  • Cisco Aironet 1570 Series Access Point

  • Cisco Aironet 1700 Series Access Point

  • Cisco Aironet 2700 Series Access Point

  • Cisco Aironet 3700 Series Access Point


Note


  • Support for the above APs was reintroduced from Cisco IOS XE Cupertino 17.9.3.

  • Support for these APs does not extend beyond the normal product lifecycle support. Refer to the individual End-of-Support bulletins on Cisco.com.

  • Feature support is on parity with the 17.3.x release. Features introduced in 17.4.1 or later are not supported on these APs in the 17.9.3 release.

  • You can migrate directly to 17.9.3 from 17.3.x, where x=4c or later.


  • From Cisco IOS XE Dublin 17.10.x, Key Exchange and MAC algorithms like diffie-hellman-group14-sha1, hmac-sha1, hmac-sha2-256, and hmac-sha2-512 are not supported by default and it may impact some SSH clients that only support these algorithms. If required, you can add them manually. For information on manually adding these algorithms, see the SSH Algorithms for Common Criteria Certification document available at: https://www.cisco.com/c/en/us/td/docs/routers/ios/config/17-x/sec-vpn/b-security-vpn/m_sec-secure-shell-algorithm-ccc.html

  • If APs fail to detect the backup image after running the archive download-sw command, perform the following steps:

    1. Upload the image using the no-reload option of the archive download-sw command:

      Device# archive download-sw /no-reload tftp://<tftp_server_ip>/<image_name>
    2. Restart the CAPWAP process using capwap ap restart command. This allows the AP to use the correct backup image after the restart (reload is not required.)

      Device# capwap ap restart 

      Caution


      The AP will lose connection to the controller during the join process. When the AP joins the new controller, it will see a new image in the backup partition. So, the AP will not download a new image from the controller.


  • If the Cisco-IOS-XE-wireless-access-point-oper shows country operator as ZZ, the information is specific for countries supporting multiple regulatory domains. These records should only be accessed and referred to by such countries. For country-specific information, refer to the respective record using the country code.

  • You might observe a high Confd CPU when full synchronization occurs between NETCONF datastore and Cisco IOS configuration. This behavior is normal and is triggered by the line vty command.

  • From Cisco IOS XE Cupertino 17.7.1 onwards, for Cisco Catalyst 9800-CL Wireless Controller, ensure that you complete Resource Utilization Measurement (RUM) reporting and ensure that the ACK is made available on the product instance at least once. This is to ensure that correct and up-to-date usage information is reflected in the Cisco Smart Software Manager (CSSM).

  • Fragmentation lower than 1500 is not supported for the RADIUS packets generated by wireless clients in the Gi0 (OOB) interface.

  • Cisco IOS XE allows you to encrypt all the passwords used on the device. This includes user passwords and SSID passwords (PSK). For more information, see the "Password Encryption" section of the Cisco Catalyst 9800 Series Configuration Best Practices document.

  • While upgrading to Cisco IOS XE 17.3.x and later releases, if the ip http active-session-modules none command is enabled, you will not be able to access the controller GUI using HTTPS. To access the GUI using HTTPS, run the following commands in the order specified below:

    1. ip http session-module-list pkilist OPENRESTY_PKI

    2. ip http active-session-modules pkilist

  • Cisco Aironet 1815T OfficeExtend Access Point will be in local mode when connected to the controller. However, when it functions as a standalone AP, it gets converted to FlexConnect mode.

  • The Cisco Catalyst 9800-L Wireless Controller may fail to respond to the BREAK signals received on its console port during boot time, preventing users from getting to the ROMMON. This problem is observed on the controllers manufactured until November 2019, with the default config-register setting of 0x2102. This problem can be avoided if you set config-register to 0x2002. This problem is fixed in the 16.12(3r) ROMMON for Cisco Catalyst 9800-L Wireless Controller. For information about how to upgrade the ROMMON, see the Upgrading ROMMON for Cisco Catalyst 9800-L Wireless Controllers section of the Upgrading Field Programmable Hardware Devices for Cisco Catalyst 9800 Series Wireless Controllers document.

  • By default, the controller uses a TFTP block size value of 512, which is the lowest possible value. This default setting is used to ensure interoperability with legacy TFTP servers. If required, you can change the block size value to 8192 to speed up the transfer process, using the ip tftp blocksize command in global configuration mode.

  • We recommend that you configure the password encryption aes and the key config-key password-encrypt key commands to encrypt your password.

  • If the following error message is displayed after a reboot or system crash, we recommend that you regenerate the trustpoint certificate:
     ERR_SSL_VERSION_OR_CIPHER_MISMATCH

    Use the following commands in the order specified below to generate a new self-signed trustpoint certificate:

    1. device# configure terminal

    2. device(config)# no crypto pki trustpoint trustpoint_name

    3. device(config)# no ip http server

    4. device(config)# no ip http secure-server

    5. device(config)# ip http server

    6. device(config)# ip http secure-server

    7. device(config)# ip http authentication local/aaa

  • Do not deploy OVA files directly to VMware ESXi 6.5. We recommend that you use an OVF tool to deploy the OVA files.

  • Ensure that you remove the controller from Cisco Prime Infrastructure before disabling or enabling Netconf-YANG. Otherwise, the system may reload unexpectedly.

  • Unidirectional Link Detection (UDLD) protocol is not supported.

  • SIP media session snooping is not supported on FlexConnect local switching deployments.

  • The Cisco Catalyst 9800 Series Wireless Controllers (C9800-CL, C9800-L, C9800-40, and C9800-80) support a maximum of 14,000 leases with internal DHCP scope.

  • Configuring the mobility MAC address using the wireless mobility mac-address command is mandatory for both HA and 802.11r.

  • If you have Cisco Catalyst 9120 (E/I/P) and Cisco Catalyst 9130 (E) APs in your network and you want to downgrade, use only Cisco IOS XE Gibraltar 16.12.1t. Do not downgrade to Cisco IOS XE Gibraltar 16.12.1s.

  • The following SNMP variables are not supported:

    • CISCO-LWAPP-WLAN-MIB: cLWlanMdnsMode

    • CISCO-LWAPP-AP-MIB.my: cLApDot11IfRptncPresent, cLApDot11IfDartPresent

  • If you are upgrading from Cisco IOS XE Gibraltar 16.11.x or an earlier release, ensure that you unconfigure the advipservices boot-level licenses on both the active and standby controllers using the no license boot level advipservices command before the upgrade. Note that the license boot level advipservices command is not available in Cisco IOS XE Gibraltar 16.12.1s and 16.12.2s.

  • The Cisco Catalyst 9800 Series Wireless Controller has a service port that is referred to as GigabitEthernet 0 port.

    The following protocols and features are supported through this port:

    • Cisco Catalyst Center

    • Cisco Smart Software Manager

    • Cisco Prime Infrastructure

    • Telnet

    • Controller GUI

    • DNS

    • File transfer

    • GNMI

    • HTTP

    • HTTPS

    • LDAP

    • Licensing for Smart Licensing feature to communicate with CSSM

    • Netconf

    • NetFlow

    • NTP

    • RADIUS (including CoA)

    • Restconf

    • SNMP

    • SSH

    • SYSLOG

    • TACACS+

  • During device upgrade using GUI, if a switchover occurs, the session expires and the upgrade process gets terminated. As a result, the GUI cannot display the upgrade state or status.

  • From Cisco IOS XE Bengaluru 17.4.1 onwards, the telemetry solution provides a name for the receiver address instead of the IP address for telemetry data. This is an additional option. During the controller downgrade and subsequent upgrade, there is likely to be an issue—the upgrade version uses the newly named receivers, and these are not recognized in the downgrade. The new configuration gets rejected and fails in the subsequent upgrade. Configuration loss can be avoided when the upgrade or downgrade is performed from Cisco Catalyst Center.

  • From Cisco IOS XE Bengaluru 17.4.1 onwards, session timeout under the policy profile is supported.

  • Communication between Cisco Catalyst 9800 Series Wireless Controller and Cisco Prime Infrastructure uses different ports:

    • All the configurations and templates available in Cisco Prime Infrastructure are pushed through SNMP and CLI, using UDP port 161.

    • Operational data for controller is obtained over SNMP, using UDP port 162.

    • AP and client operational data leverage streaming telemetry:

      • Cisco Prime Infrastructure to controller: TCP port 830 is used by Cisco Prime Infrastructure to push the telemetry configuration to the controller (using NETCONF).

      • Controller to Cisco Prime Infrastructure: TCP port 20828 is used for Cisco IOS-XE 16.10.x and 16.11.x, and TCP port 20830 is used for Cisco IOS-XE 16.12.x, 17.1.x and later releases.

  • The Cisco Centralized Key Management (CCKM) feature is deprecated from Cisco IOS XE Dublin 17.10.x.

  • To migrate public IP address from 16.12.x to 17.x. ensure that you configure the service internal command. If you do not configure the service internal command, the IP address does not get carried forward.

  • RLAN support with Virtual Routing and Forwarding (VRF) is not available.

  • When you encounter the SNMP error SNMP_ERRORSTATUS_NOACCESS 6, it means that the specified SNMP variable is not accessible.

  • We recommend that you perform a controller reload whenever there is a change in the controller's clock time to reflect an earlier time.


Note


The DTLS version (DTLSv1.0) is deprecated for Cisco Aironet 1800 based on latest security policies. Therefore, any new out-of-box deployments of Cisco Aironet 1800 APs will fail to join the controller and you will get the following error message:

%APMGR_TRACE_MESSAGE-3-WLC_GEN_ERR: Chassis 1 R0/2: wncd: Error in AP Join, AP <AP-name>, 
mac:<MAC-address>Model AIR-AP1815W-D-K9, AP negotiated unexpected DTLS version v1.0

To onboard new Cisco Aironet 1800 APs and to establish a CAPWAP connection, explicitly set the DTLS version to 1.0 in the controller using the following configuration:


config terminal
ap dtls-version dtls_1_0
end

Note that setting the DTLS version to 1.0 affects all the existing AP CAPWAP connections. We recommend that you apply the configuration only during a maintenance window. After the APs download the new image and join the controller, ensure that you remove the configuration.


To upgrade the field programmable hardware devices for Cisco Catalyst 9800 Series Wireless Controllers, see Upgrading Field Programmable Hardware Devices for Cisco Catalyst 9800 Series Wireless Controllers.


Important


Before you begin a downgrade process, you must manually remove the configurations which are applicable in the current version but not in older version. Otherwise, you might encounter an unexpected behavior.

Upgrading the Controller Software

This section describes the various aspects of upgrading the controller software.

For information on the upgrade process and the methods to upgrade the Cisco Catalyst 9800 Series Wireless Controller software, see the "Upgrading the Cisco Catalyst 9800 Wireless Controller Software" chapter of the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide.

Finding the Software Version

The package files for the Cisco IOS XE software are stored in the system board flash device (flash:).

Use the show version privileged EXEC command to see the software version that is running on your controller.


Note


Although the show version output always shows the software image running on the controller, the model name shown at the end of the output is the factory configuration, and does not change if you upgrade the software license.

Use the show install summary privileged EXEC command to see the information about the active package.

Use the dir filesystem: privileged EXEC command to see the directory names of other software images that you have stored in flash memory.

Software Images

  • Release: Cisco IOS XE Dublin 17.11.x

  • Image Names (9800-80, 9800-40, and 9800-L):
