Behavior Change
-
System unresponsiveness and reloads are observed in Standby when image upgrades to Cisco IOS XE 17.15.1 in Cisco Catalyst CW9800M, and CW9800H1 and CW9800H2 Wireless Controllers. A switchover is initiated at the time of standby initialization.
This is a rare case scenario. You will need design changes to fix the issue.
-
From this release, the Mobility Tunnel UP/DOWN messages will be marked for severity level ALERT.
-
From this release, it is not possible to disable the 802.11h channel switch. The channel switch announcements (CSA) remain enabled at all times because they help clients when the APs announce the change from the current channel to a new channel, thereby reducing the number of reconnections.
-
The minimum memory requirement of the Cisco Catalyst 9800 Wireless Controller for Cloud - Ultra-Low Profile variant is increased from 4 GB to 6 GB.
-
From this release, the suiteb and suiteb-192 authentication and key management (AKMs) are decoupled from the GCMP128, GCMP256/CCMP256 and must be configured separately. When the controller is upgraded from a lower version to 17.15, WLANs configured with suiteb AKMs will be affected. If the controller downgrades from version 17.15 to a lower one, the WLANs enabled with only suiteb AKMs will remain operational, while the WLANs with multiple AKMs enabled will be operational without the suiteb-related AKMs.
-
From Cisco IOS XE 17.15.1, the default air pressure sample interval is changed from 30 seconds to 60 seconds. For example, if the duration is set to 10 minutes, the APs send 10 samples spaced at 60 seconds each.
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

The controller GUI uses Virtual Terminal (VTY) lines for processing HTTP requests. At times, when multiple connections are open, the default number of VTY lines of 15 set by the device might get exhausted. Therefore, we recommend that you increase the number of VTY lines to 50.
To increase the VTY lines in a device, run the following commands in the following order:
-
device# configure terminal
-
device(config)# line vty 50
A best practice is to configure the service tcp-keepalives to monitor the TCP connection to the device.
-
device(config)# service tcp-keepalives-in
-
device(config)# service tcp-keepalives-out
Before You Upgrade
Ensure that you familiarize yourself with the following points before proceeding with the upgrade:
Important |
The Cisco Catalyst 9800 Series Wireless Controller may experience an unexpected reload when CLI accounting is enabled and the wireless configuration is changed using the WebUI with an IPv6 address. The issue affects only wireless platforms. Workaround:
|
The Air Quality Sensor feature is disabled in Cisco IOS XE 17.15.1. Although, you may be able to view the Config-State (as Enabled), Admin-State (as Enabled), and Oper-Status (as Up), there will be no values sent from the Air Quality Sensor.
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. |
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, 17.14.x, and 17.15.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 |
|
-
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:
-
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>
-
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.
-
-
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:
-
ip http session-module-list pkilist OPENRESTY_PKI
-
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:
-
device# configure terminal
-
device(config)# no crypto pki trustpoint trustpoint_name
-
device(config)# no ip http server
-
device(config)# no ip http secure-server
-
device(config)# ip http server
-
device(config)# ip http secure-server
-
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
-
HTTP
-
HTTPS
-
Licensing for Smart Licensing feature to communicate with CSSM
-
SSH
-
-
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.
-
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.
-
-
-
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:
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:
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. |
-
When you downgrade an AP from a higher version to Cisco IOS XE Amsterdam 17.3.x, the AP will not be accessible through SSH or the console due to the denial of the enable password, when the AP has not yet joined a controller. If the AP joins a controller, then the AP becomes accessible without any password denial.

Upgrading the Controller Software
This section describes the various aspects of upgrading the controller software.
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.
