Behavior Changes
Behavior Change for Cisco IOS XE 17.12.6
-
Controller displayed out-of-order packet issue with fragmented packets when Auto QoS was enabled. When a client tries to connect to an EAP-TLS-based SSID, during the certificate exchange, the client sends its device certificate. If the certificate is fragmented because it exceeds the MTU (1500), the fragments are observed to be sent out-of-order from the controller when Auto QoS is enabled.
With the change in behavior, the fragments are classified and applied with default action. For workarounds, refer to CSCwo97886.
-
The ip proxy-arp configuration is disabled by default under VLAN interfaces for the controller.
-
For Cisco Aironet 1815T Series AP, from Cisco IOS XE 17.12.x,
.../storage/config.oeap
was created beforehand as long as the AP is in OEAP mode.With the change in behavior, once the AP boots in FlexConnect OEAP mode, it switches on the default OEAP DHCP server (dhcp0) as day 1 configuration.
-
In the Mobility Data DTLS tunnel, DTLS encryption was enabled on Peer1 and disabled on Peer2, causing the mobility tunnel to be up. However, with the change in behavior, DTLS encryption is enabled on Peer1 and disabled on Peer2, causing the mobility tunnel to go down.
-
The maximum supported RFIDs per WNCD for any platform has been increased to greater than 9601 RFIDs. The new value of the maximum RFID is platform dependent.
-
When source-interface was configured under mDNS globally, this source-interface was chosen to send out mDNS packets. When the source-interface was not configured, then, the controller used wireless management interface WMI) to send out the mDNS packets.
With the change in behavior, when source-interface is configured, the controller uses this configured source-interface to send out mDNS packets. When the source-interface is not configured,
-
Option 1: Use SVI as the source-interface (if SVI of the intended VLAN is configured).
-
Option 2: If option 1 fails, use the default Wireless Management Interface (WMI).
-
-
Authentication for AP with EAP fails if the password is more than 31 characters. With the change in behavior, password with more than 31 characters works successfully.
-
When you apply an AP tag configuration, ensure that the number of APs associated with a non-default site tag does not exceed the platform limit. The system allows these configurations, but APs exceeding the limit cannot join the network.
The configuration validator now checks for this condition and when more APs than the platform limit are associated with the same site tag, the configuration is not rejected.
-
Cisco Catalyst 9105 AP bridges the RLAN traffic to a wrong VLAN.
To prevent this issue:
-
Delete any unused VLAN from the FlexConnect profile.
-
Run the capwap ap erase all command to clear the AP cache.
-
Behavior Change for Cisco IOS XE 17.12.1 to 17.12.5
-
From Cisco IOS XE Dublin 17.12.2 onwards, 6-GHz radio band is not supported for Honduras country code (HN) in Cisco Catalyst 9136, 9162, 9164, and 9166 Series APs.
-
From Cisco IOS XE Dublin 17.12.x, the Express Wi-Fi by Facebook feature is not supported.
-
From Cisco IOS XE Dublin 17.12.2, the show running-config wlan command is modified. The wlan_name variable is removed.
-
The following command output is modified for the KPIs for AP Health Via the Controller and AP feature:
-
show ap name config general
-
-
The following command outputs are modified for the Configuring Transition Mode and Pure WPA3 (6 GHz) on the Same WLAN Profile feature:
-
show wlan all
-
show wlan id
-
show wlan name
-
show wlan summary
-
-
WPA2 should be disabled while WPA3, PMF and dot11ax are enabled to broadcast WLAN exclusively on 6-GHz band. WPA2 can be enabled when broadcasting on other bands, such as 2.4 and 5-GHz.
-
The inner MAC filtering feature of Embedded Packet Capture (EPC), captures CAPWAP data fragments and CAPWAP control not filtered by MAC.
-
When wireless interface is not available, the RMI +RP configuration on the Web UI is disabled.
-
From this release, the bssid-neighbor-stats interval value has been changed from 1 to180 seconds to 30 to 600 seconds. The default value is 180 seconds.
-
From this release, the default console baud rate of the 802.11AX APs is changed from 9600 bps to 115200 bps.
-
Both internal and external APs in NAT deployments must use different AP join profiles when CAPWAP Discovery Private and Public are enabled separately. This is applicable to APs upgraded to Cisco IOS XE Dublin 17.12.x and later.
-
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.
-
From Cisco IOS XE Dublin 17.12.x onwards, in dual 5-GHz scenarios for 6-GHz capable APs in India country code (IN), the slot2 BSSID count transition is corrected from 7 to 0. Previously, it transitioned incorrectly from 7 to F. Check CSCwo59295 for more details.

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:
-
When you upgrade from Cisco IOS XE 17.9.5 or 17.12.2 to Cisco IOS XE 17.15.x, the controller WebUI does not support images greater than 1.5 GB.
Workaround:
-
Upgrade using the CLI commands, or,
-
Upgrade to a fixed release first, and then upgrade to 17.15.x.
-
-
When you upgrade from Cisco IOS XE Dublin 17.12.3 to 17.12.4 or Cisco IOS XE 17.15.1, the Cisco Catalyst Wi-Fi 6 APs fail to upgrade the AP image.
Workaround:
-
Reboot the impacted APs through the power cycle.
For more information, see CSCwm08044
-
![]() 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 |
|
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

-
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 was deprecated in Cisco IOS XE 17.10.x, but currently remains supported. However, support for CCKM will be removed in a future release. Therefore, we recommend that you migrate to Fast Transition (FT) with 802.1X authentication and validate the configuration with supported key caching mechanisms.
-
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.
