Cisco Catalyst 9800 Series comprises next-generation wireless controllers (controller) built for intent-based networking. The Catalyst 9800 Series Wireless Controllers are Cisco IOS XE-based and integrate the radio frequency (RF) capabilities from Cisco Aironet with the intent-based networking capabilities of Cisco IOS XE to create a best-in-class wireless experience for your organization.
The Catalyst 9800 wireless controllers are enterprise-ready to power your business-critical operations and transform end-customer experiences:
-
The controllers come with high availability (HA) and seamless software updates that are enabled by hot and cold patching. This keeps your clients and services on always, both during planned and unplanned events.
-
The controllers come with built-in security, including secure boot, run-time defenses, image signing, integrity verification, and hardware authenticity.
-
The controllers can be deployed anywhere to enable wireless connectivity, for example, on an on-premise device, on cloud (public or private), or embedded on a Cisco Catalyst switch or Catalyst access point (AP).
-
The controllers can be managed using Cisco Digital Network Architecture (DNA) Center, Programmability interfaces, for example, NETCONF and YANG, web-based GUI, or CLI.
-
The controllers are built on a modular operating system. Open and programmable APIs enable the automation of your Day 0 to Dayn network operations. Model-driven streaming telemetry provides deep insights into your network and client health.
The Catalyst 9800 Series Wireless Controllers are available in multiple form factors to cater to your deployment options:
-
Catalyst 9800 Series Wireless Controller Appliance
-
Catalyst 9800 Series Wireless Controller for Cloud
-
Catalyst 9800 Embedded Wireless Controller for a switch
Note |
All of the Cisco IOS-XE programmability-related topics on the Cisco Catalyst 9800 Wireless Controller are supported by DevNet, either through community-based support or through DevNet developer support. For more information, go to https://developer.cisco.com. |

Important Notes
-
The Cisco Catalyst 9800-L Wireless Controller may fail to respond to BREAK signals received on its console port during boot time preventing the user from getting to the ROMMON. This problem is observed on the controllers manufactured till November 2019, with the default config-register setting of 0x2102. This problem can be avoided if you set the config-register to 0x2002. This problem is fixed in the 16.12(3r) ROMMON for Cisco Catalyst 9800-L Wireless Controller. For steps on how to upgrade the ROMMON, see the Upgrading ROMMON for Cisco Catalyst 9800-L Wireless Controllers section of Upgrading Field Programmable Hardware Devices for Cisco Catalyst 9800 Series Wireless Controllers.
-
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. However, you can manually change the block size value to 8192 K using the ip tftp blocksize command in global configuration mode to speed up the transfer process.
-
We recommend that you configure the password encryption aes and the key config-key password-encrypt key commands to encrypt your password.
-
The features and functions that work on IPv4 networks with IPv4 addresses also works on IPv6 networks with IPv6 addresses. For a list of unsupported features, see the Unsupported Features section of the Native IPv6 feature.
-
If you encounter ERR_SSL_VERSION_OR_CIPHER_MISMATCH error from the GUI after a reboot or system crash, we recommend that you regenerate the trustpoint certificate.
The procedure to generate a new self signed trustpoint is as follows:
configure terminal no crypto pki trustpoint <trustpoint_name> no ip http server no ip http secure-server ip http server ip http secure-server ip http authentication <local/aaa> ! use local or aaa as applicable.
-
SNMPv3 user configuration is not reflected in the running configuration. Only SNMPv3 group configuration is visible.
-
The Cisco Catalyst 9800 Series Wireless Controller has a service port, which is referred to as GigabitEthernet 0 port. You cannot use this port for RADIUS, SNMP, DNAC Telemetry, and other communications.
The service port only supports the following IP protocols:
-
HTTP
-
HTTPS
-
SSH
-
Licensing for Smart Licensing feature to communicate with CSSM
-

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 on 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 this 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.
You can also use the dir filesystem: privileged EXEC command to see the directory names of other software images that you have stored in flash memory.

Caveats
Caveats describe unexpected behavior in Cisco IOS releases. Caveats that are listed as Open in a prior release are carried forward to the next release as either Open or Resolved.
Note |
All incremental releases will cover fixes from the current release. |
Cisco Bug Search Tool
The Cisco Bug Search Tool (BST) allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The BST is designed to improve the effectiveness in network risk management and device troubleshooting. The tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.
