Release Notes for Cisco Catalyst 9800 Series Wireless Controller, Cisco IOS XE Gibraltar 16.10.1e

Introduction to Cisco Catalyst 9800 Series Wireless Controllers

Cisco Catalyst 9800 Series Wireless Controllers are next-generation wireless controllers built for intent-based networking. The Catalyst 9800 Series 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 switch.

  • The controllers can be managed using Cisco DNA Center, Programmability interfaces (for example, NETCONF/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-n 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 Switch

YANG Data Models

For the complete list of Cisco IOS XE YANG models available with this release, go to https://github.com/YangModels/yang/tree/master/vendor/cisco/xe/16101. Revision statements embedded in the YANG files indicate if there has been a model revision. The README.md file in the same GitHub location highlights the changes that have been made in this release.

Important Notes

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.

Supported Hardware

The following table lists the supported Cisco Catalyst 9800 Series Wireless Controller hardware models and the default license levels they are delivered with. For information about the available license levels, see section License Levels.

The Base PIDs are the model numbers of the controller.

The Bundled PIDs indicate the orderable part numbers for the Base PIDs that are bundled with a particular network module. Entering the show version , show module , or show inventory command on such a controller (bundled PID), displays its Base PID.

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 might have stored in flash memory.

Software Images

  • Release—Cisco IOS XE Gibraltar 16.10.1e

  • Image—Universal

  • File Name—C9800-universalk9_wlc.16.10.01e.SPA.bin

Software Installation Commands

Cisco IOS XE Gibraltar 16.10.1e

To install and activate a specified file, and to commit changes to be persistent across reloads, run the following command:

device# install add file filename [ activate| commit]

To separately install, activate, commit, abort, or remove the installation file, run the following command:

device# install ?

add file tftp: filename

Copies the install file package from a remote location to a device, and performs a compatibility check for the platform and image versions.

activate[ auto-abort-timer]

Activates the file and reloads the device. The auto-abort-timer keyword automatically rolls back image activation.

commit

Makes changes that are persistent over reloads.

rollback to committed

Rolls back the update to the last committed version.

abort

Aborts file activation, and rolls back to the version that was running before the current installation procedure started.

remove

Deletes all unused and inactive software installation files.

Licensing

This section provides information about the licensing packages for the features that are available in the Cisco Catalyst 9800 Series Wireless Controller.

The software features that are available on the controller fall under these license categories:

  • AIR DNA Essentials (AIR-DNA-E)

  • AIR DNA Advantage (AIR-DNA-A) (Includes the features that are available with the Cisco DNA Essentials license and more.)


    Note

    The controller starts with AIR-DNA-A as the default. Any change in the license level requires a reboot.


Base Licenses

Base licenses are perpetual licenses and can be used even after the expiry of Air-DNA-A and AIR-DNA-E. Base licenses include:

  • AIR Network Essentials (AIR-NE)

  • AIR Network Advantage (AIR-NA) (Includes the features that are available in the Network Essentials license.)

License Term

The licenses are available for a three, five, or seven-year periods.

Guidelines and Restrictions

  • AP connection over network address translation (NAT) and port address translation (PAT) is not supported.

  • Mobility NAT is not supported.

  • Firefox Version 63.x is not supported.

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

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

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.

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.
