Release Notes for Cisco Catalyst 9400 Series Switches, Cisco IOS XE Gibraltar 16.12.x

Introduction

Cisco Catalyst 9400 Series Switches are Cisco’s leading modular enterprise switching access platform and have been purpose-built to address emerging trends of Security, IoT, Mobility, and Cloud.

They deliver complete convergence with the rest of the Cisco Catalyst 9000 Series Switches in terms of ASIC architecture with a Unified Access Data Plane (UADP) 2.0. The platform runs an Open Cisco IOS XE that supports model driven programmability, has the capacity to host containers, and run 3rd party applications and scripts natively within the switch (by virtue of x86 CPU architecture, local storage, and a higher memory footprint). This series forms the foundational building block for SD-Access, which is Cisco’s lead enterprise architecture.

Cisco Catalyst 9400 Series Switches are enterprise optimized with a dual-serviceable fan tray design, side to side airflow, and are closet-friendly with a16-inch depth

Accessing Hidden Commands

Starting with Cisco IOS XE Fuji 16.8.1a, as an improved security measure, the way in which hidden commands can be accessed has changed.

Hidden commands have always been present in Cisco IOS XE, but were not equipped with CLI help. This means that entering enter a question mark (?) at the system prompt did not display the list of available commands. Such hidden commands are only meant to assist Cisco TAC in advanced troubleshooting and are therefore not documented. For more information about CLI help, see the Using the Command-Line InterfaceUnderstanding the Help System chapter of the Command Reference document.

Hidden commands are available under:

  • Category 1—Hidden commands in privileged or User EXEC mode. Begin by entering the service internal command to access these commands.

  • Category 2—Hidden commands in one of the configuration modes (global, interface and so on). These commands do not require the service internal command.

Further, the following applies to hidden commands under Category 1 and 2:

  • The commands have CLI help. Entering enter a question mark (?) at the system prompt displays the list of available commands.

    Note: For Category 1, enter the service internal command before you enter the question mark; you do not have to do this for Category 2.

  • The system generates a %PARSER-5-HIDDEN syslog message when the command is used. For example:
    *Feb 14 10:44:37.917: %PARSER-5-HIDDEN: Warning!!! 'show processes memory old-header ' is a hidden command. 
    Use of this command is not recommended/supported and will be removed in future.
    
    

Apart from category 1 and 2, there remain internal commands displayed on the CLI, for which the system does NOT generate the %PARSER-5-HIDDEN syslog message.


Important

We recommend that you use any hidden command only under TAC supervision.

If you find that you are using a hidden command, open a TAC case for help with finding another way of collecting the same information as the hidden command (for a hidden EXEC mode command), or to configure the same functionality (for a hidden configuration mode command) using non-hidden commands.

Automatic Boot Loader Upgrade


Caution

You must comply with these cautionary guidelines during an upgrade:

  • Do not power cycle your switch.

  • Do not disconnect power or remove the supervisor module.

  • Do not perform an online insertion and replacement (OIR) of either supervisor (in a High Availability setup), if one of the supervisor modules in the chassis is in the process of a bootloader upgrade or when the switch is booting up.

  • Do not perform an OIR of a switching module (linecard) when the switch is booting up.



Note

Disconnecting and reconnecting power to a Cisco Catalyst 9400 Series Supervisor 1 Module within a 5-second window, can corrupt the boot SPI.


Scenario

Upgrading in Install Mode

Follow these instructions to upgrade from one release to another, in install mode. To perform a software image upgrade, you must be booted into IOS via boot flash:packages.conf .

Before you begin

Note that you can use this procedure for the following upgrade scenarios.

When upgrading from ...

Permitted Supervisor Setup

(Applies to the release you are upgrading from)

First upgrade to...

To upgrade to ...

Cisco IOS XE Everest 16.6.14

Upgrade a single supervisor, and complete the boot loader and CPLD upgrade. After completing the first supervisor upgrade, remove and swap in the second supervisor. After both supervisors are upgraded, they can be inserted and booted in a high availability setup.

Note 
Do not simultaneously upgrade dual supervisors from Cisco IOS XE Everest 16.6.1 to a later release. Doing so may cause hardware damage.

Cisco IOS XE Everest 16.6.3

Follow the upgrade steps as in the Release Notes for Cisco Catalyst 9400 Series Switches, Cisco IOS XE Everest 16.6.x → Upgrading the Switch Software → Upgrading in Install Mode

Cisco IOS XE Gibraltar 16.12.1c

Cisco IOS XE Everest 16.6.2 and later releases

This procedure automatically copies the images to both active and standby supervisor modules. Both supervisor modules are simultaneously upgraded.

Not applicable

4

When upgrading from Cisco IOS XE Everest 16.6.1 to a later release, the upgrade may take a long time, and the system will reset three times due to rommon and complex programmable logic device (CPLD) upgrade. Stateful switchover is supported from Cisco IOS XE Everest 16.6.2


Caution

  • Do not power cycle your switch during an upgrade.

  • Do not disconnect power or remove the supervisor module during an upgrade.

  • Do not perform an online insertion and replacement (OIR) of either supervisor (in a High Availability setup), if one of the supervisor modules in the chassis is in the process of a bootloader upgrade or when the switch is booting up.

  • Do not perform OIR of a switching module (linecard) when the switch is booting up.


The sample output in this section displays upgrade from Cisco IOS XE Everest 16.6.3 to Cisco IOS XE Gibraltar 16.12.1c using install commands.

    If your switches are configured with auto boot, then the stack will automatically boot up with the new image. If not, you can manually boot flash:packages.conf
    Switch: boot flash:packages.conf
    
    
  3. show version

    After the image boots up, use this command to verify the version of the new image.

    Note 
    When you boot the new image, the boot loader is automatically updated, but the new bootloader version is not displayed in the output until the next reload.
    The following sample output of the show version command displays the Cisco IOS XE Gibraltar 16.12.1c image on the device:
    Switch# show version

Downgrading in Install Mode

Follow these instructions to downgrade from one release to another, in install mode. To perform a software image downgrade, you must be booted into IOS via boot flash:packages.conf .

Before you begin

Note that you can use this procedure for the following downgrade scenarios:

When downgrading from ...

Permitted Supervisor Setup

(Applies to the release you are downgrading from)

To ...

Cisco IOS XE Gibraltar 16.12.1c

This procedure automatically copies the images to both active and standby supervisor modules. Both supervisor modules are simultaneously downgraded.

Note 

Do not perform an Online Removal and Replacement (OIR) of either supervisor module during the process.

Cisco IOS XE Gibraltar 16.11.x or earlier releases.

The sample output in this section shows downgrade from Cisco IOS XE Gibraltar 16.12.1c to Cisco IOS XE Everest 16.6.2, using install commands.


Important

New hardware modules (supervisors or line card modules) that are introduced in a release cannot be downgraded. The release in which a module is introduced is the minimum software version for that model. We recommend upgrading all existing hardware to the same release as the latest hardware.

Procedure


Step 1

Clean Up

  1. install remove inactive

    Use this command to clean up old installation files in case of insufficient space. Ensure that you have at least 1GB of space in flash to expand a new image.

Upgrading the Complex Programmable Logic Device Version

This refers to hardware-programmable firmware. The Complex Programmable Logic Device (CPLD) version upgrade process must be completed after upgrading the software image.


Important

Firmware upgrades are required for Cisco IOS XE Gibraltar 16.12.x.

CPLD version: 19032905


Upgrading the CPLD Version: High Availability Setup

Beginning in the privileged EXEC mode, complete the following steps:

Before you begin

When performing the CPLD version upgrade as shown, the show platform command can be used to confirm the CPLD version after the upgrade. This command output shows the CPLD version on all modules. However, the CPLD upgrade only applies to the supervisors, not the line cards. The line cards CPLD version is a cosmetic display. After the upgrade is completed in a high availability setup, the supervisors will be upgraded, but the line cards will still show the old CPLD version. The version mismatch between the supervisors and line cards is expected until a chassis reload.

Procedure

Step 1

Upgrade the CPLD Version of the standby supervisor module

Enter the following commands on the active supervisor:

  1. Device# configure terminal

  2. Device(config)# service internal

  3. Device(config)# exit

  4. Device# upgrade hw-programmable cpld filename bootflash: rp standby

The standby supervisor module reloads automatically and the upgrade occurs in ROMMON. During the upgrade, the supervisor module automatically power cycles and remains inactive for approximately 5 minutes.

Wait until the standby supervisor module boots up and the SSO has formed (HOT) before you proceed to the next step; this takes approximately 17 minutes.

Step 2

Perform a switch over

  1. Device# redundancy force-switchover

This causes the standby supervisor (on which you have completed the CPLD upgrade in Step 1) to become the active supervisor module

Step 3

Upgrade the CPLD Version of the new standby supervisor module

Repeat Step 1 and all its substeps.

Note 

Do not operate an HA system with mismatched FPGA versions. FPGA version should be upgraded on both the supervisors one at a time.


Upgrading the CPLD Version: Cisco StackWise Virtual Setup

Beginning in the privileged EXEC mode, complete the following steps:

Procedure

Step 1

Upgrade the CPLD version of the standby supervisor module

Enter the following commands on the active supervisor:

  1. Device# configure terminal

  2. Device(config)# service internal

  3. Device(config)# exit

  4. Device# upgrade hw-programmable cpld filename bootflash: rp standby

Step 2

Reload the standby supervisor module

  1. Device# redundancy reload peer

The upgrade occurs in ROMMON. During the upgrade, the supervisor module automatically power cycles and remains inactive for approximately 5 minutes.

Wait until the standby supervisor module boots up and the SSO has formed (HOT) before you proceed to the next step; this takes approximately 17 minutes.

Step 3

Perform a switch over

  1. Device# redundancy force-switchover

This causes the standby supervisor (on which you have completed the CPLD upgrade in step 1) to become the active supervisor module

Step 4

Upgrade the CPLD version of the new standby supervisor module

Perfom Steps 1 and 2, including all substeps, on the new standby supervisor module


Upgrading the CPLD Version: Single Supervisor Module Setup

Beginning in the privileged EXEC mode, complete the following steps:

Procedure

Upgrade the CPLD version of the active supervisor module

Enter the following commands on the active supervisor:

  1. Device# configure terminal

  2. Device(config)# service internal

  3. Device(config)# exit

  4. Device# upgrade hw-programmable cpld filename bootflash: rp active

The supervisor module reloads automatically and the upgrade occurs in ROMMON. During the upgrade, the supervisor module automatically power cycles and remains inactive for approximately 5 minutes.


Example: CPLD Upgrade in a High Availability Setup

The sample output here shows the CPLD upgrade process in a High Availability setup:

  1. Boot Cisco IOS XE Gibraltar 16.12.1; the bootloader upgrades automatically:

    
    %IOSXEBOOT-4-BOOTLOADER_UPGRADE: (rp/0): boot loader upgrade successful

Licensing

This section provides information about the licensing packages for features available on Cisco Catalyst 9000 Series Switches.

License Levels

The software features available on Cisco Catalyst 9400 Series Switches fall under these base or add-on license levels.

Base Licenses

  • Network Essentials

  • Network Advantage—Includes features available with the Network Essentials license and more.

Add-On Licenses

Add-On Licenses require a Network Essentials or Network Advantage as a pre-requisite. The features available with add-on license levels provide Cisco innovations on the switch, as well as on the Cisco Digital Network Architecture Center (Cisco DNA Center).

  • DNA Essentials

  • DNA Advantage— Includes features available with the DNA Essentials license and more.

To find information about platform support and to know which license levels a feature is available with, use Cisco Feature Navigator. To access Cisco Feature Navigator, go to https://cfnng.cisco.com. An account on cisco.com is not required.

License Types

The following license types are available:

  • Permanent—for a license level, and without an expiration date.

  • Term—for a license level, and for a three, five, or seven year period.

  • Evaluation—a license that is not registered.

License Levels - Usage Guidelines

  • Base licenses (Network Essentials and Network-Advantage) are ordered and fulfilled only with a permanent license type.

  • Add-on licenses (DNA Essentials and DNA Advantage) are ordered and fulfilled only with a term license type.

  • An add-on license level is included when you choose a network license level. If you use DNA features, renew the license before term expiry, to continue using it, or deactivate the add-on license and then reload the switch to continue operating with the base license capabilities.

  • When ordering an add-on license with a base license, note the combinations that are permitted and those that are not permitted:

    Table 1. Permitted Combinations

    DNA Essentials

    DNA Advantage

    Network Essentials

    Yes

    No

    Network Advantage

    Yes5

    Yes

    5 You will be able to purchase this combination only at the time of the DNA license renewal and not when you purchase DNA-Essentials the first time.
  • Evaluation licenses cannot be ordered. They are not tracked via Cisco Smart Software Manager and expire after a 90-day period. Evaluation licenses can be used only once on the switch and cannot be regenerated. Warning system messages about an evaluation license expiry are generated only 275 days after expiration and every week thereafter. An expired evaluation license cannot be reactivated after reload. This applies only to Smart Licensing. The notion of evaluation licenses does not apply to Smart Licensing Using Policy.

Cisco Smart Licensing

Cisco Smart Licensing is a flexible licensing model that provides you with an easier, faster, and more consistent way to purchase and manage software across the Cisco portfolio and across your organization. And it’s secure – you control what users can access. With Smart Licensing you get:

  • Easy Activation: Smart Licensing establishes a pool of software licenses that can be used across the entire organization—no more PAKs (Product Activation Keys).

  • Unified Management: My Cisco Entitlements (MCE) provides a complete view into all of your Cisco products and services in an easy-to-use portal, so you always know what you have and what you are using.

  • License Flexibility: Your software is not node-locked to your hardware, so you can easily use and transfer licenses as needed.

To use Smart Licensing, you must first set up a Smart Account on Cisco Software Central (http://software.cisco.com).


Important

Cisco Smart Licensing is the default and the only available method to manage licenses.

For a more detailed overview on Cisco Licensing, go to cisco.com/go/licensingguide.

Deploying Smart Licensing

The following provides a process overview of a day 0 to day N deployment directly initiated from a device that is running Cisco IOS XE Fuji 16.9.1 or later releases. Links to the configuration guide provide detailed information to help you complete each one of the smaller tasks.

Procedure

Step 1

Begin by establishing a connection from your network to Cisco Smart Software Manager on cisco.com.

In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Connecting to CSSM

Step 2

Create and activate your Smart Account, or login if you already have one.

To create and activate Smart Account, go to Cisco Software Central → Create Smart Accounts. Only authorized users can activate the Smart Account.

Step 3

Complete the Cisco Smart Software Manager set up.

  1. Accept the Smart Software Licensing Agreement.

  2. Set up the required number of Virtual Accounts, users and access rights for the virtual account users.

    Virtual accounts help you organize licenses by business unit, product type, IT group, and so on.

  3. Generate the registration token in the Cisco Smart Software Manager portal and register your device with the token.

    In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Registering the Device in CSSM


With this,

  • The device is now in an authorized state and ready to use.

  • The licenses that you have purchased are displayed in your Smart Account.

Using Smart Licensing on an Out-of-the-Box Device

Starting from Cisco IOS XE Fuji 16.9.1, if an out-of-the-box device has the software version factory-provisioned, all licenses on such a device remain in evaluation mode until registered in Cisco Smart Software Manager.

In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Registering the Device in CSSM

How Upgrading or Downgrading Software Affects Smart Licensing

Starting from Cisco IOS XE Fuji 16.9.1, Smart Licensing is the default and only license management solution; all licenses are managed as Smart Licenses.


Important

Starting from Cisco IOS XE Fuji 16.9.1, the Right-To-Use (RTU) licensing mode is deprecated, and the associated license right-to-use command is no longer available on the CLI.

Note how upgrading to a release that supports Smart Licensing or moving to a release that does not support Smart Licensing affects licenses on a device:

  • When you upgrade from an earlier release to one that supports Smart Licensing—all existing licenses remain in evaluation mode until registered in Cisco Smart Software Manager. After registration, they are made available in your Smart Account.

    In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Registering the Device in CSSM

  • When you downgrade to a release where Smart Licensing is not supported—all smart licenses on the device are converted to traditional licenses and all smart licensing information on the device is removed.

Scaling Guidelines

Limitations and Restrictions

  • Control Plane Policing (CoPP)—The show run command does not display information about classes configured under system-cpp policy, when they are left at default values. Use the show policy-map system-cpp-policy or the show policy-map control-plane commands in privileged EXEC mode instead.

  • Cisco TrustSec restrictions—Cisco TrustSec can be configured only on physical interfaces, not on logical interfaces.

  • Flexible NetFlow limitations

    • You cannot configure NetFlow export using the Ethernet Management port (GigabitEthernet0/0).

    • You can not configure a flow monitor on logical interfaces, such as layer 2 port-channels, loopback, tunnels.

    • You can not configure multiple flow monitors of same type (ipv4, ipv6 or datalink) on the same interface for same direction.

  • Hardware limitations—When you use Cisco QSFP-4SFP10G-CUxM Direct-Attach Copper Cables, autonegotiation is enabled by default. If the other end of the line does not support autonegotation, the link does not come up.

  • Interoperability limitations—When you use Cisco QSFP-4SFP10G-CUxM Direct-Attach Copper Cables, if one end of the 40G link is a Catalyst 9400 Series Switch and the other end is a Catalyst 9500 Series Switch, the link does not come up, or comes up on one side and stays down on the other. To avoid this interoperability issue between devices, apply the the speed nonegotiate command on the Catalyst 9500 Series Switch interface. This command disables autonegotiation and brings the link up. To restore autonegotiation, use the no speed nonegotiation command.

  • In-Service Software Upgrade (ISSU)

    • ISSU from Cisco IOS XE Fuji 16.9.x to Cisco IOS XE Gibraltar 16.10.x or to Cisco IOS XE Gibraltar 16.11.x is not supported. This applies to both a single and dual supervisor module setup.

    • While performing ISSU from Cisco IOS XE Fuji 16.9.x to Cisco IOS XE Gibraltar 16.12.x, if interface-id snmp-if-index command is not configured with OSPFv3, packet loss can occur. Configure the interface-id snmp-if-index command either during the maintenance window or after isolating the device (by using maintenance mode feature) from the network before doing the ISSU.

    • While ISSU allows you to perform upgrades with zero downtime, we recommend you to do so during a maintenance window only.

    • If a new feature introduced in a software release requires a change in configuration, the feature should not be enabled during ISSU.

    • If a feature is not available in the downgraded version of a software image, the feature should be disabled before initiating ISSU.

  • Memory leak—When a logging discriminator is configured and applied to a device, memory leak is seen under heavy syslog or debug output. The rate of the leak is dependent on the quantity of logs produced. In extreme cases, the device may fail. As a workaround, disable the logging discriminator on the device.

  • No service password recovery—With ROMMON versions R16.6.1r and R16.6.2r, the 'no service password-recovery' feature is not available.

  • QoS restrictions

    • When configuring QoS queuing policy, the sum of the queuing buffer should not exceed 100%.

    • For QoS policies, only switched virtual interfaces (SVI) are supported for logical interfaces.

    • QoS policies are not supported for port-channel interfaces, tunnel interfaces, and other logical interfaces.

  • Redundancy—The supervisor module (hardware) supports redundancy. Software redundancy is supported starting with Cisco IOS XE Everest 16.6.2. However, the associated route processor redundancy (RPR) feature is not supported.

    Before performing a switchover, use the show redundancy , show platform , and show platform software iomd redundancy commands to ensure that both the SSOs have formed and that the IOMD process is completed.

    In the following sample output for the show redundancy , note that both the SSOs have formed.

  • With bootloader version 16.6.2r, you cannot access the M.2 SATA SSD drive at the ROMMON prompt (rommon> dir disk0). The system displays an error message indicating that the corresponding file system protocol is not found on the device. The only way to access the drive when on bootloader version 16.6.2r, is through the Cisco IOS prompt, after boot up.

  • Secure Shell (SSH)

    • Use SSH Version 2. SSH Version 1 is not supported.

    • When the device is running SCP and SSH cryptographic operations, expect high CPU until the SCP read process is completed. SCP supports file transfers between hosts on a network and uses SSH for the transfer.

      Since SCP and SSH operations are currently not supported on the hardware crypto engine, running encryption and decryption process in software causes high CPU. The SCP and SSH processes can show as much as 40 or 50 percent CPU usage, but they do not cause the device to shutdown.

  • TACACS legacy command: Do not configure the legacy tacacs-server host command; this command is deprecated. If the software version running on your device is Cisco IOS XE Gibraltar 16.12.2 or a later release, using the legacy command can cause authentication failures. Use the tacacs server command in global configuration mode.

  • Uplink Symmetry—When a redundant supervisor module is inserted, we recommend that you have symmetric uplinks, to minimize packet loss during a switchover.

    Uplinks are said to be in symmetry when the same interface on both supervisor modules have the same type of transceiver module. For example, a TenGigabitEthernet interface with no transceiver installed operates at a default 10G mode; if the matching interface of the other supervisor has a 10G transceiver, then they are in symmetry. Symmetry provides the best SWO packet loss and user experience.

    Asymmetric uplinks have at least one or more pairs of interfaces in one supervisor not matching the transceiver speed of the other supervisor.

  • USB Authentication—When you connect a Cisco USB drive to the switch, the switch tries to authenticate the drive against an existing encrypted preshared key. Since the USB drive does not send a key for authentication, the following message is displayed on the console when you enter password encryption aes command:
    Device(config)# password encryption aes
    Master key change notification called without new or old key
  • YANG data modeling limitation—A maximum of 20 simultaneous NETCONF sessions are supported.

  • Embedded Event Manager—Identity event detector is not supported on Embedded Event Manager.
