Description, Documentation Link and License Level Information

Boot Integrity Visibility

(C9200)

Allows Cisco's platform identity and software integrity information to be visible and actionable. Platform identity provides a platform’s manufacturing installed identity, and software integrity exposes boot integrity measurements that can be used to assess whether the platform has booted a trusted code.

(Network Essentials and Network Advantage)

Cisco TrustSec

(C9200)

Provides security improvements to Cisco network devices based on the capability to strongly identify users, hosts, and network devices within a network. TrustSec provides topology-independent and scalable access controls by uniquely classifying data traffic for a particular role. TrustSec ensures data confidentiality and integrity by establishing trust among authenticated peers and encrypting links with those peers.

See → Cisco TrustSec.

(Network Advantage)

Programmability

  • Model Driven Telemetry - gRPC Dial-Out

  • YANG Data Models

These programmability features were introduced in the release:

  • Model Driven Telemetry - gRPC Dial-Out—Expands existing Model Driven Telemetry capabilities with the addition of gRPC protocol support and Dial-Out (configured) telemetry subscriptions.

    (Network Essentials and Network Advantage)

  • YANG Data Models—For the list of Cisco IOS XE YANG models available with this release, navigate 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 changes that have been made in the release.

See → Programmability Configuration Guide, Cisco IOS XE Gibraltar 16.10.x.

Secure Storage of Encryption Keys and Passwords

Secures critical configuration, keys, and passwords by encrypting them. An instance-unique encryption key is stored in the hardware trust anchor to prevent it from being compromised. This feature is enabled on platforms that come with a hardware trust anchor, by default and is not supported on platforms that do not have a hardware trust anchor.

(Network Essentials and Network Advantage)

Simplified Factory Reset

Removes all customer specific data that has been added to the device since the time of its shipping. Data erased includes configurations, log files, boot variables, core files, and credentials.

(Network Essentials and Network Advantage)

Software Maintenance Upgrade (SMU)

The SMU package now supports patching of the public key infrastructure (PKI) component.

(DNA Advantage)

Serviceability

  • The debug eigrp address-family ipv4 command was introduced. It displays debugging information about Enhanced Interior Gateway Routing Protocol (EIGRP) address family.

  • The debug platform software fed switch active punt packet-capture command was introduced. It enables debugging of packets during high CPU utilization.

show ip ospf traffic neighbour and show ipv6 ospf traffic neighbour commands

The show ip ospf traffic neighbour and show ipv6 ospf traffic neighbour commands were introduced. They display Open Shortest Path First (OSPF) traffic statistics on a per-neighbor basis.

show logging commands

show platform commands

  • The show platform hardware fed switch forward interface command was enhanced to trace packets across a stack and also trace packets captured in a PCAP file.

  • The show platform software fed punt cpuq rates command was introduced. It displays the rate at which packets are punted, including the drops in the punted path.

  • The show platform software fed switch punt packet-capture display command was introduced. It displays packet information captured during high CPU utilization.

  • The show platform software process memory command was modified and the virtual size column was deleted from the output.

  • The show platform software thread list and show platform software process list commands outputs were modified. The size columns in the outputs display the Resident Set Size (RSS) in KB.

show processes commands

The show processes platform , show processes cpu platform , and show processes cpu platform history commands outputs were modified. The size columns in the outputs display the Resident Set Size (RSS) in KB.

show processes memory platform commands

  • show processes memory platform command was enhanced, the accounting keyword was added.

  • The show processes memory platform , show processes memory platform location , and show processes memory platform sorted commands were modified and the Total column was deleted from the output.

New on the Web UI

Web UI

  • Spanning Tree Protocol (STP) in Layer 2 configuration—Provides path redundancy to build a loop-free topology for Ethernet networks. Security mechanisms like bridge protocol data units (BPDU) Guard and BPDU Filtering provide further protection by ensuring a more stable network.

  • VLAN Trunk Protocol (VTP)—Reduces administration in a switched network. When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere.

Important Notes

Unsupported Features

  • IPsec VPN

  • Virtual Routing and Forwarding (VRF)-Aware web authentication

Complete List of Supported Features

For the complete list of features supported on a platform, see the Cisco Feature Navigator at https://www.cisco.com/go/cfn.

Accessing Hidden Commands

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 Comman 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.

Finding the Software Version

The package files for the Cisco IOS XE software are stored on the system board flash device (flash:).

You can use the show version privileged EXEC command to see the software version that is running on your switch.


Note

Although the show version output always shows the software image running on the switch, the model name shown at the end of this display is the factory configuration and does not change if you upgrade the software license.

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

Automatic Boot Loader Upgrade


Note

If Cisco Catalyst 9400 Series Supervisor 1 Module power is disconnected and reconnected within a 5-second window, the boot SPI may get corrupted.

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.


Scenario

Automatic Boot Loader Response

If you boot Cisco IOS XE Gibraltar 16.10.1 for the first time

The boot loader version may be upgraded to 16.6.2r [FC1]. For example:
ROM: IOS-XE ROMMON
BOOTLDR: System Bootstrap, Version 16.6.2r [FC1], RELEASE SOFTWARE (P)

If the automatic boot loader upgrade occurs, while booting, you will see the following on the console:

%IOSXEBOOT-4-BOOTLOADER_UPGRADE: (rp/0): ### BOOTLOADER_UPGRADE skipped

Complex Programmable Logic Device (CPLD) Upgrade

This refers to hardware-programmable firmware. The CPLD upgrade process is part of the automatic boot loader upgrade. The sequence of events is as follows:


Note

There are no FPGA or CPLD upgrades in Cisco IOS XE Gibraltar 16.10.1.


  1. The system copies mcnewfpgaclose.hdr and mcnewfpgaclose.img to the bootflash.

  2. The supervisor module then automatically reloads to enable the new boot loader.

  3. When the new boot loader boots up, the CPLD upgrade process starts automatically. The CPLD upgrade process takes approximately from 7 to 10 minutes. The supervisor will power cycle itself during the CPLD upgrade.

The following is sample output from a CPLD upgrade:

Step 5

Reload

  1. reload

    Use this command to reload the switch.

    Switch# reload
    
    
  2. boot flash:

    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 16.10.1 image on the device:
    Switch# show version
    Cisco IOS XE Software, Version 16.10.01
    Cisco IOS Software [Gibraltar], Catalyst L3 Switch Software (CAT9K_IOSXE), Version 16.10.1, RELEASE SOFTWARE (fc1)

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 16.10.1

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 Fuji 16.9.x or earlier releases.

The sample output in this section shows downgrade from Cisco IOS XE Gibraltar 16.10.1 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.

Step 4

Reload

  1. boot flash:

    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
    
    
    Note 
    When you downgrade the software image, the boot loader does not automatically downgrade. It remains updated.
  2. 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 Everest 16.6.2 image on the device:

Licensing

This section provides information about the licensing packages for features available on

License Levels

The software features available on fall under these base or add-on license levels.

Base Licenses

Add-On Licenses

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 Advantage

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.

  • Evaluation—a license that is not registered.

License Levels - Usage Guidelines

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 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.

See:

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 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.


How Upgrading or Downgrading Software Affects Smart Licensing

Smart Licensing is the default and only license management solution; all licenses are managed as Smart Licenses.

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 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.

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

Starting from , 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.

See:

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.

  • 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.

  • 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.

  • VLAN Restriction—It is advisable to have well-defined segregation while defining data and voice domain during switch configuration and to maintain a data VLAN different from voice VLAN across the switch stack. If the same VLAN is configured for data and voice domains on an interface, the resulting high CPU utilization might affect the device.

  • YANG data modeling limitation—A maximum of 20 simultaneous NETCONF sessions are supported.

Caveats

Caveats describe unexpected behavior in Cisco IOS-XE releases. Caveats 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.
