Release Notes for Cisco Catalyst 9500 Series Switches, Cisco IOS XE Fuji 16.9.x

Introduction

Cisco Catalyst 9500 Series Switches and Cisco Catalyst 9500 Series Switches - High Performance are Cisco's lead, fixed core and aggregation enterprise switching platforms. They have been purpose-built to address emerging trends of Security, IoT, Mobility, and Cloud.

They deliver complete convergence in terms of ASIC architecture with Unified Access Data Plane (UADP) 2.0 on Cisco Catalyst 9500 Series Switches and UADP 3.0 on Cisco Catalyst 9500 Series Switches - High Performance. 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). The series forms the foundational building block for SD-Access, which is Cisco’s lead enterprise architecture.


Note

With the introduction of the High Performance models in the series, there may be differences in the supported and unsupported features, limitations, and caveats that apply to the Cisco Catalyst 9500 Series Switches and Cisco Catalyst 9500 Series Switches - High Performance models. Throughout this release note document, any such differences are expressly called out. If they are not, the information applies to all models in the series.

Boot Integrity Visibility

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


See System Management → Boot Integrity Visibility .


(Network Essentials and Network Advantage)

Disabling MAC Address Learning on VLAN

The MAC address table contains address information that the switch uses to forward traffic between ports. All MAC addresses in the address table are associated with one or more ports.

By default, MAC address learning is enabled on all interfaces and VLANs on the router. You can control MAC address learning on VLAN to manage the available MAC address table space by controlling which VLANs can learn the MAC addresses. Before you disable MAC address learning, be sure that you are familiar with the network topology and the router system configuration. Disabling MAC address learning on aVLAN could cause flooding in the network.


See System Management → Administering the Device .

See Network Management → Configuring ERSPAN .


(DNA Advantage)

Fast Unidirectional Link Detection (UDLD)

Enables subsecond UDLD. The UDLD protocol helps monitor a physical connection (such as monitoring wrong cabling) to detect unidirectional links to avoid spanning-tree topology loops or silent drop traffic.


See Layer 2 → Configuring UniDirectional Link Detection .


(Network Essentials and Network Advantage)

IPv6 Support for SGT and SGACL

Facilitates dynamic learning of mappings between IP addresses and Security Group Tags (SGTs) for IPv6 addresses. The SGT is then used to derive the Security Group Access Control List (SGACL).


See Cisco TrustSec → IPv6 Support for SGT and SGACL .


(Network Advantage)

Multiprotocol Label Switching

  • Ethernet over MPLS (EoMPLS)

  • Virtual Private LAN Services (VPLS)

  • external BGP (eBGP) and internal BGP (iBGP)

The following MPLS features are introduced in this release:

  • EoMPLS—One of the Any Transport over MPLS (AToM) transport types. EoMPLS provides a tunneling mechanism for Ethernet traffic through an MPLS-enabled Layer 3 core. It encapsulates Ethernet protocol data units (PDUs) inside MPLS packets and uses label stacking to forward them across the MPLS network.

  • VPLS—A class of VPN that supports the connection of multiple sites in a single bridged domain over a managed IP/MPLS network. VPLS uses the provider core to join multiple attachment circuits together, to simulate a virtual bridge that connects the multiple attachment circuits together.

  • eBGP and iBGP—Enables you to configure multipath load balancing with both eBGP and iBGP paths in Border Gateway Protocol (BGP) networks that are configured to use MPLS VPNs. The feature provides improved load balancing deployment and service offering capabilities and is useful for multi-homed autonomous systems and Provider Edge (PE) routers that import both eBGP and iBGP paths from multihomed and stub networks.


See Multiprotocol Label Switching (MPLS) .


(Network Advantage)

SGT Name Export in NetFlow

Allows Flexible NetFlow to export Cisco TrustSec environmental data tables that map SGTs to Security Group Names.


See Cisco TrustSec → Flexible NetFlow Export of Cisco TrustSec Fields .


(DNA Essentials and DNA Advantage)

Top-N Reports

Enable you to collect and analyze data for each physical port on a switch. When Top-N reports start, they obtain statistics from the appropriate hardware counters and then go into sleep mode for a user-specified interval. When the interval ends, the reports obtain current statistics from the same hardware counters, compare current statistics with the earlier statistics, and store the difference.


See Network Management → Top-N Reports .

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. For information about CLI help, see Understanding the Help System. Such hidden commands are only meant to assist Cisco TAC in advanced troubleshooting and are therefore not documented.

Starting with Cisco IOS XE Fuji 16.8.1a, 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.

Upgrading the Switch Software

This section covers the various aspects of upgrading or downgrading the device software.


Note

You cannot use the Web UI to install, upgrade, or downgrade device software.

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.

Automatic Boot Loader Upgrade

When you upgrade from the existing release on your switch to a later or newer release for the first time, the boot loader may be automatically upgraded, based on the hardware version of the switch. If the boot loader is automatically upgraded, it will take effect on the next reload. If you go back to the older release after this, the boot loader is not downgraded. The updated boot loader supports all previous releases.

For subsequent Cisco IOS XE Everest 16.x.x, or Cisco IOS XE Fuji 16.x.x releases, if there is a new bootloader in that release, it may be automatically upgraded based on the hardware version of the switch when you boot up your switch with the new image for the first time.


Caution

Do not power cycle your switch during the upgrade.

Scenario

Automatic Boot Loader Response

If you boot Cisco IOS XE Fuji 16.9.1 or Cisco IOS XE Fuji 16.9.2 or Cisco IOS XE Fuji 16.9.3 or Cisco IOS XE Fuji 16.9.4 or Cisco IOS XE Fuji 16.9.5 or Cisco IOS XE Fuji 16.9.6 or Cisco IOS XE Fuji 16.9.7 or Cisco IOS XE Fuji 16.9.8for the first time.

On Cisco Catalyst 9500 Series Switches, the boot loader may be upgraded to version 16.9.1r [FC3]. For example:
ROM: IOS-XE ROMMON
BOOTLDR: System Bootstrap, Version 16.9.1r [FC3], RELEASE SOFTWARE (P)
On Cisco Catalyst 9500 Series Switches - High Performance, the boot loader may be upgraded to version 16.9.1r [FC3]. For example:
ROM: IOS-XE ROMMON
BOOTLDR: System Bootstrap, Version 16.9.1r [FC3], RELEASE SOFTWARE (P)

If the automatic boot loader upgrade occurs, while booting Cisco IOS XE Fuji 16.9.1 or Cisco IOS XE Fuji 16.9.2 or Cisco IOS XE Fuji 16.9.3 or Cisco IOS XE Fuji 16.9.4 or Cisco IOS XE Fuji 16.9.5 or Cisco IOS XE Fuji 16.9.6, you will see the following on the console:

Step 6

Reload

This step is required only if you install the software image to flash by using the request platform software package install command.

  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 Fuji 16.9.1 image on the device:
    Switch# show version

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 9500 Series Switches and Cisco Catalyst 9500 Series Switches - High Performance 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 3. Permitted Combinations

    DNA Essentials

    DNA Advantage

    Network Essentials

    Yes

    No

    Network Advantage

    Yes7

    Yes

    7 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.

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.

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

Limitations and Restrictions

With Cisco Catalyst 9500 Series Switches and Cisco Catalyst 9500 Series Switches - High Performance—If a feature is not supported on a switch model, you do not have to factor in any limitations or restrictons that may be listed here. If limitations or restrictions are listed for a feature that is supported, check if model numbers are specified, to know if they apply. If model numbers are not specified, the limitations or restrictons apply to all models in the series.

  • Cisco StackWise Virtual:

    • You cannot configure StackWise Virtual links on the uplink (network) modules (C9500-NM-8X and C9500-NM-2Q).

    • On Cisco Catalyst 9500 Series Switches, you cannot use 4X10G breakout cables or the Cisco QSFP to SFP or SFP+ Adapter (QSA) module when Cisco StackWise Virtual is configured on the switch.

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

  • 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.

  • 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 switched virtual interfaces (SVIs), port-channel, 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:

    • Use the MODE button to switch-off the beacon LED.

    • All port LED behavior is undefined until interfaces are fully initialized.

    • The following limitations apply to Cisco QSA Module (CVR-QSFP-SFP10G) when Cisco 1000Base-T Copper SFP (GLC-T) or Cisco 1G Fiber SFP Module for Multimode Fiber are plugged into the QSA module:

      • 1G Fiber modules over QSA do not support autonegotiation. Auto-negotiation should be disabled on the far-end devices.

      • Although visible in the CLI, the command [no] speed nonegotiate is not supported with 1G Fiber modules over QSA.

      • Only GLC-T over QSA supports auto-negotiation.

      • GLC-T supports only port speed of 1000 Mb/s over QSA. Port speeds of 10/100-Mb/s are not supported due to hardware limitation.

    • 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.

    • Autonegotiation is not supported on HundredGigabitEthernet1/0/49 to HundredGigabitEthernet1/0/52 uplink ports of the C9500-48Y4C models, and HundredGigabitEthernet1/0/25 to HundredGigabitEthernet1/0/28 uplink ports of the C9500-24Y4C models. Disable autonegotiation on the peer device if you are using QSFP-H40G-CUxx and QSFP-H40G-ACUxx cables.

    • For QSFP-H100G-CUxx cables, the C9500-48Y4C and C9500-24Y4C models support the cables only if both sides of the connection are either C9500-48Y4C or C9500-24Y4C.

  • 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)

    • 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.

  • 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.

  • Wired Application Visibility and Control limitations:

    • NBAR2 (QoS and Protocol-discovery) configuration is allowed only on wired physical ports. It is not supported on virtual interfaces, for example, VLAN, port channel nor other logical interfaces.

    • NBAR2 based match criteria ‘match protocol’ is allowed only with marking or policing actions. NBAR2 match criteria will not be allowed in a policy that has queuing features configured.

    • ‘Match Protocol’: up to 256 concurrent different protocols in all policies.

    • NBAR2 and Legacy NetFlow cannot be configured together at the same time on the same interface. However, NBAR2 and wired AVC Flexible NetFlow can be configured together on the same interface.

    • Only IPv4 unicast (TCP/UDP) is supported.

    • AVC is not supported on management port (Gig 0/0)

    • NBAR2 attachment should be done only on physical access ports. Uplink can be attached as long as it is a single uplink and is not part of a port channel.

    • Performance—Each switch member is able to handle 500 connections per second (CPS) at less than 50% CPU utilization. Above this rate, AVC service is not guaranteed.

    • Scale—Able to handle up to 5000 bi-directional flows per 24 access ports and 10000 bi-directional flows per 48 access ports.

  • 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.
