Release Notes for Cisco Catalyst 9400 Series Switches, Cisco IOS XE Gibraltar 16.11.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 Unified Access Data Plane (UADP) 2.0 and UADP 3.0. 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

Feature Name

Description, Documentation Link and License Level Information

BGP PE-CE support for MPLS Layer 3 VPNs

Supports BGP as a routing protocol between the provider edge (PE) device and the customer edge (CE) device.

See Configuring MPLS Layer 3 VPN.

(Network Advantage)

Cisco StackWise Virtual

  • Support on C9400-SUP-1XL-Y and C9410R

  • Recovery Reload

The Cisco StackWise Virtual feature includes the following enhancements in this release:

  • The feature is now supported on the following hardware:

    • Cisco Catalyst 9400 Series Supervisor 1XL 25G Module (C9400-SUP-1XL-Y)

    • Cisco Catalyst 9400 Series 10 Slot Chassis (C9410R)

  • Recovery Reload—Introduces a new default reload action after recovering from a link failure and the option to disable this default.

    Starting with this release, after recovering from a StackWise Virtual link failure, the failed active switch automatically performs a reload action and restores itself as a standby switch. This is the new default behaviour in the event of a link failure.

    You can also configure the dual-active recovery-reload-disable command in the stackwise-virtual configuration mode, to retain the switch in recovery mode and prevent the switch from reloading automatically.

See High Availability → Configuring Cisco StackWise Virtual.

(Network Advantage)

Consent Token for Shell Access

Authenticates a network administrator’s request to access the system shell.

When debugging software issues, a Cisco TAC engineer may have to work with a network administrator to collect debug information or perform live debugging on a production system. This feature provides the network administrator with privileged, restricted, and secure access to the system shell with mutual consent from the network administrator and Cisco TAC.

See System Management → Consent Token.

(Network Essentials and Network Advantage)

  • IPv6: OSPF Update Packet-Pacing Configurable Timers

See IP Routing.

(Network Essentials and Network Advantage)

IPv6: OSPF Limit on Number of Redistributed Routes

Enables you to configure a maximum number of prefixes (routes) that can be redistributed into OSPFv3 from other protocols or other OSPFv3 processes. Such a limit helps prevent the device from being flooded by too many redistributed routes.

See IP Routing → Configuring OSPFv3 Limit on Number of Redistributed Routes.

(Network Essentials and Network Advantage)

IPv6: RFC 5453 Reserved IPv6 Interface Identifiers

An autoconfigured IPv6 address will contain interface identifiers that are not part of the reserved range of interface identifiers specified in RFC 5453.

See IP Multicast Routing → IP Multicast Routing Technology Overview.

(Network Essentials and Network Advantage)

IPv6 Downloadable ACL (DACL)

Applies per-port IPv6 access-layer restrictions based on Identity Services Engine (ISE) profiles.

See Security → IPv6 ACLs.

(Network Essentials and Network Advantage)

IPv6 Support for Virtual Extensible LAN (VXLAN) Border Gateway Protocol (BGP) Ethernet VPN (EVPN) in Routed Mode

Introduces IPv6 support for the VXLAN BGP EVPN operation in routed mode.

A VXLAN is a network overlay that allows layer 2 segments to be stretched across an IP core. All the benefits of Layer 3 topologies are thereby available with VXLAN. The overlay protocol is VXLAN and BGP uses EVPN as the address family for communicating end host MAC and IP addresses. VXLAN BGP EVPN operates in bridged mode when the hosts are in the same subnet, and in routed mode when the hosts are in different subnets.

See Layer 2 → Configuring VXLAN BGP EVPN.

(Network Advantage)

Multiprotocol Label Switching (MPLS)

  • MPLS VPN-Inter-AS Option B

  • MPLS VPN-Inter-AS-IPv4 BGP Label Distribution

  • MPLS over GRE

  • MPLS VPN eBGP Multipath Support for Inter-AS VPNs

  • MPLS VPN-Inter-AS Option B—Allows an MPLS Virtual Private Network (VPN) service provider to interconnect different autonomous systems to provide VPN services. In an Inter-AS Option B network, autonomous system boundary router (ASBR) peers are connected by one or more interfaces that are enabled to receive MPLS traffic.

  • MPLS VPN-Inter-AS-IPv4 BGP Label Distribution—Enables you to set up a VPN service provider network so that ASBRs exchange IPv4 routes with MPLS labels of the provider edge (PE) routers.

  • MPLS over GRE—Provides a mechanism for tunneling MPLS packets over non-MPLS networks by creating a generic routing encapsulation (GRE) tunnel. The MPLS packets are encapsulated within the GRE tunnel packets, and the encapsulated packets traverse the non-MPLS network through the GRE tunnel. When GRE tunnel packets are received at the other side of the non-MPLS network, the GRE tunnel packet header is removed and the inner MPLS packet is forwarded to its final destination.

  • MPLS VPN eBGP Multipath Support for Inter-AS VPNs—Enables you to configure external Border Gateway Protocol (eBGP) multipath with IPv4 labels. It allows load balancing of VPN traffic when you use VPNv4 peering for Inter-AS VPNs.

    Without this feature, the MPLS forwarding table contains the labels only for the BGP best path even though the routing table has more than one path for the prefix.

See Multiprotocol Label Switching.

(Network Advantage)

Option to Disable System Thermal Shutdown

Provides an option to manually bypass the system thermal shutdown process, by preventing the triggering of the supervisor module's action to turn off the power supplies of the chassis even when temperatures exceed the critical and shutdown thresholds.

See System Management → Environmental Monitoring and Power Management.

(Network Essentials and Network Advantage)

Password Configuration: Secure Password Migration

Introduces support for migration of type 0 and type 7 usernames and passwords to type 6.

Password protection restricts access to a network or network device. Encrypting passwords provides an additional layer of security, particularly for passwords that cross the network or are stored on a TFTP server. Starting with this release, the switch supports automatic conversion of usernames and passwords with type 0 and type 7 encryption, to type 6 encryption. Type-6 is a strong, reversible 128-bit Advanced Encryption Standard (AES) password encryption. To start using type-6 encryption, you must enable the AES password encryption feature and configure a primary encryption key, which is used to encrypt and decrypt passwords.

See Security → Controlling Switch Access with Passwords and Privilege Levels.

(Network Essentials and Network Advantage)

Programmability

  • Kill Telemetry Subscription

  • NETCONF and RESTCONF Service Level Access Control Lists

  • YANG Data Models

The following programmability features are introduced in this release:

  • Kill Telemetry Subscription—Provides the ability to delete a dynamic model driven telemetry subscription using either:

    • The clear telemetry ietf subscription Cisco IOS command, or

    • The <kill-subscription> RPC

  • NETCONF and RESTCONF Service Level Access Control Lists (ACLs)—Enables you to configure an IPv4 or IPv6 ACL for NETCONF and RESTCONF sessions.

    Clients that do not conform to the configured ACL are not allowed to access the NETCONF or RESTCONF subsystems. When service-level ACLs are configured, NETCONF and RESTCONF connection requests are filtered based on the source IP address.

  • 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/16111.

    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.

(Network Essentials and Network Advantage)

Radioactive Tracing

The request platform software trace filter-binary and the show platform software trace filter-binary commands were introduced in this release. These commands can be used to collate and sort all the archived logs present in the trace logs subdirectory and to filter the most recent trace information from the temporary directory for a specific module, respectively.

See System Management Commands.

(Network Advantage)

Smart Licensing: System Messages for an Evaluation License

Evaluation licenses that are not registered will still expire after the 90-day period, but warning system messages about an evaluation license expiry will now be generated only 275 days after this 90-day window.

See License Levels - Usage Guidelines.

(A license level does not apply)

Supported Spanning-Tree Instances

In per-VLAN spanning-tree plus (PVST+), Rapid PVST+ mode, the device now supports up to 256 spanning-tree instances.

See Layer 2.

(Network Essentials and Network Advantage)

Time Domain Reflectometer (TDR)

Determines if a cable is OPEN or SHORT when it is at fault. This involves running a TDR test, which detects a cable fault by sending a signal through the cable and reading the signal that is reflected back.

To run the test, enter the test cable-diagnostics tdr command in privileged EXEC mode; to display test results, enter the show cable-diagnostics tdr command in privileged EXEC mode.

See Interface and Hardware Components → Checking Port Status and Connectivity.

(Network Essentials and Network Advantage)

New on the Web UI

  • Application Visibility and Control (AVC)

  • Switching Database Manager (SDM) templates

  • Cisco TrustSec

Use the WebUI to:

  • Configure and monitor AVC—Enables you to configure application-level classification, monitoring, and traffic control. It helps with improved network capacity management, faster troubleshooting, and lower operating costs. Also, Network-Based Application Recognition (NBAR) supports the use of custom protocols to identify customer-specific applications.

  • Apply SDM templates—Helps configure system resources to optimize support for specific features, depending on how your device is used in the network.

  • Configure and monitor Cisco TrustSec—Helps build secure networks by establishing domains of trusted network devices. Each device in the domain is authenticated by its peers. Communication on the links between devices in the domain is secured with a combination of encryption, message integrity check, and data-path replay protection mechanisms.

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 Interface → Understanding 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.

Cancels 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.

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 16.11.x

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 16.11.x using install commands.

Procedure

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 16.11.x 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 16.11.x

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 16.10.x or earlier releases.

The sample output in this section shows downgrade from Cisco IOS XE Gibraltar 16.11.x 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.

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 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

For information about feature scaling guidelines, see these datasheets for Cisco Catalyst 9400 Series Switches:

https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9400-series-switches/nb-06-cat9400-ser-data-sheet-cte-en.html

https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9400-series-switches/nb-06-cat9600-series-line-data-sheet-cte-en.html

https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9400-series-switches/nb-06-cat9400-ser-sup-eng-data-sheet-cte-en.html

Limitations and Restrictions

  • Cisco StackWise Virtual—A special, additional, C9400-SUP-UPG-LIC= license is required to configure the feature on the Cisco Catalyst 9400 Series Supervisor 1 Module (C9400-SUP-1).

  • 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: 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 16.11.x is not supported. This applies to both a single and dual supervisor module setup.

  • 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.

    • Stack Queuing and Scheduling (SQS) drops CPU bound packets exceeding 1.4 Gbps.

  • 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.
    Switch# show redundancy

  • 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.

  • 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

  • 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.

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

  • Secure Password Migration—Type 6 encrypted password is supported from Cisco IOS XE Gibraltar 16.10.1 and later releases. Autoconversion to password type 6 is supported from Cisco IOS XE Gibraltar 16.11.1 and later releases.

    If the startup configuration has a type 6 password and you downgrade to a version in which type 6 password is not supported, you can/may be locked out of the device.

  • The File System Check (fsck) utility is not supported in install mode.
