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

- Pass 1: Overwrites all addressable locations with binary zeroes.

- Pass 2: Overwrites all addressable locations with binary ones.

- Pass 3: Overwrites all addressable locations with a random bit pattern.

See System Management → Performing Factory Reset.

(Network Essentials and Network Advantage)

IPv6: HTTP SGACL enforcement with IPv6 Policy Server

Supports 8 IPv4 and 8 IPv6 addresses per server for SGACL and Environment Data Download over REST.

See Cisco TrustSec → SGACL and Environment Data Download over REST.

(Network Advantage)

Loop Detection Guard

Provides a way of detecting network loops. The feature can be used in situations where there may be unmanaged switches in a network that do not understand Spanning Tree Protocol (STP) or where STP is not configured on the network.

You can take one of these actions when a loop is detected: error-disable either the source port or the destination port, or have the system display a syslog message (and not disable a port).

See Layer 2 → Configuring Loop Detection Guard.

(Network Essentials and Network Advantage)

Multiple Administrative VLANS in Resilient Ethernet Protocol (REP)

You can now configure multiple administrative VLANs to manage an REP domain that has multiple REP segments that are mutually exclusive.

Configure the additional administrative VLANs by entering the rep admin vlan command in global configuration mode.

See Layer 2 → Configuring Resilient Ethernet Protocol.

(Network Essentials and Network Advantage)

Programmability

- TLDP On-Change Notifications

- YANG Data Models

The following programmability features are introduced in this release:

- TLDP On-Change Notifications: Notifies users when Targeted Label Distribution Protocol (TLDP) sessions come up or go down and when TLDP is configured or disabled. TLDP must be enabled for the notifications to work.

(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/1721.

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.

(Network Essentials and Network Advantage)

See Programmability.

SCP Performance Improvements

Secure Shell (SSH) bulk data transfer mode can now be used to enhance the throughput performance of Secure Copy Protocol (SCP) operating in the capacity of a client or server. You can enable this by using the ip ssh bulk-mode global configuration command.

See System Management → Secure Copy.

(Network Essentials and Network Advantage)

Session Limit - To prevent MAC address flooding DOS attack

Enables you to configure an access session limit profile, which will allow you to limit the number of voice and data hosts connecting to a port.

See Security → Configuring IEEE 802.1x Port-Based Authentication.

(Network Essentials and Network Advantage)

VLAN Load Balancing for FlexLink+

Introduces support for VLAN load balancing on a FlexLink+ pair (along with providing the redundancy). Both ports of a FlexLink+ pair can now simultaneously forward traffic in mutually exclusive VLANs. If one of the ports fail, the other active port forwards all traffic. When the failed port is available again, it resumes forwarding of traffic in the preferred VLANs.

See Layer 2 → Configuring Flexlink+.

(Network Essentials and Network Advantage)

VLAN Translation Scale Increase: One-to-One Mapping

You can now configure a total of 3000 one-to-one mappings on the device - with each ASIC supporting up to 1000 mappings.

See Layer 2/3 → show platform software fed (ifm mappings).

(Network Advantage)

Hierarchical VPLS with MPLS access

Reduces signaling overhead and packet replication between devices when compared to configuring VPLS.

See Multiprotocol Label Switching (MPLS) → Configuring Hierarchical VPLS with MPLS Access.

(Network Essentials and Network Advantage)

VPLS: Routed Pseudowire IRB for IPv4 Unicast

Enables a switch interface to route traffic instead of using a router.

See Multiprotocol Label Switching (MPLS) → Configuring VPLS: Routed Pseudowire IRB for IPv4 Unicast.

(Network Essentials and Network Advantage)

VPN ID in NetFlow

Supports Virtual Private Network Identifier (VPN-ID) configuration in Flexible NetFlow. A VPN-ID is global and unique. It is used to identify a VPN across autonomous systems (ASes).

See Network Management → Configuring Flexible NetFlow.

(Network Essentials and Network Advantage)

VRF Aware NAT

VRF awareness enables NAT to carry out address translation by taking the VRF of the private networks into consideration. This feature allows private networks to be placed in different VRFs.

See IP Addressing Services → Configuring Network Address Translation.

(Network Essentials and Network Advantage)

VRF Support for TCL Socket

The Tool Command Language (TCL) socket feature supports Virtual Routing and Forwarding (VRF).

See Network Management Commands.

(Network Essentials and Network Advantage)

New on the Web UI

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. That is, entering a question mark (?) at the system prompt did not display the list of available commands. These commands were only meant to assist Cisco TAC in advanced troubleshooting and were not documented either.

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. Enter enter a question mark (?) at the system prompt to display 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 a hidden 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.

Default Behaviour

Beginning from Cisco IOS XE Gibraltar 16.12.5 and later, do not fragment bit (DF bit) in the IP packet is always set to 0 for all outgoing RADIUS packets (packets that originate from the device towards the RADIUS server).

ROMMON and CPLD Versions

This topic list the ROMMON and CPLD versions for Cisco Catalyst 9400 Series Switches.

ROMMON

ROMMON, also known as the boot loader, is firmware that runs when the device is powered up or reset. It initializes the processor hardware and boots the operating system software (Cisco IOS XE software image). The ROMMON is stored on the following Serial Peripheral Interface (SPI) flash devices on your switch:

- Primary: The ROMMON stored here is the one the system boots every time the device is powered-on or reset.

- Golden: The ROMMON stored here is a backup copy. If the one in the primary is corrupted, the system automatically boots the ROMMON in the golden SPI flash device.

ROMMON upgrades may be required to resolve firmware defects, or to support new features, but there may not be new versions with every release. A Cisco IOS XE release is also compatible with a ROMMON version lower or higher than what is specified in this table. For more information, see "Upgrading the ROMMON" section.

Complex Programmable Logic Device (CPLD)

CPLD refers to hardware-programmable firmware. We recommend that you perform CPLD upgrade to resolve firmware defects or to support new features. There may not be new CPLD versions with every release.

If your device is running CPLD version 0x171017, you must upgrade to a later version. Every IOS XE version has a specific CPLD version bundled with it as shown in the table below. If your device is running CPLD version lower than the version bundled with the IOS XE image, we recommend you upgrade the CPLD. IOS XE does not allow CPLD downgrade. For information on how to perform CPLD upgrade, refer Upgrading the Complex Programmable Logic Device Version.

This table provides ROMMON and CPLD version information for the Cisco Catalyst 9400 Series Supervisor Modules. For ROMMON and CPLD version information of Cisco IOS XE 16.x.x releases, refer to the corresponding Cisco IOS XE 16.x.x release notes of the respective platform.

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

- Software Images

- Upgrading the ROMMON

- Software Installation Commands

- Upgrading in Install Mode

- Downgrading in Install Mode

- Upgrading the Complex Programmable Logic Device Version

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.

Upgrading the ROMMON

To know the ROMMON or bootloader version that applies to every major and maintenance release, see ROMMON and CPLD Versions.

You can upgrade the ROMMON before, or, after upgrading the software version. If a new ROMMON version is available for the software version you are upgrading to, proceed as follows:

- Upgrading the ROMMON in the primary SPI flash device

This ROMMON is upgraded automatically. When you upgrade from an existing release on your switch to a later or newer release for the first time, and there is a new ROMMON version in the new release, the system automatically upgrades the ROMMON in the primary SPI flash device, based on the hardware version of the switch when you boot up your switch with the new image for the first time.

- Upgrading the ROMMON in the golden SPI flash device

You must manually upgrade this ROMMON. Enter the upgrade rom-monitor capsule golden switch command in privileged EXEC mode.

Note

In case of a Cisco StackWise Virtual setup, upgrade the active and standby switch.

In case of a High Availability set up, upgrade the active and standby switch.

After the ROMMON is upgraded, it will take effect on the next reload. If you go back to an older release after this, the ROMMON is not downgraded. The updated ROMMON supports all previous releases.

Software Installation Commands

Summary of Software Installation Commands

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

install add file filename [ activate commit]

To separately install, activate, commit, cancel, or remove the installation file: install ?

add file tftp: filename

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

activate [ auto-abort-timer]

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

commit

Makes changes persistent over reloads.

rollback to committed

Rolls back the update to the last committed version.

abort

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

Caution

You must comply with these cautionary guidelines during an upgrade:

- Do not power cycle the 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.

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

Step 5

Verify installation

show version

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

The following sample output of the show version command displays the Cisco IOS XE Amsterdam 17.2.1 image on the device:

<output truncated>

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 Amsterdam 17.2.1

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 Amsterdam 17.1.1 or earlier releases.

The sample output in this section shows downgrade from Cisco IOS XE Amsterdam 17.2.1 to Cisco IOS XE Amsterdam 17.1.1, 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

You can trigger a CPLD version upgrade after upgrading the software image. During CPLD upgrade, the supervisor module automatically power cycles which may cause a temporary loss of uplink connectivity. This completes the CPLD upgrade process for the supervisor module. Auto-upgrade of CPLD is not supported, and so you must manually perform CPLD upgrade.

- Upgrading the CPLD Version: High Availability Setup

- Upgrading the CPLD Version: Cisco StackWise Virtual Setup

- Upgrading the CPLD Version: Single Supervisor Module Setup

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: switch standby [r0 | r1]

Use r0 if the targeted Supervisor is on the lower slot of the chassis, and r1 if the targeted Supervisor is on the upper slot of the chassis.

Note

For the upgrade hw-programmable cpld filename bootflash command, configure with the switch keyword only. The other available keywords are not applicable when upgrading with Cisco StackWise Virtual.

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.

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.

- M.2 SATA SSD drive: 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.

- 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.

- 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

- 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.

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

- Switch Web UI allows configuration of data VLANs only and not voice VLANs. If you remove a voice VLAN configured to an interface using the Web UI, then all data VLANs associated with the interface are also removed by default.
