(Network Essentials and Network Advantage)

Border Gateway Protocol (BGP) Ethernet VPN (EVPN) Route Target (RT) Autonomous System Number (ASN) Rewrite

Introduces support for the rewrite-evpn-rt-asn command in address-family configuration mode. This command enables the rewrite of the ASN portion of the EVPN route target that originates from the current autonomous system, with the ASN of the target eBGP EVPN peer.

See IP Routing Commands → rewrite-evpn-rt-asn.

(Network Advantage)

Bidirectional Protocol Independent Multicast (PIM)

Introduces support for bidirectional PIM. This feature is an extension of the PIM suite of protocols that implements shared sparse trees with bidirectional data flow. In contrast to PIM-sparse mode, bidirectional PIM avoids keeping source-specific state in a router and allows trees to scale to an arbitrary number of sources.

See IP Multicast Routing → Configuring Protocol Independent Multicast (PIM).

(Network Advantage)

Cisco StackWise Virtual

Introduces support for a network system virtualization technology that pairs two switches into one virtual switch, to simplify operational efficiency with a single control and management plane.

See High Availability → Configuring Cisco StackWise Virtual.

(Network Advantage)

Accessing Hidden Commands

This section provides information about hidden commands in Cisco IOS XE and the security measures in place, when they are accessed. Hidden commands are 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.

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 Versions

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.

The following table provides ROMMON version information for the Cisco Catalyst 9600 Series Supervisor Modules. For ROMMON version information of Cisco IOS XE 17.x.x releases, refer to the corresponding Cisco IOS XE 17.x.x release notes of the respective platform.

Automatic Boot Loader Upgrade

Caution

You must comply with these cautionary guidelines during an upgrade:

- Do not power cycle your switch.

- Do not disconnect power or remove the supervisor module.

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

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

Field-Programmable Gate Array Version Upgrade

A field-programmable gate array (FPGA) is a type of programmable memory device that exists on Cisco switches. They are re-configurable logic circuits that enable the creation of specific and dedicated functions.

The FPGA upgrade process is part of the software image upgrade. The FPGA version does not downgrade when you downgrade the software image.

After completing the upgrade procedure, you can verify the FPGA version against the value in the table below. Enter the show firmware version all command in IOS mode or version -v command in ROMMON mode.

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 ...

To ...

Cisco IOS XE Gibraltar 16.12.x

Cisco IOS XE Gibraltar 16.11.x or an earlier release.

The sample output in this section shows downgrade from Cisco IOS XE Gibraltar 16.12.1 to Cisco IOS XE Gibraltar 16.11.1, using install commands.

Important

New switch models 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.

Licensing

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

- License Levels

- License Types

- License Levels - Usage Guidelines

- Cisco Smart Licensing

License Levels

The software features available on Cisco Catalyst 9600 Series Switches fall under these base or add-on license levels.

Base Licenses

- Network Advantage

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 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.

- 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-Advantage) are ordered and fulfilled only with a permanent license type.

- Add-on licenses (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.

- 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.

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

Deploying Smart Licensing

The following provides a process overview of a day 0 to day N deployment directly initiated from a device. 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

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

- Auto negotiation: The SFP+ interface (TenGigabitEthernet0/1) on the Ethernet management port with a 1G transceiver does not support auto negotiation.

- 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.

- Hardware Limitations — Optics:

- Copper cables are not supported with 25GE, 40GE, and 100GE configurations

- Installation restriction for C9600-LC-24C linecard with CVR-QSFP-SFP10G adapter —This adapter must not be installed on an even numbered port where the corresponding odd numbered port is configured as 40GE port. For example, if port 1 is configured as 40GE, CVR-QSFP-SFP10G must not be installed in port 2.

Installation restriction for C9600-LC-24C linecard with CVR-QSFP-SFP10G adapter — If you insert a 40-Gigabit Ethernet Transceiver Module to odd numbered port, the corresponding even numbered port does not work with CVR-QSFP-SFP10G adapter.

- Hardware Limitations — Power Supply Modules:

- Input voltage for AC power supply modules—All AC-input power supply modules in the chassis must have the same AC-input voltage level.

- Using power supply modules of different types—When mixing AC-input and DC-input power supplies, the AC-input voltage level must be 220 VAC.

- Convergence: During SSO, a higher convergence time is observed while removing the active supervisor module installed in slot 3 of a C9606R chassis.

- In-Service Software Upgrade (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.

- QoS restrictions

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

- Policing and marking policy on sub interfaces is supported.

- Marking policy on switched virtual interfaces (SVI) is supported.

- 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.

- 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.

- 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.
