- 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)

VRFs

The C9200-24PB and C9200-48PB models of the Cisco Catalyst 9200 Series Switches support 32 VRFs.

Accessing Hidden Commands

This section provides information about hidden commands in Cisco IOS XE and the security measures that are in place, when they are accessed. These commands are only meant to assist Cisco TAC in advanced troubleshooting and are not documented.

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).

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.

Caution

Do not power cycle your switch during the upgrade.

Software Installation Commands

Step 5

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

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 Amsterdam 17.2.1 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 through 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 Amsterdam 17.2.1

Cisco IOS XE Amsterdam 17.1.x 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 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 9200 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:

Permitted Combinations

DNA Essentials

DNA Advantage

Network Essentials

Yes

No

Network Advantage

Yes[1]

Yes

[1] 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

- 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

Scaling Guidelines

For information about feature scaling guidelines, see the Cisco Catalyst 9200 Series Switches datasheet at:

https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9200-series-switches/nb-06-cat9200-ser-data-sheet-cte-en.html

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.

- Hardware limitations

- Management Port—You cannot modify the configured port speed, duplex mode and flow control and disable auto-negotiation on the Ethernet Management port (GigabitEthernet0/0). Port speed and duplex mode can only be changed from a peer port.

- Network Module — When the C9200-NM-4X network module is plugged into the C9200 SKUs of the Cisco Catalyst 9200 Series Switches, the downlink interface remains in down state until the network module is recognized by the switch. The time taken for the switch to recognize the network module is longer in comparison to the time taken by the switch to recognize other interconnected devices.

- If the 1-meter and 1.5-meter 10-GBase-CX1 cables, which are connected on the 10-G ports of the Catalyst 9200L switches, are connected to the 10-G peer ports of the Catalyst 9200L or Catalyst 9200 switches, the peer device might go into the error-disabled state because of link flapping if the local device is restarted. As a workaround, run the shut and no shut commands on the error-disabled peer interfaces.

- 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.

- Stacking

- Stacking is supported on Cisco Catalyst 9200 Series Switches. A switch stack supports up to eight stack members. However, you cannot stack C9200 SKUs with C9200L SKUs

The supported stacking bandwidth on C9200L SKUs is up to 80Gbps; on C9200 SKUs, this is up to 160Gbps.

- The C9200-24PB and C9200-48PB switch models can be stacked only with each other and not with other models of the Cisco Catalyst 9200 Series Switches.

- Auto upgrade for a new member switch is supported only in the install mode.

- 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.

- Upgrading the software image from Cisco IOS XE Gibraltar 16.12.x to any of the later releases can result in a persistent database operation failure and after which the persistent database cannot be restored.

To avoid the persistent database operation failure, use the dir bootflash:.dbpersist command to list all DB persist files and then use delete bootflash:/.dbpersist/folder_name/file_name and bootflash:/.dbpersist/folder_name/file_name.meta commands to delete individual database and meta files from each persistent database folder.

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

- The DiagMemoryTest GOLD test is not supported on the Catalyst 9200 Series Switches.
