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.

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 any prior Cisco IOS XE 3.x.xE release to a Cisco IOS XE Denali 16.x.x, or Cisco IOS XE Everest 16.x.x, or Cisco IOS XE Fuji 16.x.x 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 a Cisco IOS XE Release 3.x.xE, your boot loader will not be downgraded. The updated boot loader supports all previous releases.

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

Caution

Do not power cycle your switch during the upgrade.

Automatic Microcode Upgrade

During a Cisco IOS image upgrade or downgrade on a PoE or UPoE switch, microcode is upgraded to reflect applicable feature enhancements and bug fixes. A microcode upgrade occurs only during an image upgrade or downgrade, on PoE or UPoE switches. It does not occur during switch reloads or on non-PoE switches.

Depending on the release you are upgrading from, microcode upgrade can occur during the install operation or during bootup:

If the release you are upgrading from does not support microcode updates during the course of installation, microcode is updated during boot up, and an additional 4 minutes (approximately) are required to complete the microcode upgrade, in addition to the normal reload time. Data traffic is not forwarded when microcode is upgraded during bootup.
When using install commands to upgrade, microcode is upgraded during the install operation, and no additional time is required during bootup. Here microcode is updated before the reload that occurs as part of the image upgrade process. Data traffic continues to be forwarded during the upgrade.

Do not restart the switch during the upgrade or downgrade process.

The following console messages are displayed during microcode upgrade:


MM [1] MCU version 111 sw ver 105

Upgrading from Cisco IOS XE Release 3.x.xE in Bundle Mode

Follow these instructions to upgrade from Cisco IOS XE Release 3.x.xE in bundle mode:

Before you begin

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


When upgrading from ...	Use these commands...	To upgrade to...
Any Cisco IOS XE Release 3.x.xE	Only request platform software commands	Cisco IOS XE Gibraltar 16.x.x or Cisco IOS XE Fuji 16.x.x or Cisco IOS XE Everest 16.x.x or Cisco IOS XE Denali 16.x.x

The sample output shows upgrade from Cisco IOS XE Release 3.7.3E to Cisco IOS XE Gibraltar 16.12.1

Procedure

Step 1

Note

You cannot boot Cisco IOS XE Gibraltar 16.x.x, Cisco IOS XE Fuji 16.x.x, Cisco IOS XE Everest 16.x.x, or Cisco IOS XE Denali 16.x.x via TFTP for the first time with a Cisco IOS XE 3.x.xE boot loader. The Cisco IOS XE 3.x.xE boot loaders have a limitation, which prevents the booting of an image larger than 400MB via the TFTP server. Since Cisco IOS XE Gibraltar 16.x.x, Cisco IOS XE Fuji 16.x.x, Cisco IOS XE Everest 16.x.x, and Cisco IOS XE Denali 16.x.x images are larger than 400MB, you must boot the image via flash.

Upgrading from Cisco IOS XE Denali 16.x.x in Install Mode

Follow these instructions to upgrade from a Cisco IOS XE Denali 16.x.x release to a later release in install mode. In order to perform a software image upgrade, you must be booted into IOS using boot flash:packages.conf .

Before you begin

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


When upgrading from ...	Use these commands...	To upgrade to...
Cisco IOS XE Denali 16.x.x or Cisco IOS XE Everest 16.x.x	Only request platform software commands.	Cisco IOS XE Gibraltar 16.x.x or Cisco IOS XE Fuji 16.x.x or Cisco IOS XE Everest 16.x.x or Cisco IOS XE Denali 16.x.x

The sample output shows upgrade from Cisco IOS XE Denali 16.3.5 to Cisco IOS XE Gibraltar 16.12.1 in install mode.

Procedure

Step 1

Clean Up

request platform software package clean switch all file flash:

Use this command to clean up old installation files; this ensures that you have sufficient space in the flash drive, to expand a new image. Use the switch all option to clean up all switches in your stack.

Step 2

Copy new image to stack

Copy the new image to flash: (If you point to the source image on a TFTP server you can skip this section and go to: Software install image to flash).

copy tftp: flash:

Use this command to copy the image from the tftp server to flash.

Switch# copy tftp://5.28.11.250/cat3k_caa-universalk9.16.12.01.SPA.bin flash:
cat3k_caa-universalk9.16.12.01.SPA.bin

dir flash:

Use this command to confirm that the image has been successfully copied to flash.

Switch# dir flash:*.bin

1562509312 bytes total (731021312 bytes free)
Switch#

Step 3

Software install image to flash

request platform software package install

Use this command to install the target image to flash. Use the switch all option to upgrade all switches in your stack. Use the auto-copy option to copy the .bin image from flash: to all other switches in your stack

We recommend copying the image to a TFTP server or the flash drive of the active switch. If you point to an image on the flash or USB drive of a member switch (instead of the active), you must specify the exact flash or USB drive - otherwise installation fails. For example, if the image is on the flash drive of member switch 3, the corresponding flash drive is flash-3: Switch# request platform software package install switch all file flash-3:cat3k_caa-universalk9.16.12.01.SPA.bin new auto-copy

Note

You must use the new option when you upgrade from Cisco IOS XE Denali 16.1.x, 16.2.x or 16.3.1 to Cisco IOS XE Everest 16.x.x, or Cisco IOS XE Fuji 16.x.x, or Cisco IOS XE Gibraltar 16.x.x , because there are packaging changes in the different 16.x.x releases.

Note

When you execute the command, the following message is displayed. This is expected and does not affect the upgrade. See CSCux82059: Unknown package type 21

Step 4

Reload

reload
Use this command in the privileged EXEC mode to reload the switch.
```
Switch# reload
```

boot flash:

If the switch is configured with auto boot, then the stack automatically boots up with the new image. If not, you can manually boot flash:packages.conf

Note

When you downgrade to a Cisco IOS XE 3.xE image, the boot loader does not automatically downgrade. It remains updated. The new boot loader can support booting both Cisco IOS XE Release 3.x.xE releases as well as Cisco IOS XE Denali 16.x.x, Cisco IOS XE Everest 16.x.x, Cisco IOS XE Fuji 16.x.x, and Cisco IOS XE Gibraltar 16.x.x releases.

Upgrading from Cisco IOS XE Gibraltar 16.12.1 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 through boot flash:packages.conf.

Before you begin

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


When upgrading from ...	Use these commands...	To upgrade to...
Cisco IOS XE Fuji 16.x.x or Cisco IOS XE Gibraltar 16.12.x	Either install commands or request platform software commands	A later Cisco IOS XE 16.x.x release

The sample output in this section displays upgrade from Cisco IOS XE Fuji 16.8.1a to Cisco IOS XE Gibraltar 16.12.1, by using install commands. It also provides information about the corresponding request platform software command, but not the sample output.

Downgrading from Cisco IOS XE Gibraltar 16.12.1 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 ...	Use these commands...	To downgrade to...
Cisco IOS XE Fuji 16.x.x or Cisco IOS XE Gibraltar 16.12.x	Either install commands or request platform software commands	An earlier Cisco IOS XE 16.x.x release

The sample output in this section shows downgrade from Cisco IOS XE Gibraltar 16.12.1 to Cisco IOS XE Fuji 16.9.2, by using install commands. It also provides information about the corresponding request platform software command, but not the sample output.

Important

New switch models that are introduced in a release cannot be downgraded. The release in which a switch model is introduced is the minimum software version for that model. If you add a new switch model to an existing stack, we recommend upgrading all existing switches to the latest release.

Procedure

Licensing

This section provides information about the licensing packages for features available on Cisco Catalyst 3850 Series Switches.

License Levels

The software features available on Cisco Catalyst 3850 Series Switches fall under these base or add-on license levels.

Base Licenses

LAN Base—Provides basic Layer 2+ features, including access control lists (ACLs) and quality of service (QoS), up to 255 VLANs, support for routing protocols (Routing Information Protocol (RIP), Open Shortest Path First (OSPF), Policy-Based Routing (PBR), Protocol Independent Multicast Stub Routing (PIM Stub Routing) with IPv4 and IPv6, and routed access with IPv4 and IPv6 (OSPF — up to 1000 routes, Multicast — up to 1000 routes).
IP Base—Provides Layer 2+ and basic Layer 3 features (enterprise-class intelligent services). These features include access control lists (ACLs), quality of service (QoS), static routing, Enhanced Interior Gateway Routing Protocol (EIGRP) stub routing, IP multicast routing, RIP, basic IPv6 management, the OSPF Protocol (for routed access only). The license supports up to 4094 VLANs.
IP Services—Provides a richer set of enterprise-class intelligent services and full IPv6 support. It includes all IP Base features plus full Layer 3 routing (IP unicast routing and IP multicast routing). The IP Services feature set includes protocols such as the EIGRP, OSPF Protocol. The license supports up to 4094 VLANs.

Add-On Licenses

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.
Evaluation—a license that is not registered.

License Levels - Usage Guidelines

A permanent license can be moved from one device to another.
A switch stack cannot contain mixed license levels. Also, the switches must be of the same platform.
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.

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

Procedure

Step 1

Begin by establishing a connection from your network to Cisco Smart Software Manager on cisco.com.

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.

Accept the Smart Software Licensing Agreement.
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.

What to do next

Register and convert traditional licenses to Smart Licenses

Converting Traditional Licenses to Smart Licenses

For Cisco Catalyst 3850 Series Switches, after you have upgraded the software image and deployed Smart Licensing, all traditional licenses on the device must be migrated, to Cisco Smart Software Manager. This is a one-time migration process that you must complete on each device.

Procedure

Step 1

Register the device

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 a Device in CSSM.

Step 2

Migrate base licenses

The system converts traditional licenses to smart licenses and sends migration data to Cisco Smart Software Manager, which in turn Cisco Smart Software Manager creates license entitlements and deposits them in your user account. In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Migrating a License with License Conversion..

With this

The device is now in an authorized state and ready to use.
The licenses that you have purchased are displayed in your Smart Account.

How Upgrading or Downgrading Software Affects Smart Licensing

Starting from Cisco IOS XE Fuji 16.9.1, Smart Licensing is the default and only license management solution; all licenses are managed as Smart Licenses.

Important

Starting from Cisco IOS XE Fuji 16.9.1, the Right-To-Use (RTU) licensing mode is deprecated, and the associated license right-to-use command is no longer available on the CLI.

Note how upgrading to a release that supports Smart Licensing or moving to a release that does not support Smart Licensing affects licenses on a device:

When you upgrade from an earlier release to one that supports Smart Licensing—all existing licenses remain in evaluation mode until registered in Cisco Smart Software Manager and then converted. After conversion, they are made available in your Smart Account.

In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Registering a 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.

System Feature	Maximum Limit
Number of HTTP session redirections system-wide	Up to 100 clients per second
Number of HTTPS session redirections system-wide	Up to 20 clients per second

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.
- Cisco TrustSec cannot be configured on a pure bridging domain with the IPSG feature enabled. You must either enable IP routing or disable the IPSG feature in the bridging domain.
- Dynamic SGACL download is limited to 6KB per destination group tag (DGT)
DHCP Client—Starting with Cisco IOS XE Denali 16.1.x, a DHCP client that includes option 61 (used by DHCP clients to specify their unique client identifier) in their DHCP discover/offer packet must accept the response message with option 61 from the DHCP server/relay. A client that fails to accept the response message with option 61, is not in compliance with RFC 6842 and requires a firmware upgrade.
Centralized Management Mode (CMM)—Starting with Cisco IOS XE Denali 16.3.1, CMM is not supported.
Flexible NetFlow—You cannot configure NetFlow export using the Ethernet Management port (GigabitEthernet0/0).
Flex Links are not supported. We recommend that you use spanning tree protocol (STP) as the alternative.
In-Service Software Upgrade (ISSU)
- While performing ISSU from Cisco IOS XE Fuji 16.9.x to Cisco IOS XE Gibraltar 16.12.x, if interface-id snmp-if-index command is not configured with OSPFv3, packet loss can occur. Configure the interface-id snmp-if-index command either during the maintenance window or after isolating the device (by using maintenance mode feature) from the network before doing the ISSU.
- ISSU from Cisco IOS XE Fuji 16.9.x to Cisco IOS XE Gibraltar 16.12.x is not supported in the FIPs mode of operation.
- 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.
Stack ports buffer is not shared as part of the shared pool. The dedicated buffer for stack ports can only be used by stack ports.
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.
UPoE connections—On the WS-C3850-12X48U-L, WS-C3850-12X48U-S and WS-C3850-12X48U-E switch models, a maximum of 28 ports are available for UPoE connections.
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—Autoconversion to password type 6 is supported from Cisco IOS XE Gibraltar 16.12.1 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.

Caveats

Caveats describe unexpected behavior in Cisco IOS-XE releases. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved.

Cisco Bug Search Tool

The Cisco Bug Search Tool (BST) allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The BST is designed to improve the effectiveness in network risk management and device troubleshooting. The tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.
