Software Features in Cisco IOS XE Fuji 16.8.1a
|
Feature Name |
Description and License Level Information |
||
|---|---|---|---|
|
Audio Video Bridging (AVB): IEEE 802.1BA |
Refers to standard IEEE 802.1 BA - AVB. This feature defines a mechanism whereby endpoints and the network function as a whole, to enable high-quality streaming of professional audio and video (AV) over an Ethernet infrastructure. Instead of one-to-one, the network transport enables many-to-many seamless plug-n-play connections for multiple AV endpoints including talkers and listeners. AVB is composed of the following:
(Network Advantage) |
||
|
AVC: NBAR2 attribute support for QoS |
Wired Application Visibility and Control (Wired AVC) Attribute-based QoS (EasyQoS)—Support for defining QoS classes and policies based on Network-Based Application Recognition (NBAR) attributes instead of specific protocols, is available, with a few limitations. Only business-relevance and traffic-class are the supported NBAR attributes. (DNA Advantage) |
||
|
Boot Integrity Visibility |
Allows Cisco's platform identity and software integrity information to be visible and actionable. Platform identity provides the platform’s manufacturing installed identity, and software integrity exposes boot integrity measurements that can be used to assess whether the platform has booted trusted code. (Network Essentials and Network Advantage) |
||
|
DHCPv6: Client Link-Layer Address Option (RFC 6939) |
Defines an optional mechanism and the related DHCPv6 option to allow first-hop DHCPv6 relay agents (relay agents that are connected to the same link as the client) to provide the client's link-layer address in the DHCPv6 messages being sent towards the server. (Network Essentials and Network Advantage) |
||
|
DHCPv6: Support for Option 52 and DNS Search List (DNSSL) Option |
Wireless access points use the The Dynamic Host Configuration Protocol version 6 (DHCPv6) option 52 (RFC 5417) to supply the IPv6 management interface addresses of the primary, secondary, and tertiary wireless controllers. The DNSSL option is a list of DNS suffix domain names used by IPv6 hosts when they perform DNS query searches for short, unqualified domain names. The DNSSL option contains one or more domain names. (Network Essentials and Network Advantage) |
||
|
Support for validation of DHCP Option 125 |
DHCP option 125 is used by DHCP clients and servers to identify vendor-specific information. Support for validation of DHCP option 125 is enabled if the switch is configured as a DHCP relay agent or if the DHCP snooping feature is turned on. Note that the switch drops those packets that do not conform to the RFC3925 format (HEX format) of option 125. |
||
|
Hitless ACL Updates (IPv4 and IPv6) |
Provides the capability to apply existing features to incoming traffic while updating new features in the TCAM. The feature prevents TCAM reprogramming everytime there is a change in an IPv4 or IPv6 ACL on a given interface. (Network Advantage) |
||
|
IEEE 1588v2, Precision Time Protocol (PTP) support |
PTP is defined in IEEE 1588 as Precision Clock Synchronization for Networked Measurements and Control Systems, and was developed to synchronize the clocks in packet-based networks that include distributed device clocks of varying precision and stability. A PTP profile is the set of allowed PTP features applicable to a device. Only the default profile is available in Cisco IOS XE Fuji 16.8.1a. (Network Advantage) |
||
|
IGMP packet forwarding in IEEE 802.1Q Tunneling |
This enhancement enables Internet Group Management Protocol (IGMP) packet forwarding in IEEE 802.1Q tunnels (Network Essentials and Network Advantage) |
||
|
IP-aware Ingress Netflow on VRF Interfaces |
Enables the collection of virtual routing and forwarding (VRF) IDs from incoming packets on a device by applying an input flow monitor having a flow record that collects the VRF ID as a key or a non-key field. IP-aware VRF ingress Netflow is supported only on the ingress traffic with IPv4, IPv6 and Multicast Virtual Private Network version 4 (MVPNv4) as Customer Edge Router (CE) facing interface. (Network Advantage) |
||
|
IPv6 support for IEEE 802.1Q Tunneling |
Enables IPv6 support for the existing 802.1Q tunneling feature. 802.1Q tunneling, also known as Q-in-Q, enables service providers to use a single VLAN to support customers who have multiple VLANs, while preserving customer VLAN IDs and keeping traffic in different customer VLANs segregated. A port configured to support 802.1Q tunneling is called a tunnel port. When you configure tunneling, you assign a tunnel port to a VLAN ID that is dedicated to tunneling. (Network Essentials and Network Advantage) |
||
|
IPv6 support for Cisco TrustSec Security Group Tag (SGT) inline tagging |
Enables IPv6 support for Cisco TrustSec SGT inline tagging. The SGT is a single label (identity tag) indicating the privileges of the source within the network. It is propagated between network hops, and allows any intermediary devices (switches or routers) to enforce policies based on the identity tag. Cisco TrustSec capable devices can send and receive packets with an SGT embedded in the MAC layer (Layer 2). (Network Advantage) |
||
|
IPv6 support for SGACL Policy Enforcement |
Enables IPv6 support for Cisco TrustSec Security Group Access Control List (SGACL) Policy Enforcement. An SGACL associates a Security Group Tag (SGT) with a policy. The policy is enforced upon SGT-tagged traffic egressing the Cisco TrustSec domain. (Network Advantage) |
||
|
Media Access Control Security (MACsec): MACsec host link encryption |
Support for 128-bit AES MACsec (IEEE 802.1AE) encryption with MACsec Key Agreement (MKA) on downlink ports is enabled. 128-bit—(Network Essentials and Network Advantage) |
||
|
MACsec: Must-Secure Support for SW-SW MACsec (128-bit and 256-bit encryption) |
Support for the must-secure feature is enabled for MKA uplink. With must-secure, all the packets in data traffic are encrypted and unencrypted packets are dropped.
|
||
|
MACsec enhancements—MACsec Variable length CKN and Optional support for ICV |
128-bit—(Network Essentials and Network Advantage) |
||
|
OCSP multiple response handling |
Enables support to handle multiple Online Certificate Status Protocol (OCSP) single responses on an OCSP client. (Network Advantage) |
||
|
Programmability |
(Network Essentials and Network Advantage) |
||
|
Secure Storage of Encryption Keys and Passwords |
Secures critical configuration, keys, and passwords by encrypting them. An instance-unique encryption key is stored in the hardware trust anchor to prevent it from being compromised. This feature is enabled on platforms that come with a hardware trust anchor, by default and is not supported on platforms that do not have a hardware trust anchor. (Network Essentials and Network Advantage) |
||
|
Simplified Factory Reset |
Removes all customer specific data that has been added to the device since the time of its shipping. Data erased includes configurations, logfiles, bootvariables, corefiles, and credentials. (Network Essentials and Network Advantage) |
||
|
Transmission Control Protocol (TCP) Maximum Segment Size (MSS) Adjustment |
Enables configuration of the maximum segment size for transient packets that traverse the device during a TCP session. (Network Essentials and Network Advantage) |
||
|
Virtual Ethernet Port Aggregator (VEPA) |
Also referred to as reflective relay, the feature moves switching out of the server, back to the physical network, and makes all virtual machine traffic visible to the external network switch. This frees up server resources to support virtual machines. VEPA provides several benefits to Virtual Ethernet Bridge (VEB), which is a physical end station capability that supports local bridging between multiple virtual end stations. (Network Essentials and Network Advantage) |
||
|
VRF-Aware SGACL Logging |
Enables logging of a Virtual Routing and Forwarding (VRF) name in Security Group Access Control List (SGACL) logs, making them VRF aware. (DNA Advantage) |

Complete List of Supported Features
For the complete list of features supported on a platform, see the Cisco Feature Navigator at https://www.cisco.com/go/cfn.
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. For information about CLI help, see Understanding the Help System. Such hidden commands are only meant to assist Cisco TAC in advanced troubleshooting and are therefore not documented.
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. 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. |

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.
For subsequent Cisco IOS XE Everest 16.x.x, or Cisco IOS XE Fuji 16.x.x releases, if there is a new bootloader in that 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. |
|
Scenario |
Automatic Boot Loader Response |
|---|---|
|
If you boot Cisco IOS XE Fuji 16.8.1a first time |
The boot loader may be upgraded to version 16.8.1r. For example:
If the automatic boot loader upgrade occurs, while booting Cisco IOS XE Fuji 16.8.1a, you will see the following on the console: |
Automatic Microcode Upgrade
During a Cisco IOS image upgrade or downgrade on a PoE or UPoE switch, the microcode is updated to reflect applicable feature enhancements and bug fixes. Do not restart the switch during the upgrade or downgrade process.
It takes approximately an additional 4 minutes to complete the microcode upgrade in addition to the normal reload time; however, data traffic continues to be forwarded during the upgrade. The microcode update 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.

|
Step 4 |
Software install image to flash
You can point to the source image on your TFTP server or in flash if you have it copied to flash. 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 (flash-3): The following sample output displays installation of the Cisco IOS XE Fuji 16.8.1a software image to flash, by using the request platform software package install command, for upgrade scenario Cisco IOS XE Everest 16.5.1a to Cisco IOS XE Fuji 16.8.1a.

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 9300 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.
Using Smart Accounts
We recommend that you assign a Smart Account when you order devices or licenses. Smart Accounts enable you to manage all of your software licenses for switches, routers, firewalls, access-points or tools from one centralized website.
-
Create Smart Accounts by going to https://software.cisco.com → Administration → Request Smart Account.
-
Manage your licenses by going to https://software.cisco.com → Administration → Manage Smart Account.
Note
This is especially relevant to the term licenses that you order, because information about the expiry of term licenses is available only through your Smart Account.
For more information about Smart Accounts and Smart Software Licensing in general, go to the Cisco Smart Software Manager (Cisco SSM) website on cisco.com: http://www.cisco.com/c/en/us/buy/smart-accounts/software-licensing.html
The possible deployment modes are:
-
The right-to-use (RTU) licensing mode—Supported on Cisco Catalyst 9000 Series Switches. See The RTU Licensing Mode.
-
The Smart Licensing mode—Currently not supported on Cisco Catalyst 9000 Series Switches. It is on the roadmap for future releases.
The RTU Licensing Mode
This is the currently supported licensing mode for Cisco Catalyst 9000 Series Switches.
Right-to-use (RTU) licensing allows you to order and activate a specific license type for a given license level, and then to manage license usage on your switch.
Note |
The RTU licensing structure has been modified to match the packaging model that will be used with Smart Licensing mode in the future. Unified licensing structures across the RTU and Smart Licensing modes, along with usage reports, will simplify migration and reduce the implementation time required for Smart Licensing. |
The license right-to-use command (privilege EXEC mode) provides options to activate or deactivate any license supported on the platform.
Options for Base Licenses
license right-to-use [activate | deactivate] [network-essentials | network-advantage] [all | evaluation | subscription {all | slot <1-8>}] [acceptEULA]Options for Add-On Licenses
license right-to-use [activate | deactivate]addon [dna-essentials | dna-advantage] [all | evaluation | subscription {all | slot <1-8>}] [acceptEULA]Usage Guidelines for the RTU Licensing Mode
-
Base licenses (Network Essentials and Network-Advantage) may be ordered only with a permanent license type.
-
Add-on licenses (DNA Essentials and DNA Advantage) may be ordered only with a term license type.
-
You can set up Cisco SSM to receive daily e-mail alerts, to be notified of expiring add-on licenses that you want to renew.
-
You must order an add-on license in order to purchase a switch. On term expiry, you can either renew the add-on license 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 3. Permitted Combinations DNA Essentials
DNA Advantage
Network Essentials
Yes
No
Network Advantage
Yes5
Yes
5 For this combination, the DNA-Essentials license must be ordered separately using Cisco SSM. -
The following features are currently available only at the Network Advantage license level. However, the correct minimum license level for these features is Network Essentials and the CFN reflects this correct license level. You will be able to configure these features with a Network Essentials license level after the correction is made in an upcoming release:
-
IPv6 Multicast
-
IPv6 ACL Support for HTTP Servers
-
-
Evaluation licenses cannot be ordered. They can be activated temporarily, without purchase. Warning system messages about the evaluation license expiry are generated 10 and 5 days before the 90-day window. Warning system messages are generated every day after the 90-day period. An expired evaluation license cannot be reactivated after reload.
For detailed configuration information about using the RTU Licensing Mode, see the System Management Configuration Guide → Configuring Right-To-Use Licenses chapter for your release.
Scaling Guidelines
For information about feature scaling guidelines, see the Cisco Catalyst 9300 Series Switches datasheet at:
Limitations and Restrictions
-
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 40GBASE-CR4 QSFP 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.
Note
There is no option to turn autonegotiation off on the ports which connect to Cisco 40GBASE-CR4 QSFP cable.
-
-
Interoperability limitations:
-
If one end of the link has a device running Cisco IOS XE Everest 16.6.1 or Cisco IOS XE Everest 16.6.2 or Cisco IOS XE Everest 16.6.3 and the other end is running Cisco IOS XE Fuji 16.8.1a, the link does not come up. To avoid this interoperability issue between releases, it is recommended to use the same image across all the Catalyst 9000 Series Switches in the network.
-
-
Memory leak—When a logging discriminator is configured and applied to a device, memory leak is seen under heavy syslog or debug output. The rate of the leak is dependent on the quantity of logs produced. In extreme cases, the device may fail. As a workaround, disable the logging discriminator on the device.
-
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:
-
A switch stack supports up to eight stack members.
-
Mixed stacking is not supported. Cisco Catalyst 9300 Series Switches cannot be stacked with Cisco Catalyst 3850 Series Switches.
-
Auto upgrade for a new member switch is supported only in the install mode.
-
-
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.
-
Wired Application Visibility and Control limitations:
-
NBAR2 (QoS and Protocol-discovery) configuration is allowed only on wired physical ports. It is not supported on virtual interfaces, for example, VLAN, port channel nor other logical interfaces.
-
NBAR2 based match criteria ‘match protocol’ is allowed only with marking or policing actions. NBAR2 match criteria will not be allowed in a policy that has queuing features configured.
-
‘Match Protocol’: up to 256 concurrent different protocols in all policies.
-
NBAR2 and Legacy NetFlow cannot be configured together at the same time on the same interface. However, NBAR2 and wired AVC Flexible NetFlow can be configured together on the same interface.
-
Only IPv4 unicast (TCP/UDP) is supported.
-
AVC is not supported on management port (Gig 0/0)
-
NBAR2 attachment should be done only on physical access ports. Uplink can be attached as long as it is a single uplink and is not part of a port channel.
-
Performance—Each switch member is able to handle 2000 connections per second (CPS) at less than 50% CPU utilization. Above this rate, AVC service is not guaranteed.
-
Scale—Able to handle up to 20000 bi-directional flows per 24 access ports and per 48 access ports.
-
-
YANG data modeling limitation—A maximum of 20 simultaneous NETCONF sessions are supported.
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
