Software Features in Cisco IOS XE Fuji 16.8.1a
Feature Name |
Description and License Level Information |
||
---|---|---|---|
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.
(IP Base and IP Services) |
||
Cisco StackWise Virtual |
Cisco StackWise Virtual is a network system virtualization technology that pairs two switches into one virtual switch to simplify operational efficiency with a single control and management plane.
Starting with this release, the feature is also supported on the following models of the Cisco Catalyst 3850 Series Switches:
(IP Base and IP Services) |
||
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.
(LAN Base, IP Base, and IP Services) |
||
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.
(LAN Base, IP Base, and IP Services) |
||
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. |
||
Fast Software Upgrade (FSU) |
Reduces traffic downtime during a software upgrade or reload. The fast software upgrade feature is supported on both stacking and standalone systems.
(LAN Base, IP Base, and IP Services) |
||
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.
(IP Services) |
||
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.
(IP Base and IP Services) |
||
IGMP packet forwarding in IEEE 802.1Q Tunneling |
This enhancement enables Internet Group Management Protocol (IGMP) packet forwarding in IEEE 802.1Q tunnels
(LAN Base, IP Base, and IP Services) |
||
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.
(IP Services) |
||
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.
(LAN Base, IP Base, and IP Services) |
||
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.
(IP Base and IP Services) |
||
Media Access Control Security (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.
(LAN Base, IP Base, and IP Services) |
||
MACsec enhancements—MACsec Variable length CKN and Optional support for ICV |
(IP Base and IP Services) |
||
OCSP multiple response handling |
Enables support to handle multiple Online Certificate Status Protocol (OCSP) single responses on an OCSP client.
(IP Services) |
||
Programmability |
(LAN Base, IP Base, and IP Services) |
||
Right-To-Use (RTU) Add-On Licenses |
Enables configuration of the DNA Essentials and DNA Advantage add-on licenses on the switch. 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). Add-On Licenses require an RTU image-based as a pre-requisite:
A license level does not apply |
||
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.
(IP Base and IP Services) |
||
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.
(IP Base and IP Services) |

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. |

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
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.

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 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. |
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 4.68. 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.
Starting with Cisco IOS XE Denali 16.1.1 and all later releases: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.

Licensing
Feature Sets and Right-To-Use Licensing
This section provides information about the licensing packages for feature sets available on Cisco Catalyst 3850 Series Switches
License Levels
The features available on the switch can be classifed into those available with the image-based license levels and those available with add-on license levels.
Image-Based Licenses—The licenses levels that you can order and the corresponding feature sets are:
-
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—These require an image-bases license as a prerequisite. 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). The add-on licenses that you can order are:
-
Digital Networking Architecture (DNA) Essentials—This add-on license can be purchased with LAN Base, IP Base, or IP Services image-based licenses.
DNA Advantage (Contains DNA Essentials plus more)—This add-on license can be purchased only with IP Base or IP Services image-based licenses.
License Types
The types of licenses available to order by duration are:
-
Permanent—For image-based licenses only. Purchased with a specific feature set with no expiration date.
-
Term—For add-on licenses only. Purchased with a feature set for a specific subscription period of 3, 5, or 7 years. The expiration date displays on Cisco Smart Software Manager (Cisco SSM).
-
Evaluation licenses—Available with image-based and add-on licenses. Pre-installed on the switch and valid for only a 90 day in-use period.
Right-to-use (RTU) Licensing
The Right-to-use (RTU) licensing feature allows you to configure and activate a specific license type and level, and then to manage license usage on your switch.
Added licensing information is also available in the product data sheet, at this URL: https://www.cisco.com/en/US/products/ps12686/products_data_sheets_list.html
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

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
-
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)
-
-
Centralized Management Mode (CMM)—Starting with Cisco IOS XE Denali 16.3.1, CMM is not supported.
-
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. -
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.
-
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.
-
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.

-
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.
