Release Notes for Cisco Catalyst 9500 Series Switches, Cisco IOS XE Fuji 16.8.x
Introduction
Cisco Catalyst 9500 Series Switches and Cisco Catalyst 9500 Series Switches - High Performance are Cisco's lead, fixed core and aggregation enterprise switching platforms. They have been purpose-built to address emerging trends of Security, IoT, Mobility, and Cloud.
They deliver complete convergence in terms of ASIC architecture with Unified Access Data Plane (UADP) 2.0 on Cisco Catalyst 9500 Series Switches and UADP 3.0 on Cisco Catalyst 9500 Series Switches - High Performance. The platform runs an Open Cisco IOS XE that supports model driven programmability, has the capacity to host containers, and run 3rd party applications and scripts natively within the switch (by virtue of x86 CPU architecture, local storage, and a higher memory footprint). The series forms the foundational building block for SD-Access, which is Cisco’s lead enterprise architecture.
Note |
With the introduction of the High Performance models in the series, there may be differences in the supported and unsupported features, limitations, and caveats that apply to the Cisco Catalyst 9500 Series Switches and Cisco Catalyst 9500 Series Switches - High Performance models. Throughout this release note document, any such differences are expressly called out. If they are not, the information applies to all models in the series. |

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) |
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) |
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.

Feature Name |
Description, License Level Information, Documentation Link |
---|---|
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) |
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) |
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 9500 Series Switches:
(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) |
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 16.8.1. (Network Advantage) |
IP-aware Ingress Netflow on VRF Interfaces |
IP-aware ingress netflow enables 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 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) |
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) |
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) |
Software Features Introduced on Cisco Catalyst 9500 Series Switches-High Performance

---|---|
Flexible NetFlow: 32 bit AS Number Support |
The autonomous system (AS) number space is a 32 bit field with 4,294,967,296 unique values, which are available for use to support the Internet's public inter-domain routing system. The AS number is required to run BGP and peer with your internet service provider, between internet service providers at peering points, and Internet Exchanges (IX). Flexible NetFlow Version 9 and Flexible NetFlow IPFIX export format support the 32 bit AS number.
(DNA Essentials) |
Flexible NetFlow: NetFlow v5 Export Protocol |
Enables sending of export packets using the Version 5 export protocol.
(DNA Essentials) |
Lawful Intercept |
The process by which law enforcement agencies conduct electronic surveillance as authorized by judicial or administrative order.
(Network Advantage) |
Protocol Independent Multicast (PIM) Snooping |
In networks where a Layer 2 switch interconnects several routers, the switch floods IP multicast packets on all multicast router ports by default, even if there are no multicast receivers downstream. With PIM snooping enabled, the switch restricts multicast packets for each IP multicast group to only those multicast router ports that have downstream receivers joined to that group.
(Network Advantage) |
Quality of Service (QoS) |
These QoS enhancements were introduced
(Network Essentials and Network Advantage) |
Security Group Tag (SGT) Caching |
When the switch receives new IP packets with a valid SGT, the switch can now create a cache containing the source IPv4 address, VRF, and SGT bindings. These IP SGT bindings are used to add the Cisco metadata header back to the outgoing packet after deep packet inspection processing.
(DNA Advantage) |
Unicast over Point-to-Multipoint GRE andMulticast over Point-to-Multipoint GRE |
In a hub-and-spoke topology, multipoint Generic Routing Encapsulation (mGRE) allows multiple destinations to be grouped into a single multipoint interface. It is configured over an IPv4 core or underlying network.
(Network Essentials and Network Advantage) |
VLAN Translation: One-to-One Mapping |
VLAN translation, also known as VLAN mapping, enables service providers to merge two Layer two domains without actually changing their VLAN numbers.
(Network Advantage) |
Bridge Assurance |
Bridge Assurance helps to protect against certain problems that can cause bridging loops in the network. With Bridge Assurance enabled, BPDUs are sent out on all operational network ports for each hello time period. If the port does not receive a BPDU for a specified period, the port is put into a blocked state and is not used in the root port calculation. Once that port receives a BPDU, it resumes the normal spanning tree transitions. Only Rapid PVST+ and MST spanning tree protocols support Bridge Assurance.

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. |

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 9500 Series Switches and Cisco Catalyst 9500 Series Switches - High Performance 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 9500 Series Switches datasheet at:
Limitations and Restrictions
With Cisco Catalyst 9500 Series Switches and Cisco Catalyst 9500 Series Switches - High Performance—If a feature is not supported on a switch model, you do not have to factor in any limitations or restrictons that may be listed here. If limitations or restrictions are listed for a feature that is supported, check if model numbers are specified, to know if they apply. If model numbers are not specified, the limitations or restrictons apply to all models in the series.
-
Cisco StackWise Virtual—When configuring StackWiseVirtual links (SVLs) on the 9500-40X and C9500-16X models of the Cisco Catalyst 9500 Series Switches, note that you cannot create SVLs on any of the uplink modules.
-
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:
-
Use the MODE button to switch-off the beacon LED.
-
All port LED behavior is undefined until interfaces are fully initialized.
-
1G with Cisco QSA Module (CVR-QSFP-SFP10G) is not supported on the uplink ports of the C9500-24Y4C and C9500-48Y4C models.
-
The following limitations apply to Cisco QSA Module (CVR-QSFP-SFP10G) when Cisco 1000Base-T Copper SFP (GLC-T) or Cisco 1G Fiber SFP Module for Multimode Fiber are plugged into the QSA module:
-
1G Fiber modules over QSA do not support autonegotiation. Auto-negotiation should be disabled on the far-end devices.
-
Although visible in the CLI, the command [no] speed nonegotiate is not supported with 1G Fiber modules over QSA.
-
Only GLC-T over QSA supports auto-negotiation.
-
GLC-T supports only port speed of 1000 Mb/s over QSA. Port speeds of 10/100-Mb/s are not supported due to hardware limitation.
-
-
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.
-
When you use Cisco QSFP-4SFP10G-CUxM 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.
-
Autonegotiation is not supported on HundredGigabitEthernet1/0/49 to HundredGigabitEthernet1/0/52 uplink ports of the C9500-48Y4C models, and HundredGigabitEthernet1/0/25 to HundredGigabitEthernet1/0/28 uplink ports of the C9500-24Y4C models. Disable autonegotiation on the peer device if you are using QSFP-H40G-CUxx and QSFP-H40G-ACUxx cables.
-
For QSFP-H100G-CUxx cables, the C9500-48Y4C and C9500-24Y4C models support the cables only if both sides of the connection are either C9500-48Y4C or C9500-24Y4C.
-
-
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.
-
When you use Cisco QSFP-4SFP10G-CUxM Direct-Attach Copper Cables, if one end of the 40G link is a Catalyst 9400 Series Switch and the other end is a Catalyst 9500 Series Switch, the link does not come up, or comes up on one side and stays down on the other. To avoid this interoperability issue between devices, apply the the speed nonegotiate command on the Catalyst 9500 Series Switch interface. This command disables autonegotiation and brings the link up. To restore autonegotiation, use the no speed nonegotiation command.
-
-
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.
-
-
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 500 connections per second (CPS) at less than 50% CPU utilization. Above this rate, AVC service is not guaranteed.
-
Scale—Able to handle up to 5000 bi-directional flows per 24 access ports and 10000 bi-directional flows per 48 access ports.
-
-
YANG data modeling limitation—A maximum of 20 simultaneous NETCONF sessions are supported.
