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.

(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.

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:

  • Generalized Precision Time Protocol (gPTP)—IEEE 802.1AS. Provides a mechanism to synchronize clocks of the bridges and end point devices in an AVB network.

  • Quality of Service (QoS)—IEEE 802.1Qav. Guarantees bandwidth and minimum bounded latency for the time-sensitive audio and video streams.

  • Multiple Stream Reservation Protocol (MSRP)—IEEE 802.1Qat. Provides a mechanism for end stations to reserve network resources that will guarantee the transmission and reception of data streams across a network with the requested bandwidth.

  • Multiple VLAN Registration Protocol (MVRP)—Provides a mechanism for dynamic maintenance of the contents of Dynamic VLAN Registration Entries for each VLAN ID, and for propagating the information they contain to other Bridges.


(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.

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)

Programmability

  • gNMI Operations—Model-driven configuration and retrieval of operational data using the gNMI capabilities, GET and SET RPCs.

  • Guest Shell Logging and Tracing Support—Provides logging services for guest applications that run separately from the host system, to report tracing data to the host file system. The tracing data is saved in an IOX tracelog and the logging data is saved in the IOS syslog, on the host machine.

  • IPXE IPv6 support—iPXE IPv6 network boot is supported.

  • Model Based AAA—Implements the NETCONF Access Control Model (NACM). NACM is a form of role-based access control (RBAC) specified in RFC 6536.

  • NETCONF Global Session Lock and Kill Session—Provides a global lock and the ability to kill non-responsive sessions in NETCONF. During a session conflict or client misuse of the global lock, NETCONF sessions can be monitored via the show netconf-yang sessions command, and non-responsive sessions can be cleared using the clear configuration lock command.

  • NETCONF and RESTCONF Debug commands—Commands for debugging were added.

  • NETCONF and RESTCONF IPv6 Support—Data model interfaces (DMIs) support the use of IPv6 protocol. DMI IPv6 support helps client applications to communicate with services that use IPv6 addresses. External facing interfaces will provide dual-stack support; both IPv4 and IPv6.

  • RESTCONF—Provides an RFC 8040 compliant HTTP-based protocol that provides a programmatic interface for accessing data defined in YANG, using the datastore concepts defined in NETCONF.

  • 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/1681.

    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.

  • Operational Data Parser Polling—Starting with Cisco IOS XE Fuji 16.8.1a, the Operational Data Parser Polling feature is deprecated. All operational data models provide direct operational data model access, hence this feature is no longer required.


(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

(C9500-24Y4C, C9500-32C, C9500-32QC, and C9500-48Y4C)

Feature Name

Description, License Level Information, Documentation Link

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

  • Sharped Queueing—A queuing mode, which is a combination of shared and shaped queuing modes. The queues share bandwidth according to the configured weights, and are rate-limited to the configured shape-value.

  • Classification Type: L2-Miss—A classification type that can be set as a criteria to check an incoming packet. L2-Miss can be configured for both source MAC and destination MAC.

  • L3 Packet Length Classification—Provides the capability to match and classify traffic, based on the Layer 3 packet length in the IP header. The packet length is set as the matching criterion in the class policy-map, to match the value on the incoming packet.

  • Time-to-Live (TTL)—Also a classification feature. You can set TTL as a criterion in the ACL list, and perform a TTL check on the incoming packet. The access control entry is used to check the IPv4 TTL to match the value on the incoming packet.

  • Ingress Packet FIFO (IPF)—Parses incoming network traffic to classify frames into different priorities levels. The traffic class is derived from different packet formats. These traffic classes are further mapped to priority levels, which are used to make drop decisions, in case of congestion.

  • Priority Queue Policer—Supports policing rate on priority queue. Priority queue policer supports only single-rate two-color policing.

  • Weighted Random Early Detection (WRED) enhancements—Wired ports support a maximum of eight physical queues. You can configure WRED on all the eight physical queues.


(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

and

Multicast 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)

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 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:
ROM: IOS-XE ROMMON
BOOTLDR: System Bootstrap, Version 16.8.1r [FC4], RELEASE SOFTWARE (P)
 

If the automatic boot loader upgrade occurs, while booting Cisco IOS XE Fuji 16.8.1a, you will see the following on the console:

%IOSXEBOOT-4-BOOTLOADER_UPGRADE: (rp/0): ### Tue Mar 13 17:58:44 Universal 2018 PLEASE DO NOT POWER CYCLE ### BOOT LOADER UPGRADING
%IOSXEBOOT-4-BOOTLOADER_UPGRADE: (rp/0): boot loader upgrade successful
 

Software Installation Commands


Note

The request platform software commands are deprecated starting from Cisco IOS XE Gibraltar 16.10.1. The commands are visible on the CLI in this release and you can configure them, but we recommend that you use the install commands to upgrade or downgrade.
Note 
This table of commands is not supported on Cisco Catalyst 9500 Series Switches - High Performance.

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://www.cisco.com/go/cfn. 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.comAdministrationRequest Smart Account.

  • Manage your licenses by going to https://software.cisco.comAdministrationManage 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 GuideConfiguring Right-To-Use Licenses chapter for your release.

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.

  • 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.

    • 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.

  • 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.

  • 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.

  • 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.
