Release Notes for Cisco Catalyst 9300 Series Switches, Cisco IOS XE Amsterdam 17.1.x
Introduction
Cisco Catalyst 9300 Series Switches are Cisco’s lead stackable access platforms for the next-generation enterprise and have been purpose-built to address emerging trends of Security, IoT, Mobility, and Cloud.
They deliver complete convergence with the rest of the Cisco Catalyst 9000 Series Switches in terms of ASIC architecture with a Unified Access Data Plane (UADP) 2.0. 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). This series forms the foundational building block for SD-Access, which is Cisco’s lead enterprise architecture.

Introduces IPv6 support for Encapsulated Remote Switched Port Analyzer (ERSPAN). ERSPAN enables you to monitor traffic on ports or VLANs, and send the monitored traffic to destination ports.
See Network Management → Configuring ERSPAN.
(DNA Advantage) |
Flash MIB instance retrieval count limit increase |
The limitation of Flash MIB listing 100 files per partition per device has been removed. Flash MIB can now fetch all the files from the flash file system.
See Network Management → Configuring Simple Network Management Protocol.
(Network Essentials and Network Advantage) |
IGMP (IPv4) : VPLS Layer 2 Snooping |
Introduces support for Internet Group Management Protocol (IGMP) snooping on a Virtual Private LAN Service (VPLS) configured network.
See Multiprotocol Label Switching → Configuring Virtual Private LAN Service (VPLS) and VPLS BGP-Based Autodiscovery.
(Network Advantage) |
Ingress and Egress Flexible Netflow on MPLS |
Allows capture of IP flow information for packets undergoing Multiprotocol Label Switching (MPLS) label imposition when entering an MPLS network. These packets arrive on a device as IP packets and are transmitted as MPLS packets. Enable the feature by configuring an ingress flow monitor for IPv4 and IPv6 traffic at the customer edge (CE) facing side of the provider edge (PE) node.
See Network Management → Configuring Flexible NetFlow.
(DNA Essentials and DNA Advantage) |
MACsec over Ethernet over MPLS (EoMPLS) |
In VLAN mode, the switch (PE device) can now process packets in which the 802.1Q tag is not encrypted by the CE device.
See Multiprotocol Label Switching → Configuring Ethernet-over-MPLS and Pseudowire Redundancy .
(Network Advantage) |
MPLS VPN InterAS Option A |
MPLS VPN InterAS options provide multiple ways of interconnecting VPNs between different MPLS VPN service providers. With one of the options configured, a customer’s site can exist on several carrier networks (autonomous systems) and still have seamless VPN connectivity. Of the available InterAS options, MPLS VPN InterAS Option A is the simplest to configure. This option provides back-to-back virtual routing and forwarding (VRF) connectivity (MPLS VPN providers exchange routes across VRF interfaces).
See Multiprotocol Label Switching → Configuring MPLS VPN InterAS Options.
(Network Advantage) |
Multicast VPN Extranet Support |
Enables service providers to distribute IP multicast content originating from one enterprise site to other enterprise sites.
See IP Multicast Routing → Configuring Multicast VPN Extranet Support.
(Network Advantage) |
Neighbor Discovery (ND) Inspection Feature Deprecation |
The IPv6 ND Inspection feature is deprecated. The Switch Integrated Security Features based (SISF-based) device tracking feature replaces it and offers the same capabilities.
See Security → Configuring IPv6 First Hop Security.
(Network Essentials and Network Advantage) |
Opening or Closing SNMP UDP Ports |
A security enhancement that enables you to access the Simple Network Management Protocol (SNMP) UDP ports only after one of the requisite commands is configured. This design change secures and opens the ports only when required and prevents a device from listening to a port unnecessarily.
See Network Management → Configuring Simple Network Management Protocol.
(Network Essentials and Network Advantage) |
Per-Port MTU Configuration |
Introduces support for port level and port channel level maximum transmission unit (MTU) configuration. With Per-Port MTU configuration, you can configure different MTU values for different interfaces as well as for different port channel interfaces.
See Interface and Hardware Components → Configuring Per-Port MTU.

ROMMON Versions
ROMMON, also known as the boot loader, is firmware that runs when the device is powered up or reset. It initializes the processor hardware and boots the operating system software (Cisco IOS XE software image). The ROMMON is stored on the following Serial Peripheral Interface (SPI) flash devices on your switch:
-
Primary: The ROMMON stored here is the one the system boots every time the device is powered-on or reset.

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.

Upgrading the ROMMON
To know the ROMMON or bootloader version that applies to every major and maintenance release, see ROMMON Versions.
You can upgrade the ROMMON before, or, after upgrading the software version. If a new ROMMON version is available for the software version you are upgrading to, proceed as follows:
-
Upgrading the ROMMON in the primary SPI flash device
This ROMMON is upgraded automatically. When you upgrade from an existing release on your switch to a later or newer release for the first time, and there is a new ROMMON version in the new release, the system automatically upgrades the ROMMON in the primary SPI flash device, based on the hardware version of the switch when you boot up your switch with the new image for the first time.
-
Upgrading the ROMMON in the golden SPI flash device
You must manually upgrade this ROMMON. Enter the upgrade rom-monitor capsule golden switch command in privileged EXEC mode.
Note |
In case of a switch stack, perform the upgrade on the active switch and all members of the stack. |
After the ROMMON is upgraded, it will take effect on the next reload. If you go back to an older release after this, the ROMMON is not downgraded. The updated ROMMON supports all previous releases.
Automatic Microcode Upgrade
During a Cisco IOS image upgrade or downgrade on a PoE or UPoE switch, microcode is upgraded to reflect applicable feature enhancements and bug fixes. A microcode upgrade occurs only during an image upgrade or downgrade, on PoE or UPoE switches. It does not occur during switch reloads or on non-PoE switches.
Depending on the release you are upgrading from, microcode upgrade can occur during the install operation or during bootup:
-
If the release you are upgrading from does not support microcode updates during the course of installation, microcode is updated during boot up, and an additional 4 minutes (approximately) are required to complete the microcode upgrade, in addition to the normal reload time. Data traffic is not forwarded when microcode is upgraded during bootup.
-
When using install commands to upgrade, microcode is upgraded during the install operation, and no additional time is required during bootup. Here microcode is updated before the reload that occurs as part of the image upgrade process. Data traffic continues to be forwarded during the upgrade.
Do not restart the switch during the upgrade or downgrade process.

Cisco IOS XE Gibraltar 16.12.x or earlier releases |
Starting from Cisco IOS XE Gibraltar 16.12.1, a new microcode is introduced to support IEEE 802.3bt Type 3 standard for UPOE switches in the series (C9300-24U, C9300-48U, C9300-24UX, C9300-48UXM, C9300-48UN). The new microcode is not backward-compatible with some releases, because of which you must also downgrade the microcode when you downgrade to one of these releases. If the microcode is not downgraded, PoE features will be impacted after the downgrade.
Depending on the release you are downgrading to and the commands you use to downgrade, review the table below for the action you may have to take:

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.
License Levels - Usage Guidelines
-
Base licenses (Network Essentials and Network-Advantage) are ordered and fulfilled only with a permanent license type.
-
Add-on licenses (DNA Essentials and DNA Advantage) are ordered and fulfilled only with a term license type.
-
An add-on license level is included when you choose a network license level. If you use DNA features, renew the license before term expiry, 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 4. Permitted Combinations DNA Essentials
DNA Advantage
Network Essentials
Yes
No
Network Advantage
Yes5
Yes
5 You will be able to purchase this combination only at the time of the DNA license renewal and not when you purchase DNA-Essentials the first time. -
Evaluation licenses cannot be ordered. They are not tracked via Cisco Smart Software Manager and expire after a 90-day period. Evaluation licenses can be used only once on the switch and cannot be regenerated. Warning system messages about an evaluation license expiry are generated only 275 days after expiration and every week thereafter. An expired evaluation license cannot be reactivated after reload. This applies only to Smart Licensing. The notion of evaluation licenses does not apply to Smart Licensing Using Policy.
Cisco Smart Licensing
Cisco Smart Licensing is a flexible licensing model that provides you with an easier, faster, and more consistent way to purchase and manage software across the Cisco portfolio and across your organization. And it’s secure – you control what users can access. With Smart Licensing you get:
-
Easy Activation: Smart Licensing establishes a pool of software licenses that can be used across the entire organization—no more PAKs (Product Activation Keys).
-
Unified Management: My Cisco Entitlements (MCE) provides a complete view into all of your Cisco products and services in an easy-to-use portal, so you always know what you have and what you are using.
-
License Flexibility: Your software is not node-locked to your hardware, so you can easily use and transfer licenses as needed.
To use Smart Licensing, you must first set up a Smart Account on Cisco Software Central (http://software.cisco.com).
Important |
Cisco Smart Licensing is the default and the only available method to manage licenses. |
For a more detailed overview on Cisco Licensing, go to cisco.com/go/licensingguide.
Deploying Smart Licensing
The following provides a process overview of a day 0 to day N deployment directly initiated from a device that is running Cisco IOS XE Fuji 16.9.1 or later releases. Links to the configuration guide provide detailed information to help you complete each one of the smaller tasks.
Procedure
Step 1 |
Begin by establishing a connection from your network to Cisco Smart Software Manager on cisco.com. In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Connecting to CSSM |
Step 2 |
Create and activate your Smart Account, or login if you already have one. To create and activate Smart Account, go to Cisco Software Central → Create Smart Accounts. Only authorized users can activate the Smart Account. |
Step 3 |
Complete the Cisco Smart Software Manager set up. |
With this,
-
The device is now in an authorized state and ready to use.
-
The licenses that you have purchased are displayed in your Smart Account.
Using Smart Licensing on an Out-of-the-Box Device
Starting from Cisco IOS XE Fuji 16.9.1, if an out-of-the-box device has the software version factory-provisioned, all licenses on such a device remain in evaluation mode until registered in Cisco Smart Software Manager.
In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Registering the Device in CSSM
How Upgrading or Downgrading Software Affects Smart Licensing
Starting from Cisco IOS XE Fuji 16.9.1, Smart Licensing is the default and only license management solution; all licenses are managed as Smart Licenses.
Important |
Starting from Cisco IOS XE Fuji 16.9.1, the Right-To-Use (RTU) licensing mode is deprecated, and the associated license right-to-use command is no longer available on the CLI. |
Note how upgrading to a release that supports Smart Licensing or moving to a release that does not support Smart Licensing affects licenses on a device:
-
When you upgrade from an earlier release to one that supports Smart Licensing—all existing licenses remain in evaluation mode until registered in Cisco Smart Software Manager. After registration, they are made available in your Smart Account.
In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Registering the Device in CSSM
-
When you downgrade to a release where Smart Licensing is not supported—all smart licenses on the device are converted to traditional licenses and all smart licensing information on the device is removed.
Scaling Guidelines
For information about feature scaling guidelines, see the Cisco Catalyst 9300 Series Switches datasheet at:
Limitations and Restrictions
-
Control Plane Policing (CoPP)—The show run command does not display information about classes configured under
system-cpp policy
, when they are left at default values. Use the show policy-map system-cpp-policy or the show policy-map control-plane commands in privileged EXEC mode instead. -
Cisco TrustSec restrictions—Cisco TrustSec can be configured only on physical interfaces, not on logical interfaces.
-
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 layer 2 port-channels, loopback, tunnels.
-
You can not configure multiple flow monitors of same type (ipv4, ipv6 or datalink) on the same interface for same direction.
-
-
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.
-
Stack Queuing and Scheduling (SQS) drops CPU bound packets exceeding 1.4 Gbps.
-
-
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.
-
Only homogenous stacking is supported, mixed stacking is not.
C9300 SKUs can be stacked only with other C9300 SKUs. Similarly C9300L SKUs can be stacked only with other C9300L SKUs.
The following additional restriction applies to the C9300-24UB, C9300-24UXB, and C9300-48UB models of the series: These models can be stacked only with each other. They cannot be stacked with other C9300 SKUs.
-
Auto upgrade for a new member switch is supported only in the install mode.
-
-
TACACS legacy command: Do not configure the legacy tacacs-server host command; this command is deprecated. If the software version running on your device is Cisco IOS XE Gibraltar 16.12.2 or a later release, using the legacy command can cause authentication failures. Use the tacacs server command in global configuration mode.
-
USB Authentication—When you connect a Cisco USB drive to the switch, the switch tries to authenticate the drive against an existing encrypted preshared key. Since the USB drive does not send a key for authentication, the following message is displayed on the console when you enter password encryption aes command:
Device(config)# password encryption aes Master key change notification called without new or old key
-
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.
-
Embedded Event Manager—Identity event detector is not supported on Embedded Event Manager.
-
The File System Check (fsck) utility is not supported in install mode.
