Release Notes for Cisco Catalyst 9300 Series Switches, Cisco IOS XE Cupertino 17.7.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.

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.
-
Golden: The ROMMON stored here is a backup copy. If the one in the primary is corrupted, the system automatically boots the ROMMON in the golden SPI flash device.
ROMMON upgrades may be required to resolve firmware defects, or to support new features, but there may not be new versions with every release.

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.
Software Images
Release |
Image Type |
File Name |
---|---|---|
Cisco IOS XE Cupertino 17.7.1 |
CAT9K_IOSXE |
cat9k_iosxe.17.07.01.SPA.bin |
No Payload Encryption (NPE) |
cat9k_iosxe_npe.17.07.01.SPA.bin |
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.
-
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.

For a more detailed overview on Cisco Licensing, go to Cisco Software Licensing Guide.
License Levels - Usage Guidelines
-
The duration or term for which a purchased license is valid:
Smart Licensing Using Policy
Smart Licensing
-
Perpetual: There is no expiration date for such a license.
-
Subscription: The license is valid only until a certain date (for a three, five, or seven year period).
-
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.
-
-
Base licenses (Network Essentials and Network-Advantage) are ordered and fulfilled only with a perpetual or permanent license type.
-
Add-on licenses (DNA Essentials and DNA Advantage) are ordered and fulfilled only with a subscription or 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 5. Permitted Combinations DNA Essentials
DNA Advantage
Network Essentials
Yes
No
Network Advantage
Yes8
Yes
8 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.
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.
-
-
Hardware Limitations — Optics:
-
SFP-10G-T-X supports 100Mbps/1G/10G speeds based on auto negotiation with the peer device. 10Mbps speed is not supported and you cannot force speed settings from the transceiver.
-
PHY Loopback test is not supported on SFP-10G-T-X.
-
-
QoS restrictions
-
When configuring QoS queuing policy, the sum of the queuing buffer should not exceed 100%.
-
Policing and marking policy on sub interfaces is supported.
-
Marking policy on switched virtual interfaces (SVI) is supported.
-
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.
-
-
Smart Licensing Using Policy: Starting with Cisco IOS XE Amsterdam 17.3.2a, with the introduction of Smart Licensing Using Policy, even if you configure a hostname for a product instance or device, only the Unique Device Identifier (UDI) is displayed. This change in the display can be observed in all licensing utilities and user interfaces where the hostname was displayed in earlier releases. It does not affect any licensing functionality. There is no workaround for this limitation.
The licensing utilities and user interfaces that are affected by this limitation include only the following: Cisco Smart Software Manager (CSSM), Cisco Smart License Utility (CSLU), and Smart Software Manager On-Prem (SSM On-Prem).
-
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
-
MACsec is not supported on Software-Defined Access deployments.
-
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.
