Upgrade and Downgrade Guidelines
To get a complete overview of all the possible upgrade paths in Cisco IMC, see Cisco UCS Rack Server Upgrade Support Matrix.
Downgrade Limitation for Release 4.3.4.240152:
See Cisco UCS Rack Server Upgrade Support Matrix to view your server upgrade path.
Downgrade Limitation for Release 4.3.3.240022:
In the release 4.3.3.240022, you cannot downgrade the Cisco UCS M7 servers with 5th Gen Intel® Xeon® processors.
When you try to downgrade Cisco IMC, the following error message is displayed on CLI, GUI, Redfish API and XML API user interfaces:
Error message during BMC downgrade with different interfaces like CLI/WEBUI/Redfish/XML =
“Update aborted. INCOMPATIBLE_IMAGE”
When you try to downgrade BIOS, the following error message is displayed on CLI, GUI, Redfish API and XML API user interfaces:
CPU ID mismatch between uploaded image and the platform.
Note |
You can downgrade Cisco UCS M7 servers with 4th Generation Intel® Xeon® Scalable Processors. |
Infrastructure Upgrade and Downgrade to Release 4.3(2):
-
Cisco UCS M4 servers are not supported by 4.3.2.230207 and later releases.
-
You must perform firmware update after adding any new hardware component to the system.
-
If you are planning to install Cisco UCS VIC 15237 or 15427 in a server, then upgrade the server to 4.3.2.230270 or later versions and then insert the adapter into the server.
If you insert Cisco UCS VIC 15237 or 15427 into the server that is running earlier versions than 4.3.2.230270, then upgrade the server to 4.3.2.230270 or later versions and power cycle the server to recognize the adapter.
-
If you are planning to install Cisco UCS VIC 15235 or 15425 in a server, then upgrade the server to 4.3.2.230207 or later versions and then insert the adapter into the server.
If you insert Cisco UCS VIC 15235 or 15425 into the server that is running earlier versions than 4.3.2.230207, then upgrade the server to 4.3.2.230207 or later versions and power cycle the server to recognize the adapter.

Utilities |
Note |
Always upgrade the BIOS, the Cisco IMC and CMC from the HUU ISO. Do not upgrade individual components (only BIOS or only Cisco IMC), since this could lead to unexpected behavior. If you choose to upgrade BIOS, and the Cisco IMC individually and not from the HUU ISO, make sure to upgrade both Cisco IMC, and BIOS to the same container release. If the BIOS and the Cisco IMC versions are from different container releases, it could result in unexpected behavior. Cisco recommends that you use the Update All option from the Host Upgrade Utility to update the firmware versions of Cisco IMC, BIOS, and all other server components (VIC, RAID Controllers, PCI devices, and LOM) together. |
Host Upgrade Utility
The Cisco Host Upgrade Utility (HUU) is a tool that upgrades the Cisco UCS C-Series firmware.
The image file for the firmware is embedded in the ISO. The utility displays a menu that allows you to choose which firmware components to upgrade. For more information on this utility, see http://www.cisco.com/en/US/products/ps10493/products_user_guide_list.html.
For details of firmware files in Cisco Host Upgrade Utility for individual releases, see Cisco UCS C-Series Integrated Management Controller Firmware Files, Release 4.3.
Updating the Firmware
Use the Host Upgrade Utility to upgrade the C-Series firmware. Host Upgrade Utility can upgrade the following software components:
-
BIOS
-
Cisco IMC
-
CMC
-
Cisco VIC Adapters
-
Broadcom Adapters
-
LAN on Motherboard
-
PCIe adapter firmware
-
HDD firmware
-
SAS Expander firmware
-
DCPMM Memory
-
PCI Gen5 retimer
All firmware should be upgraded together to ensure proper operation of your server.
Note |
We recommend that you use the select all and Update or Update & Activate All option from the Host Upgrade Utility to update the firmware versions of Cisco IMC, BIOS and all other server components (VIC, RAID Controllers, PCI devices, and LOM) together. Click Exit once you deploy the firmware. |
For more information on how to upgrade the firmware using the utility, see:
SNMP
The supported MIB definition for this release and later releases can be found at the following link:
Software Utilities

Cisco UCS servers has faulty drive notfications in Cisco IMC Web UI. If the data sanitization fails for any drives, then check the drive state. If the storage driver is in fault state, then the failure is expected. In some case, the storage drives might be in moderate fault. For those drives, data sanitization might pass in case the drive is visible to host. This issue is now resolved. |

Security Fixes in Release 4.3.4
Security Fixes in Release 4.3.4.240152
Defect ID - CSCwi59840
Cisco IMC includes Third-party Software that is affected by the vulnerabilities identified by the following Common Vulnerability and Exposures (CVE) IDs:
-
CVE-2023-48795—The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks, such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, also known as Terrapin attack.
This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and use of sequence numbers. For example, when there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC), the bypass occurs in chacha20-poly1305@openssh.com, (and if CBC is used, then the -etm@openssh.com MAC algorithms).
