Overview

Cisco Intersight Infrastructure Services (IIS) enable the streamlined deployment, monitoring, management, and support of physical and virtual infrastructure. IIS supports Cisco Unified Computing System™ (UCS) servers and third-party devices. In addition, IIS provides the following advanced management and support capabilities along with global visibility of infrastructure health and status.

  • Telemetry data can be analyzed without any manual intervention when a problem occurs.

  • Service Request (SR) and a Return Material Authorization (RMA) are raised automatically.

Intersight Managed Mode (IMM) is a new IIS architecture that manages the UCS Fabric Interconnected systems through a Redfish-based standard model. IMM unifies the capabilities of the UCS Systems and the cloud-based flexibility of Intersight, thus unifying the management experience for the standalone and Fabric Interconnect attached systems.

Security Fixes

Security Fixes in Release 4.3(5.240032)

Defect ID - CSCwk78644

Cisco UCS 6400 Series Fabric Interconnects and UCS 6500 Series Fabric Interconnects includes third-party software that is affected by the vulnerabilities identified by the following Common Vulnerability and Exposure (CVE) ID:

Remote Unauthenticated Code Execution Vulnerability in OpenSSH Server

CVE-2024-6387—A race condition has been identified in the sshd service related to its signal handler. If a client fails to authenticate within the LoginGraceTime period (default is 120 seconds, previously 600 seconds in older OpenSSH versions), the sshd SIGALRM handler is triggered asynchronously. This handler, however, invokes several functions that are not safe to call from within a signal handler, such as syslog().

The affected third-party software component has been upgraded to a version that includes fixes for the vulnerability. Future versions of the product(s) will not be affected by this vulnerability.

Security Fixes in Release 4.3(4.240066)

Defect ID - CSCwj35846

Defect ID

Description

First Bundle Affected

CSCwk28221

When changing the FCoE VLAN from 3121 to 3120 in Cisco UCS Manager while FI is in FC Switch mode, initiators can FLOGI and obtain FCID but fail to PLOGI to target ports, resulting in indefinite timeouts. Admin down/up of the FC link or port-channel resolves the issue. This change causes path loss in ESXi, with host logs showing successful FLOGI and FCID assignment but PLOGI timeouts.

4.3(2b)

CSCwk29071

On Cisco UCS-FI-6332-16UP FI running release 4.1(3j), the Transmit Fault Count increases by 3 when executing the show interface transceiver details command or generating tech support logs. This issue is observed on Fabric Interconnects (FI-A and FI-B) equipped with Cisco FINISAR SFP modules (DS-SFP-FC16G-SW) but does not occur with Cisco AVAGO SFP modules. The increment is specific to Cisco FINISAR SFP modules and does not indicate any hardware errors.

4.1(3j)A

CSCwk49974

Cisco UCS-FI-6454 Fabric Interconnects Cisco UCS Manager release 4.3(4a) experience unexpected reboots when performing SNMP bulkwalkget requests with packet sizes greater than the MTU (1500). This issue is due to SNMP jumbo packet fragmentation, leading to kernel panics and high impact on data traffic if failover is not configured.

4.3(3a)A

CSCwk09092

During an upgrade of Cisco UCS Manager from 4.2(3g) to 4.3(3a) on Cisco UCS-FI-6454 Fabric Interconnects in UCS Manager Cluster mode, the Data Management Engine (DME) consumes 100% of FI CPU resources, leading to significant slowness. This results in the DME being inaccessible and unable to use scope commands. The Cisco UCS Manager GUI becomes inaccessible, CLI logins take excessive time and often fall to the default role regardless of the account, and changes in Cisco UCS Manager cannot be made. The issue persists through failover, pmon stop/start, and container restarts.

4.3(3a)A

CSCwk66102

After upgrading Cisco UCS Manager from 4.3(2e)A to 4.3(3c)A on Cisco UCSX-FI-6536 Fabric Interconnects, the Communication Service FSM fails with the following error:

[FSM:FAILED]:

communication service configuration

(FSM:sam:dme:CommSvcEpUpdateSvcEp).

Remote-Invocation-Error:

name to naming property('snmpCommSecP.name')

mismatch: Rn:

'[SNMP String]',

Prop:'SNMP

String'

This issue occurs despite the SNMP string being correctly set. The failure may impact LDAP authentication if FQDN is used for the LDAP server(s) due to DNS not being programmed when the FSM fails.

4.3(3c)A

CSCwm02504

When updating the UBM firmware on Cisco UCS X210c M6 servers with UCSX-X10C-RAIDF, the update may fail with the following error:

Error: Failed to get product serial number

This results in the UBM getting stuck in an activating state, which can be observed under the installed firmware tab by expanding the RAID controller. This issue is typically found in IMM-based firmwares, as no UCS Manager firmwares have featured a 0x42e UBM firmware.

CSCwm70985

During or immediately after a firmware upgrade/downgrade on NVIDIA L40s GPUs, no read/write operations should be performed on the card. However, PNUOS performs read operations using the nvidia-smi utility to check the GPU mode immediately after the upgrade. This issue occurs when upgrading/downgrading firmware on NVIDIA L40 GPUs, causing PNUOS to crash and raise a major fault.

You can perform mode changes using NVIDIA tools on the host OS if required. This limitation does not affect other L-series GPUs, which continue to support mode changes.

 Workaround

First Bundle Affected

CSCwm09720

In Cisco UCS Manager releases 4.3(3) and 4.3(4), the MC Server generates a high volume of delta events in Cisco UCS X9508 chassis, causing a flood of events to Cisco bladeAG. This results in continuous Cisco bladeAG crashes, preventing blade discovery and user SP operations. The issue is due to the mc_delta_psu_fw_version function incorrectly setting the "used" length, generating unnecessary 256KB delta events. Initializing the "used" length to 0 prevents these delta events.

As a workaround, increase the virtual memory limit of bladeAG to 800MB.

4.3(3c)C

CSCwk82692

In Cisco UCS Manager releases 4.3(3a) through 4.3(4b) on Cisco UCS 6454/64108/6536 Fabric Interconnects, bladeAG processes may reach the 400MB memory limit and crash due to memory aborts. This results in blades being stuck in a consistent discovery loop.

The bladeAG service experience multiple restarts, causing users to be unable to perform blade operations such as power on/off and complete discovery until the process stabilizes. This issue is observed in domains with a minimum of 16+ Cisco UCS X-Series chassis.

As a workaround, increase the virtual memory limit of bladeAG to 800MB.

Workaround

First Bundle Affected

CSCwj68704

In the Cisco UCS X-Series Direct configuration, using QSFP-100G-AOC7M/25M/30M or QSFP-100G-SR4-S transceivers to connect to an IXIA device results in an unstable connection with persistent link flapping.

As a workaround, switch to using a 40G or 10G connection when the SPAN (Switched Port Analyzer) destination port is connected to an IXIA device.

4.3(4.240078)

CSCwk80589

In Cisco UCS X-Series Direct, the X-Series compute node shows missing GPU information after the chassis is power-cycled.

In a Cisco UCS X-Series Direct system with X-Series compute nodes containing the Cisco UCS X440p PCIe node, when the chassis is powered off and then powered back on, and the server power remains off (which occurs if the server is not associated with any profile), the GPU inventory shows the FRU details as empty.

As a workaround, perform a rediscovery of the affected server.

4.3(4.240078)

CSCwk44340

When a Cisco UCS X-Series Direct system overheats, a 'Missing' alarm is raised on all the compute nodes. Even after the system recovers, the servers are not re-discovered. As a result, the alarms do not get cleared until the blade is removed or the Cisco IMC reconnects.

As a workaround, reboot the Cisco IMC.

4.3(4.240078)

CSCwk69678

For Cisco UCS X-Series Direct, Out-of-Band virtual KVM sessions are not getting launched from Intersight. If the Out-of-Band IP address is configured and the device connector firmware is upgraded, the IP filtering rules are retained in both the Fabric Interconnects, causing Out-of-Band IP address to stop working.

As a workaround, deploy the Server Profile after the device connector upgrade.

4.3(4.240078)

CSCwk73957

In Cisco UCS X-Series Direct, the primary Fabric Interconnect does not reboot immediately upon erasing the inadb; it waits for the secondary Fabric Interconnect to come online.

There is no known workaround.

 4.3(4.240078)

CSCwi92005
