Changes to Firmware Components:
- Following a link bounce event, there is a possibility that a link will fail to reach the Armed/Active state. The likelihood of this issue depends largely on the link type.
- In an SSH session, when typing (or pasting) commands, there is occasionally a 1-to-3 second delay in the echo of the command back to the terminal. The delay happens more frequently when the terminal has been idle, but occasionally happens on an active terminal.
- When Active Optical Cables (AOCs) are connected to externally-managed switches, links may come up at widths less than 4x.
- Very infrequently, when a link goes down, the logical link state can remain stuck in the 'Init' state.
- Cannot set default gateway for the IPv6 protocol in GUI.
- Chassis Viewer fails to display Daylight Saving Time (DST).
- Director Class: Verifying MM IP addresses has been updated and are no longer duplicated.
- When a link comes down, there is a possibility that the port—when it is next trying to come up—reports an illogical combination of states (e.g., the physical state is Config, but the logical state is Init), when it should be done. This combination can mislead fabric configuration software, that just looks at the logical state of a port.
- IPoIB does not work with IPv6 in Release 10.3.
- Due to high CPU utilization on the Management Module (MM) CPU, it has been observed that the Director Class switches may begin indicating thermal events. Customer network probing software may be associated with this high Management Module CPU utilization.
- It has been observed that the Director and Edge switch chassis can stop accepting new SSH CLI connections.
- On an Omni-Path Director chassis, it has been observed that the SSH/Telnet output of the CLI can slow down significantly over time.
- Software is not clearing PortRcvErrors.
- Director Class; cmured heartbeat issues.
- httpMimeAcceptEncoding can consume excessive CPU time.
- Director Switch Home page online help calls the Edge Switch help page.
- Logout button missing from Chassis Viewer Leaf Details screen.
- Need to create a Leaf FRU Information help file.
- Need to create a Spine-specific Main Status and Navigation help file.
- On an Omni-Path Director chassis, thermal events have been noted in some customer environments. The issue was related to high CPU demand on the master Management Module (MM), leading to starvation of the thermal management threads.
- On Director-class chassis that have redundant Management Modules (MM) running 10.2 firmware, messages may appear in the log indicating that files have failed to copy to the slave MM.
- A Leaf Module in Slot 114 not detected unless another Leaf is installed in Slot 113
- Director Class: The CLI and/or shell runs slow.
- Director Class: Retry fan tray I2C access errors.
Miscellaneous:
- Additional internal tracing is available to the firmware to improve link error-related diagnostic capabilities.
- In order to troubleshoot potential issues with externally-managed edge switches, Intel recommends that all fabrics contain at least one managed switch.
About Switch Firmware:
Given the large variety of models and different methods for upgrading the switch, if you wish to apply this package, we recommend that you read and understand the installation steps before you install a new firmware, even if you are a power user.
Usually the update procedure isn't much of a hassle as manufacturers try to make it as simple as possible; however, there are cases that are exceptions to this rule. First off, go to the system information page of the switch to check that the currently installed version isn't either newer or matching this release.
Applying a new firmware can decrease the security vulnerabilities, enhance overall performance and compatibility, improve various power management functions, resolve different errors, and add support for newly developed technologies and protocols.
It is recommended that you perform this step in a steady power environment such as the one ensured by a UPS unit, and that you don't interrupt the upgrade in any way, because this might cause the switch to malfunction.
That being said, click the download button, get and apply the new version, and check back with our website constantly to stay up to speed with the latest releases.
