Changes:
- In links exhibiting a high error rate, a rare PortRcvError is possible, resulting in a link down event. Such links should retrain and return to operation without user interaction. In cases where the Link Quality is less than or equal to 3, the interconnect in the link should be evaluated for possible replacement to prevent future PortRcvErrors from occurring.
- HFI links may occasionally take several minutes to reach link up.
- When links containing AOCs are coming up, there can be an immediate link width downgrade within 30-60 seconds of link up. The downgrade can often be addressed by bouncing the port. If the downgrade recurs (or the link quality of the link is less than or equal to 3), the interconnect should be evaluated for possible replacement.
- Director Class Switches: The Chassis Viewer Module Details page does not display properly on Firefox and Chrome.
- Use CLI command(s) to set the OOB LAN IP when DHCP is enabled.
- Use CLI command(s) to set the OOB LAN IP address.
- Edge Switches: Chassis Viewer reports incorrect part numbers for supplies and fans
- When using opagenchassis to view updated IP address(es), the response is delayed.
- An internal I2C error may result in a Director leaf reinitializing (momentarily going off-line), which may disrupt fabric operation. In Release, the switch firmware now handles I2C errors such that leaf operation is not impacted.
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.
