| Skylight sensor: control | sensor control-1000 | VCX_22.12.1 | VCX_22.12.1_25331.afl |
Note: This firmware release includes the images needed to deploy the Skylight sensor: control using a KVM or VMware Hypervisor, as well as the .afl upgrade file that is typically part of a Skylight sensor: control release.
Skylight sensor: control 22.12.1 requires Skylight orchestrator 20.05 as its minimum. Customers using SD Vision must first upgrade to Skylight orchestrator 20.05 before upgrading to Skylight sensor: control 20.05.
Important Notes
Skylight sensor: control upgrades
In Skylight sensor: control 22.12.1, any module upgrades from firmware versions previous to VCX 2.2 FWSuite (FWSUITE_VCX_2.2_10190) have been blocked, in order to protect against a potential complete loss of connectivity/functionality that cannot be recovered. In order to upgrade a module from an older FWSuite version, an older version of Skylight sensor: control must be used to first upgrade the module to FWSUITE_VCX_2.2_10190:

Skylight sensor: control upgrade consideration
Upgrading the Skylight sensor: control firmware version does not automatically upgrade the module firmware suite.
As of Skylight sensor: control 22.12, you can use modules that have older firmware suite versions with the current release. For Skylight sensor: control 22.12, the supported module firmware suite starts with version 19.12.
CAUTION: The upgrade process was hardened in VCX 2.7. Under specific circumstance the module upgrade can still fail. This happens if the module management is lost and the module performs an automatic rollback. The module can brick if the power is lost in a critical short time period. This was seen in a lab environment only and never reported by a customer.
Before doing the upgrade, it is recommended to enable Extra Reconnection Delay with the previous release (refer to the Skylight sensor: control User Manual, section 4.3, “Adding Remote Devices” for more details on how to enable Extra Reconnection Delay).
The downgrade is still executed using the previous software that still has the update process deficiencies. The downgrade can still cause remote devices to fail and should be avoided at the exception of VCX 2.5.0.2 and VCX 2.6.0.1 for which the downgrade is supported without issue.
It is not recommended to change any other module configuration when operating with a different firmware version. Changing the configuration could result in unknown behavior. A factory reset using AMD could be required in some cases. In a future release, the Skylight sensor: control software will prevent changing configuration for modules running a different firmware version.
For cases where all modules cannot be upgraded at the same time, it is recommended to run different Skylight sensor: control instances with different software versions. Modules to be upgraded should be moved between Skylight sensor: controls.
When downgrading Skylight sensor: control software, the modules firmware version shall also be downgraded. The downgrade process shall follow these steps in order to successfully downgrade Skylight sensor: control software and modules firmware. Note that downgrades are not recommended (see CAUTION above).
CAUTION: The downgrade is still executed using the previous software that still has the update process deficiencies. The downgrade can still cause remote devices to fail and should be avoided.
Before doing the downgrade, it is recommended to enable Extra Reconnection Delay with the previous release (refer to the Skylight sensor: control User Manual, section 4.3, “Adding Remote Devices” for more details on how to enable Extra Reconnection Delay).
Scenario 1: downgrade using Skylight sensor: control rollback
- The modules firmware must be downgraded first using the newest Skylight sensor: control software.
- Perform Skylight sensor: control rollback.
Scenario 2: downgrade using a different Skylight sensor: control instance
- The modules firmware must be downgraded first using the newest Skylight sensor: control software.
- Delete modules from the newest Skylight sensor: control instance.
- Discover the modules using the older Skylight sensor: control instances.
Firmware Version 22.12.1_25331 (2023-04-06)
New Features and Enhancements
None.
Addressed Issues
The following issues have been corrected in this release:
TWAMP session remains in an error state after an interruption
The TWAMP session with TWAMP control remains in an error state after a network interruption.
This issue has been fixed.
10G SFP module failed to connect to Skylight sensor: control
The 10G SFP module fails to connect to the Skylight sensor: control after upgrading the module firmware suite. The A2h diagnostic information is not aligned with the force link up feature.
This issue has been fixed.
Memory leak when running the configuration export command
Running the configuration export command every minute causes the SessionMgr process size to increase to around 2% each day.
This issue has been fixed.
