Fixed customer issues
| Case number | Description |
|---|---|
| 02152689 02153384 02173302 02163940 02157242 02157534 02178034 02177033 | KCT NG now correctly negotiates SSH key exchange algorithms, resolving connection failures during session establishment to specific devices. |
| 02153384 | KCT NG now successfully captures and saves complete backup configurations for Dell OS10 SmartFabric devices, correctly handling output pagination and "--more--" prompts during retrieval. |
| 02157534 02173365 | KCT NG now ignores timestamp-only changes in device configurations. This prevents false configuration change for certain device types and aligns with KCT Legacy functionality. |
| 02161457 | ZIP creation no longer fails with "The file already exists" after successful deletion of ConfigChanges.zip in customer environment. |
| 02157225 02173365 | A consolidated report mail and error mail are now generated and sent, similar to the behavior in the KCT Legacy environment. Individual device-level emails are no longer sent for this activity. |
| 02157534 02157225 02173365 | Email notifications are generated for configuration changes detected through activities such as device.backup.running.config, device.TFTP.backup, device.compare.two.files, and device.compare.startup.running. Email notifications are no longer sent when no configuration changes are identified. If an error occurs during any of these activities, an error notification email is automatically triggered and sent. |
| 02157225 02173365 | FileCompareChanges.zip now contains the generated file comparison report/details of detected changes between the compared files. |
| 02157225 02173365 | CommandOutput.zip file now contains the generated command output file(s) from the Send.CLI activity, and users can access command execution results from the email attachment. |
| 02157225 02173365 | Email attachment behavior now matches that of KCT Legacy. Unnecessary configuration backup attachments are not included. The text report attachment is correctly generated and attached to the email. |
| 02157225 02173365 | There is no longer any functional difference between KCT Legacy and KCT NG for TFTP backup report generation. A report email is sent only when configuration changes are detected, and an error email is sent when there is an issue connecting to the device or while fetching the configuration from the device. |
| 02157225 02173365 | Consistent with KCT Legacy behavior, whenever a report email and/or error email is sent from KCT NG, the corresponding details are printed in the InfoLog. |
| 02165097 | TFTP backup validation in KCT NG has been improved to support multiple valid file paths and naming conventions, aligning behavior with KCT Legacy. |
