The commands 'load sys config from-terminal verify' and 'load sys config file <filename> verify' causes loss of sync configuration and initiates a provisioning cycle. The 'verify' option on the 'load sys config' command is designed to ensure that a configuration (either from a file or pasted to the terminal) is valid, but not have it take effect.
The ConfigSync connection, including the connections to other devices, might be lost. In addition, provisioning might be impacted.
This affects the ConfigSync communication channel if configured.
You can avoid this issue by using the 'load sys config from-terminal verify' and 'load sys config file <filename> verify' commands 'merge' option, which keeps the current configuration during the validation step. Once affected by this issue, the workaround is to re-load the full configuration using the following command: tmsh load sys config partitions all.
Previously, the commands 'load sys config from-terminal verify' and 'load sys config file <filename> verify' did some operations related to sync and provisioning, though they are supposed to check only the validity of the configuration (without changing it). This has been resolved.
