...

DRX's control commands are performed asynchronously. That is, the point at which the CLI control command is executed and returned is not the final completion of the state control. Therefore, after executing the control command, it is necessary to check whether the status has changed normally through the inquiry command.
- To determine if the state change has been completed, you must check the DRX events in real time after running the event notification command.
The drx-ctl command performs only one command at a time by default on the receiving drx server, which can cause a timeout for some queued commands if multiple commands are delivered simultaneously by DRX. To avoid timeouts, you need to ensure that the drx-ctl command is executed sequentially.
- The return value of drx-ctl is as follows.
  Command Return value Description
  Windows Linux
  drx-ctl
  
  0 0 success
  -1 255 failure
  -2 254 timeout
  -3 253 DRX not running (not working)
  -128 128 Invalid argument
  In Linux, the return value is limited to 0-255, so negative values are represented by adding 256.

4. Operation

DRX configures the resource information into a file and controls each resource with the drx-ctl command.

...

drx-ctl version

Option alias : ver
Print version information of DRX.

drx-ctl dump [res|all]
