This topic describes how to change a vSwitch to resolve the issue that a job fails to be started because the number of IP addresses of the vSwitch is insufficient.


After you change the vSwitch, you need to add the CIDR block of the new vSwitch to the whitelist of the storage system that fully managed Flink needs to access.


  1. Log on to the Realtime Compute for Apache Flink console.
  2. Click the Fully Managed Flink tab.
  3. Find the desired workspace and choose More > Modify vSwitches in the Actions column. Add a vSwitch
  4. In the Modify vSwitches dialog box, select the vSwitch that you want to add. Add a vSwitch
    Note If the vSwitch list does not include the required vSwitch, click Create vSwitch in the note at the top of the list. After you create a vSwitch on the Create vSwitch page, refresh the Modify vSwitches dialog box and select the new vSwitch.
  5. Click OK.
