(Optional) Performing ISSU Precheck

(Optional) Performing ISSU Precheck


Before an ISSU upgrade, you can run the issu precheck command to perform ISSU precheck, including checking the ISSU modes supported by service modules.

ISSU precheck has little impact on the system and does not cause the standby MPU to restart. Therefore, you can perform ISSU precheck at any time except when ISSU is running.


  1. Run the issu precheck system-software system-file command in the user view to perform ISSU precheck.
