Load and run a patch


Before loading a patch to a switch, upload the correct and valid patch package to the root directory (Flash:/) of the storage medium on the switch.

Method 1: Load and then run the patch.
patch load patch.pat all active //Load the patch in the system and then activate it.
patch run all //Run the patch.

Method 2: Load and run the patch simultaneously.
patch load patch.pat all run //Load and run the patch.
