downloading files in Performing File Operations by Using FTP Commands.

Procedure

Step 1 Enter the user view.

Step 2 Run:

patch load patchname all run

NOTE

l The patch load patchname all run command can activate only one patch file each time.

patchB.pat is activated when the system is running the earlier version patchA.pat, patchB.pat takes

effect. To run patchA.pat again, run the patch delete all command to delete patches in the system,

and load and activate patchA.pat. Alternatively, run the startup patch command to specify

patchA.pat as the next startup patch, and then restart the device to make patchA.pat effective.
