Stacking Notes
Regarding steps 3, 4 and 5 above:
The “copy” command will take longer to complete with a stack of switches. This is due to the master
switch copying the software to the member switches. The master switch will display the line “Distributing
the code to the members of the stack!” for several minutes until the copy is done.
The “copy” command will copy the software to the non-active image on all the switches.
Examples:
If all switches in the stack have image1 as active, then the downloaded software will go to image2 on all
switches and a single “boot system image2” command will select image2 for the next active image on all
switches in the stack.

If the switches in the stack have some image1 active and some image2 active members, then the
downloaded software will go to the non-active image on each switch and multiple “boot system <unit>
imageX” commands will be required to select the next active image on each switch in the stack.
