Uploading the Management Software from the Command Switch to
Member Switches
You may use enhanced stacking to install new releases of the
management software on the member switches from the command switch.
After you update the command switch with the new management software,
you can instruct it to upload the software to the member switches for you.
After you receive a new release of the management software and install it
on the command switch, as explained in “Downloading New Management
Software with TFTP” on page 463, you may use the UPLOAD IMAGE
REMOTELIST command to upload the software to the member switches
from the command switch. You may update specific member switches or
all of the switches. The format of the command is shown here:
upload image remotelist
The command, located in the Global Configuration mode, does not have
any parameters and displays this prompt:
Remote switches will reboot after load is complete...
Enter the list of switches ->
When you see this prompt, enter the enhanced stacking ID numbers of the
member switches to receive the management software from the command
switch. The numbers are viewed with the SHOW ESTACK REMOTELIST
command in the Privileged Exec mode. You may update the management
software on more than one member switch at a time. To specify more than
one switch, separate the numbers with commas. To update all of the
switches in the enhanced stack, enter ALL.
Here are the steps of the file transfer between the command switch and a
member switch:
1. The command switch sends its management software to the member
switch over the Ethernet link of the common VLAN that connects the
switches of the enhanced stack.
2. After the member switch receives the entire file, it compares the
version numbers of the new management software from the command
switch and its current software.
3. If the version numbers are the same, the switch cancels the update
and discards the file.
4. If the version numbers of the programs are different, the switch writes
the new management software from the command switch into its flash
memory. This phase may take up to one minute to complete.
5. After the file is written to flash memory, the member switch resets.
