To do...
Save the boot file to the root
directory of the Flash of the master
device by using FTP, TFTP, or other
approaches.
Specify a boot file to be used at the
next boot of a member device or all
member devices of an IRF virtual
device
Reboot a member switch or all
member switches
CAUTION:
If the free Flash space on the member switch is not enough when you upgrade the boot file of an IRF
member switch, the system automatically compares the sum of the space occupied by the current boot file
and the remaining space with the size of the new boot file:
If the sum is greater than the size of the new boot file, the member switch automatically deletes the
•
current boot file to release the space.
• If the sum is smaller than the size of the new boot file, the member switch prompts you that the upgrade
fails.
Before upgrading the boot file of IRF member switches, make sure that the free Flash space of the member
switch is enough to store the new boot file.
