Upgrading IRF member switch boot file
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 up
rade
fails.
Before upgrading the boot file of IRF member switches, be sure that the free Flash space of the member
switch is enough to store the new boot file.
The system can automatically copy a boot file saved on the Flash of the master of an IRF virtual device to a
specified member switch or all member switches, and specify the boot file as the boot file to be used at the
next boot of the member switches. This feature simplifies the upgrade steps and improves management
efficiency.
To upgrade the boot file:
