Important:
Restore a CFG image to a new unit happens only if you meet the following conditions.
• The AUR feature is enabled.
• At least one INACTIVE CFG mirror image exists in the stack.
• The MAC Address of the new unit is different from all the AMA of the INACTIVE CFG
mirror images in the stack.
The image restore process consists of the following steps.
Add a new unit to a stack:
For example, if you add a unit 5 (MAC Address 5) to the stack shown in
images in the stack after removing the BU (unit 1)
5: CFG mirror images in the stack after adding unit 5
• The INACTIVE CFG 1 mirror image is copied to the CFG 5 image. Unit5 now has the
configuration of unit 1, which is no longer in the stack.
• The INACTIVE CFG 1 mirror image in unit 2 becomes ACTIVE.
• The INACTIVE CFG 1 mirror image in unit 3 is removed.
• The MAC Address 5 of the unit 5 becomes the new AMA of the CFG1 mirror image.
Configuration — System
a. If more than one INACTIVE CFG mirror image is in the stack, select the one
with the smallest unit ID for restoration.
b. Send the INACTIVE CFG mirror image in the stack to the new unit. The
INACTIVE CFG mirror image becomes ACTIVE.
c. The new unit saves the received CFG image to the flash drive.
d. The new unit resets itself.
