Restoring a CFG image

Restoring a CFG image is a process that overwrites the CFG image of a new unit in a stack with an
INACTIVE mirror image stored in the stack.
Important:
Restore a CFG image to a new unit happens only if the following conditions are met.
• The AUR feature is enabled.
• The MAC Address of the new unit is different from the AMA of the INACTIVE CFG mirror
image corresponding to the replaced unit.
The image restore process consists of the following steps:
1. Adding a new unit to a stack
2. The INACTIVE CFG mirror image in the stack is sent to the new unit. The INACTIVE CFG
mirror image becomes ACTIVE.
3. The new unit saves the received CFG image to its flash.
4. The new unit resets itself.
For example, if a unit 5 (MAC Address 5) is added to the stack, the following occurs (see the figure
that follows):
• The INACTIVE CFG 1 mirror image is copied to the CFG 5 image. Unit 5 now has the
configuration of unit 1 that 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 CFG 1 mirror image.
