Synchronizing the CFG mirror images with CFG images

A CFG mirror image is updated whenever a CFG flash synchronization occurs in the AU.

Agent Auto Unit Replacement

Use the enhancement to the Auto Unit Replacement functionality, known as the Agent Auto Unit
Replacement (AAUR), to ensure that all units in a stack have the same software image by
inspecting units joining a stack and downloading the stack software image to any unit that has a
dissimilar image. AAUR is enabled by default.
Agent Auto Unit Replacement functions in the following manner:
1. When a stand-alone switch joins an AAUR-enabled stack, the switch software image is
inspected.
2. If the switch software image differs from the stack software image, the AAUR functionality
downloads the stack software image to the joining unit.
3. The joining unit is then reset and becomes a member of the stack upon a restart.
