Setting this write-only object to setcurrentCmem (1) or setalternateCmem (2) selects which flash bank's configuration memory the node will actually use; noOperation (100) does nothing. This is the configuration-memory counterpart to cdx6500ContFlashActiveImage, letting an admin switch which staged configuration set becomes active, typically alongside a corresponding image activation. For example, an admin rolling back a bad configuration change would set this to setalternateCmem to revert to the configuration saved in the alternate bank.
