What is a Dual Flash Bank (DFB) device, and how does SWIM upgrade the device?
A. You can partition the Flash card into two equal banks. Each bank is a Flash partition. If you do not partition a Flash card, the Flash card is a Single Flash Bank (SFB), and the device is an SFB device. A device that has the Flash card divided into two partitions is a DFB device. Flash is partitioned into two banks: flash1 and flash2. You must store software image files in a single partition. The total size of a Flash partition limits the maximum size of a software image. On a DFB run-from-Flash (RFF) device, SWIM supports an upgrade of the Flash partition that does not contain the image that currently runs. SWIM cannot upgrade the RFF partition on DFB devices. SWIM cannot perform the upgrade because the other partition, which can be upgraded directly, is the recommended partition for the store of a new software image. The Cisco AS5200 device has two Flash cards: bootflash and flash. The flash is an RFF system and bootflash is a run-from-RAM (RFR) system. Bootflash stores bootldr im
