Description (partial)

In a 3-node cluster of Gen-2 Cisco DNA Center appliances (Cisco part number DN2-HW-APL-XL) version, while running the Maglev wizard, 8 interfaces can be seen where the first 4 interfaces are from the DA4 adapter which is enabled from the CIMC side. All the following interfaces have no configuration.

Once the DA4 adapter is disabled from the CIMC side, (under Compute > BIOS > I/O) 8 interfaces are seen again on the maglev side, but this time first 4 interfaces are duplicate entries for those from the DA2 adapter, with a blank configuration.
