If a switchover occurs and switch 2 becomes the active virtual switch, the console becomes active on that
supervisor engine.
Interface Numbering
After conversion to a Virtual Switching System, the interface numbering changes from a traditional scheme:
<INTERFACE_TYPE> <MODULE>/<PORT>
To a new 3-number scheme:
<INTERFACE_TYPE> <SWITCH_ID>/<MODULE>/<PORT>
This new naming scheme allows a single configuration file to uniquely address the physical interfaces on both
chassis that are part of the same virtual switch domain.

File-System Naming
To facilitate the ability to uniquely identify multiple file systems on each supervisor engine or module across the
Cisco Virtual Switching System, a new role-independent file-system naming scheme has been implemented:
SW<SWITCH_ID>-SLOT<MODULE>-<FILESYSTEM>:
This naming scheme allows all unique file systems to be addressed and identified across the entire virtual switch
domain, regardless of supervisor-engine redundancy state:
vss#dir sw1-slot?
sw1-slot1-dfc-bootflash: sw1-slot5-const_nvram: sw1-slot5-disk0:
sw1-slot5-nvram: sw1-slot5-sup-bootdisk: sw1-slot5-sup-
bootflash:
sw1-slot7-dfc-bootflash: sw1-slot8-dfc-bootflash:
vss#dir sw2-slot?
sw2-slot1-dfc-bootflash: sw2-slot5-bootflash: sw2-slot5-
const_nvram:
sw2-slot5-disk0: sw2-slot5-nvram: sw2-slot5-sup-
