Brocade Fabric OS Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 286)

NOTE
If you want to use Admin Domains in a fabric, you must first disable VF mode.
1. Connect to the physical chassis and log in using an account with the chassis-role permission.
2. Use the fosConfig command to check whether VF mode is disabled:
fosconfig --show
3. Move all ports to the default logical switch.
lscfg --config 128 -slot slot -port port
4. Delete all of the non-default logical switches.
lscfg --delete fabricID
5. Use the fosConfig command to disable VF mode:
fosconfig --disable vf
6. Enter y at the prompt.
The following example checks whether VF mode is enabled or disabled and
then disables it.
switchA:FID128:admin> fosconfig --show
FC Routing service: disabled
iSCSI service: Service not supported on this Platform
iSNS client service: Service not supported on this Platform
Virtual Fabric: enabled
Ethernet Switch Service Service not supported on this Platform
switch:admin> fosconfig --disable vf

Configuring logical switches to use basic configuration values
All switches in the fabric are configured to use the same basic configuration values. When you create
logical switches, the logical switches might have different configuration values than the default logical
switch. Use the following procedure to ensure that newly created logical switches have the same basic
configuration values as the default logical switch.
NOTE
For most users, you do not need to run this procedure. Contact your switch service provider to
determine if you need to use this procedure.
You need to run this procedure only once on each chassis, after you enable Virtual Fabrics but before
you create logical switches. The configuration settings are then preserved across reboots and
firmware upgrades and downgrades.
Use the following procedure to configure logical switches to use basic configuration values:
