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:
1. Connect to the physical chassis and log in using an account with the chassis-role permission.
2. Enter the configureChassis command to ensure that newly created logical switches have the same basic configuration values
as the default logical switch:
configurechassis
3. Enter n at the prompts to configure system and cfgload attributes. Enter y at the prompt to configure custom attributes.
System (yes, y, no, n): [no] n
cfgload attributes (yes, y, no, n): [no] n
Custom attributes (yes, y, no, n): [no] y
4. Enter the appropriate value at the Config Index prompt. Contact your switch service provider to determine the appropriate
value.
Config Index (0 to ignore): (0..1000) [3]:
Creating a logical switch or base switch
When a logical switch is created, it is automatically enabled and is empty--that is, it does not have any ports. After creating the logical
switch, you must disable the switch to configure it and set the domain ID. You then assign ports to the logical switch.
You can optionally define the logical switch to be a base switch. Each chassis can have only one base switch.
NOTE
Domain ID conflicts are detected before fabric ID conflicts. If you have both a domain ID conflict and a fabric ID conflict, only
the domain ID conflict is reported.
