Configuring Virtual Fabrics
17
3. Set up logical switches in each physical chassis:
a. Create logical switches in each physical chassis and assign ports to them. Make sure the
logical switches are configured to allow XISL use.
See “Creating a logical switch or base switch” on page 418 for instructions.
b. Disable all of the logical switches in each physical chassis.
Right-click each logical switch in the Connectivity Map or Product List and select
Enable/Disable > Disable.
c. Physically connect devices and ISLs to the ports on the logical switches.
You can connect ISLs from one logical switch to another logical switch in a different
physical chassis only if the two logical switches have the same FID (and are thus in the
same logical fabric). Traffic between these logical switches can travel over either this ISL or
the XISL in the base fabric. The physical ISL path is favored over the XISL path because it
has a lower cost.
d. Enable all logical switches in each chassis.
Right-click each logical switch in the Connectivity Map or Product List and select
Enable/Disable > Enable.
The logical fabric is formed.
Enabling Virtual Fabrics
For a list of platforms that are Virtual Fabrics-capable, refer to “Virtual Fabrics requirements” on
page 415.
ATTENTION
If the physical chassis is participating in a fabric, the affected fabric will be disrupted.
1. Select the physical chassis in the topology and click Configure > Virtual Fabric > Enable.
Alternatively, you can right-click the physical chassis and select Enable Virtual Fabric.
2. Read the warning message and click OK.
Disabling Virtual Fabrics
ATTENTION
Disabling Virtual Fabrics deletes all logical switches, returns port management to the physical
chassis, and reboots the physical chassis. If these logical switches are participating in a fabric, all
affected fabrics will be disrupted.
1. Select the physical chassis in the Chassis Group and click Configure > Virtual Fabric > Disable.
Alternatively, you can right-click the physical chassis in the Chassis Group and select Disable
Virtual Fabric.
2. Read the warning message and click OK.
