Enabling Virtual Fabrics On A Discovered Device - Brocade Communications Systems Brocade BladeSystem 4/24 User Manual

19
This procedure describes the general steps you take to enable the Virtual Fabrics feature and
configure logical fabrics. The logical fabrics in this example span multiple physical chassis, and the
logical switches in each fabric communicate using an XISL in the base fabric.
1. Enable Virtual Fabrics in each physical chassis.
2. Set up base switches in each physical chassis:
3. Set up logical switches in each physical chassis:

Enabling Virtual Fabrics on a discovered device

ATTENTION
Enabling Virtual Fabrics is disruptive. You should disable the physical chassis before you enable
Virtual Fabrics.
ATTENTION
If the physical chassis is participating in a fabric, the affected fabric will be disrupted.

See "Enabling Virtual Fabrics on a discovered device"
a. Create base switches in each physical chassis and assign ports to them.
See "Creating a logical switch or base switch"
b. Disable the base switches in each physical chassis.
Right-click each base switch in the Connectivity Map or Product List and select
Enable/Disable > Disable.
c. Physically connect ports in the base switches to form XISLs.
d. Enable all of the base switches. This forms the base fabric.
Right-click each base switch in the Connectivity Map or Product List and select
Enable/Disable > Enable.
a. Create logical switches in each physical chassis and assign ports to them. Make sure the
logical switches are configured to allow XISL use (this is the default).
See "Creating a logical switch or base switch"
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.
