Configuring Virtual Fabrics
17
Creating a logical switch or base switch
NOTE
Virtual Fabrics must be enabled on at least one physical chassis in your fabric.
Optionally, you can define the logical switch to be a base switch. Each chassis can have only one
base switch.
1. Select a switch with Virtual Fabrics enabled on the Product List or Connectivity Map and select
Configure > Virtual Fabric > Logical Switches.
The Logical Switches dialog box displays.
2. Select the physical chassis from which you want to create a logical switch in the Chassis list.
3. Select one of the following in the Existing Logical Switches table:
• A physical chassis in the Discovered Logical Switches node.
• A NewFabric logical switch template in the Discovered Logical Switches node.
• The Undiscovered Logical Switches node.
If you select a logical switch template, the fabric-wide settings for the logical switch are
obtained from the settings in the template.
If you select a physical chassis or the Undiscovered Logical Switches node, the fabric-wide
settings for the logical switch are the default settings.
4. Click New Switch.
The New Logical Switch dialog box displays.
5. Click the Fabric tab, if necessary.
6. Enter a fabric identifier in the Logical Fabric ID field.
This assigns the new logical switch to a logical fabric.
If the logical fabric does not exist, this creates a new logical fabric as well as assigning the new
logical switch.
7. (Optional) Select the Base Fabric for Transport check box if you want to configure the switch to
use XISLs.
In the following cases, you should make sure the Base Fabric for Transport check box is
cleared, because XISL use is not supported:
• FICON logical fabrics
• Logical switches in an edge fabric connected to an FC router
• Logical switch in InteropMode 2 or InteropMode 3
• Logical switch has VE_Ports and is running Fabric OS 6.4.x or earlier.
NOTE
For switches running Fabric OS 7.0.0 or later, VE_Ports on the 8 Gbps Extension Blade are
supported on logical switches that use XISLs.
