Creating a logical switch or base switch
21
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) Clear the Base Fabric for Transport check box to configure the switch to not use
XISLs.
By default, the logical switch is configured to use XISLs; however, you should clear the Base
Fabric for Transport check box, because XISL use is not supported in the following cases:
• FICON logical fabrics
• Logical switches in an edge fabric connected to an FC router
• Logical switch in InteropMode 2 or InteropMode 3
• VE_Ports of the 8 Gbps 12-FC port, 10 GbE ports, 2 - 10 GbE ports Extension Blade are to
be added to the logical switch
8. (Optional) Perform the following steps to make the logical switch a base switch:
a. Clear the Base Fabric for Transport check box.
This check box is not relevant for base switches because all base switches can use XISLs.
b. Select the Base Switch check box.
9. (Optional) For Backbone Chassis only, select an option in the 256 Area Limit list to use
256-area addressing mode (zero-based or port-based) or to disable this mode (default).
The 256-area addressing mode can be used in FICON environments, which have strict
requirements for 8-bit area FC addresses.
10. (Optional) Enter new values for the fabric-wide parameters or leave unchanged to accept the
current values.
Click the Help button for detailed information on each parameter.
11. Click the Switch tab.
12. Enter a name for the logical switch in the Name field.
