Virtual Fabrics interaction with Fabric OS features
Virtual Fabrics interaction
Virtual Fabrics and Admin Domains are mutually exclusive and are not supported at the
same time on a switch. To use Admin Domains, you must first disable Virtual Fabrics; to
use Virtual Fabrics, you must first delete all Admin Domains.
See "Deleting all user-defined Admin Domains non-disruptively"
information on deleting Admin Domains without disrupting device-to-device
communication.
Virtual Fabrics uses a configuration file that is different from the configuration file used
to download system configuration parameters. See
Configuration File,"
configuration file.
Encryption functionality using the FS8-18 blade is available only on the default logical
switch.
All EX_Ports must reside in a base switch.
You cannot attach EX_Ports to a logical switch that has XISL use enabled. You must use
ISLs to connect the logical switches in an edge fabric.
Only 8-Gbps ports are allowed to be used as FC router EX_Ports, with the exception of
VEX_Ports on the FR4-18i blade.
See Chapter 21, "Using the FC-FC Routing Service,"
Fabrics and FC-FC routing.
Up to two logical switches per chassis can run FICON Management Server (CUP), but the
FICON logical switch must use ISLs and not XISLs.
In interoperability modes 2 and 3, you cannot use XISL in the logical fabric. The logical
switches must be connected only with ISLs.
Licenses are applicable for all logical switches in a chassis.
Performance monitors are supported in a limited number of logical switches, depending
on the platform type. See
information about performance monitoring when Virtual Fabrics are enabled.
Port mirroring is not supported when Virtual Fabrics is enabled.
QoS VCs are maintained across the base fabric. See
Behavior," for more information about using the Adaptive Networking features with
Virtual Fabrics.
Traffic Isolation zones with failover disabled are not supported in logical fabrics. See
Chapter 18, "Optimizing Fabric Behavior,"
Zones with Virtual Fabrics.
