FC-FC routing and Virtual Fabrics
If Virtual Fabrics is not enabled, FC-FC routing behavior is unchanged. If Virtual Fabrics is enabled,
then in the FC-FC routing context, a base switch is like a backbone switch and a base fabric is like a
backbone fabric.
If Virtual Fabrics is enabled, the following rules apply:
• EX_Ports and VEX_Ports can be configured only on the base switch.
When you enable Virtual Fabrics, the chassis is automatically rebooted. When the switch comes up,
only one default logical switch is present, with the default fabric ID (FID) of 128. All previously
configured EX_Ports and VEX_Ports are persistently disabled with the reason "ExPort in non base
switch". You must explicitly create a base switch, move the EX_Ports and VEX_Ports to the base
switch, and then enable the ports.
If you move existing EX_Ports or VEX_Ports to any logical switch other than the base switch, these
ports are automatically disabled.
If you want to change an EX_Port or VEX_Port on the logical switch to be a non-EX_Port or
VEX_Port, you must use the portCfgDefault command. You cannot use the portCfgExPort
command because that command is allowed only on the base switch.
• EX_Ports can connect to a logical switch that is in the same chassis or a different chassis. However,
the FID of the EX_Port must be set to a different value than the FID of the logical switch to which it
connects.
• EX_Ports and VEX_Ports -- those in FC routers and those in a base switch -- cannot connect to any
edge fabric with logical switches configured to use XISLs.
If you connect an EX_Port or VEX_Port to an edge fabric, you must ensure that there are no logical
switches with XISL use enabled in that edge fabric. If any logical switch in the edge fabric allows
XISL use, then the EX_Port or VEX_Port is disabled. Refer to
Configuring a logical switch for XISL
use on page 293 for instructions on disallowing XISL use.
