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 and move the EX_ and
VEX_Ports to the base switch. The ports are then automatically enabled.
If you move existing EX_ or VEX_Ports to any logical switch other than the base switch, these
ports are automatically disabled.
If you want to change an EX_ or VEX_Port on the logical switch to be a non-EX 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.
