Configuring FICON emulation

FICON Emulation tab
features you want to implement, and you must look closely at the operational parameters to
determine if values other than the default values are better for your installation.

2. Select the FICON Emulation tab.
3. Select the check boxes for the FICON emulation features you want to implement.

You can activate the Enable backward compatibility feature on 8 Gbps platforms if IPSec is
enabled. This allows multiple 1 Gbps circuits to be created using 10 Gbps ports even if the
switch at one end of the tunnel is using Fabric OS 7.0 and the switch at the other end is using
Fabric OS earlier than v7.0. Note that this feature can only be enabled when IPSec is enabled
and when circuits are configured without any advanced 10 Gbps features, such as lossless
failover, multi-gigabit circuits, or 10 Gbps Adaptive Rate Limiting (ARL).
(Figure 293). Before you configure these features you must decide which
dialog box.
