•
For the 4 Gbps Extension Switch and Blade and the 8 Gbps Extension Blade, the key value
must be between 12 and 32 alphanumeric characters. The length depends on the chosen
IKE policy.
•
For the 8Gbps Extension switch, the key value must be a minimum of 32 alphanumeric
characters.
These policies are used to make the connection more secure through authentication and
encryption. When you select a policy for the local switch, a matching policy is automatically
selected on the remote switch. If no matching policy is found, you must manually configure the
policy on the remote switch.
7. 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).
Configuring FICON emulation
FICON emulation and acceleration features and operating parameters are configured from the
FICON Emulation tab (
Figure 352 ). Before you configure these features you must decide which
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.
1. Select Advanced Settings on the Add FCIP Tunnel or Edit FCIP Tunnel dialog box to display the
Advanced Settings dialog box.
2. Select the FICON Emulation tab.
