Circuit configuration failure
When a tunnel cannot be created because the process for adding a new circuit configuration fails,
a FCIP Tunnel/Circuit Configurations dialog box displays. Using this dialog box, you can perform the
following tasks:
• Roll back the current changes to the circuit configuration.
• Elect to not roll back current circuit configuration changes.
• Continue configuring additional circuits at this point.
• Stop configuring additional circuits.
Configuring FCIP tunnel advanced settings
Compression, FCIP fast write and tape pipelining, IPSec and IKE policies, and FICON emulation
features are configured as advanced settings.
1. Click Advanced Settings on the Add FCIP Tunnel dialog box.
The Advanced Settings dialog box is displayed. This dialog box has a Transmission tab, Security
tab, and FICON Emulation tab.
2. Click OK to close Advanced Settings when you have configured the features that you want to
implement.
3. Click OK to close the Add FCIP Tunnel dialog box.
Enabling and disabling compression
Data compression can improve performance on long distance connections. The procedure for
enabling compression for the 4 Gbps Extension Switch and Blade is different than the procedure
for enabling compression for the 8 Gbps Extension Switch and Extension Blade.
For 4 Gbps Extension Switch and Blade:
1. Select Advanced Settings on the Add FCIP Tunnel dialog box to display the Advanced Settings
dialog box.
2. From the Transmission tab, select the Enable Compression check box to enable compression.
3. Click OK to commit your selection.
For the 8 Gbps Extension Switch and 8 Gbps Extension Blade:
1. Select Advanced Settings on the Add FCIP Tunnel dialog box to display the Advanced Settings
dialog box.
2. From the Transmission tab, select the Enable Compression check box to enable compression.
This enables the Compression Mode selector (Figure 291).
