Adding an FCIP circuit

9. Select values for bandwidth settings. An uncommitted bandwidth is not allowed on an FCIP
circuit. You must select Committed bandwidth. If you want to use ARL, set Minimum and
Maximum bandwidth values. Bandwidth grows towards the maximum and reduces towards the
minimum based on traffic conditions. If you do not want to use ARL, set Minimum and
Maximum to the same value to set a single committed bandwidth. Refer to
“Adaptive Rate
Limiting” on page 765 for more information about ARL.
NOTE
The committed value range in the Add FCIP Circuit dialog box depends on the extension switch
or blade platform.
10. If the physical connection exists, click Verify IP Connectivity to test the connection between
switch one and switch two. The IP connectivity of the connection is tested with the ping utility.
11. Select Advanced Settings from the Add FCIP Circuit dialog box and continue if you want to do
any of the following:
•
Disable selective acknowledgement if your system cannot support selective
acknowledgement.
•
Set the keep alive timeout to a value other than the default of 10 seconds.
•
Set the minimum retransmission time to a value other than the default of 100 ms.
•
Set the maximum retransmits to a value other than the default.
•
Use TCP/IP DSCP or L2CoS to prioritize FC traffic.
If you select Advanced Settings, the Transmission tab of the FCIP Circuit Advanced Settings
dialog box displays (
