6. If a VLAN ID is used to route frames between the switches over the physical connection, enter
the VLAN ID under Switch One Settings. The same VLAN ID is automatically assigned to switch
two.
7. Select values for bandwidth settings. An uncommitted bandwidth is not allowed on an FCIP
circuit. You must select Committed bandwdith, and set Minimum and Maximum bandwidth
values. Bandwidth grows towards the maximum and reduces towards the minimum based on
traffic conditions.
8. 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.
9. Select Advanced Settings and continue with “Configuring FCIP Circuit Advanced Settings” if you
want to do any of the following.:
• Turn selective acknowledgement off.
• Use the circuit as a failover circuit.
• 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.
Configuring FCIP Circuit Advanced Settings
If you select Advanced Settings, the Transmission tab of the FCIP Circuit Advanced Settings
dialog box displays.
- Select the Selective Ack Off check box to disable selective acknowledgement. Selective
acknowledgement is desirable, but some systems may have a requirement to disable
selective acknowledgement.
- The Metric option is used to identify a failover circuit. By assigning a non-zero metric (1),
you identify the circuit as a failover circuit. By default, a circuit is assigned a metric of 0. If
a circuit fails, FCIP trunking tries first to retransmit any pending send traffic over another
circuit with a metric of 0. If no circuits with a metric of 0 are available, then the pending
send traffic is retransmitted over any available circuit with a metric of 1.
- Use the Keep Alive Time Out (ms) option to override the default value of 10000 ms. As
shown, the range is from 8000 to 7200000.
- Use the Max. Retransmission Time (ms) option to override the default value of 100 ms.
- Use Max. Retransmits option to override the default value of 8. As shown, the range is 1 to
8.
10. Click Finish to close the FCIP Tunnel Configuration wizard.
