Configuration steps

Creating additional FCIP circuits
If the Advanced Extension (FTR_AE) license is enabled, additional FCIP circuits can be created and
added to an FCIP tunnel (VE_Port) using the portCfg fcipcircuit create command. The following
examples add a circuit to the tunnel in the basic sample configuration (refer to Figure 12 on
page 43).
The following command creates circuit 1 on the FX8-24 end of the tunnel.
switch:admin> portcfg fcipcircuit 8/12 create 1 192.168.11.79 192.168.1.25 -b
15500 -B 62000
The following command displays configuration details for circuit 1.
portshow fcipcircuit 8/12 1
The following command creates circuit 1 on the 7800 switch end of the tunnel.
switch:admin> portcfg fcipcircuit 16 create 1 192.168.1.25 192.168.11.79 -b 15500
-B 62000
The following command displays configuration details for circuit 1.
portshow fcipcircuit 1
Note the following:
• The VE_Ports used to create the tunnel are the same as specified on the FCIP tunnel in the
basic sample configuration. The VE_Ports uniquely identify the tunnel, and the circuit is
associated with this specific tunnel.
• The unique destination and source IP addresses are mirrored on either end of the tunnel. The
address 192.168.11.79 is the destination address for the FX8-24 blade, and the source
address for the 7800 switch, while the address 192.168.1.25 is the destination address for
the 7800 switch, and the source address for the FX8-24 blade.
• ARL minimum and maximum rates are set per circuit. They must be the same on either end of
a circuit, but individual circuits may have different rates.
• You can configure standby circuits by assigning a metric. In the following example, circuit 2 is
used only when circuit 1 fails. Refer to “FCIP circuit failover capabilities” on page 19 for a
description of circuit failover and the use of standby circuits.
switch:admin> portcfg fcipcircuit 8/12 create 1 192.168.11.79 192.168.1.25 -b
15500 -B 62000
switch:admin> portcfg fcipcircuit 8/12 create 2 192.168.11.8 192.168.1.26 -b
15500 -B 62000 -x 1
• When multiple FCIP tunnels are present on a switch and additional circuits are added to an
active tunnel, some frame loss can occur for a short period of time because the internal Fibre
Channel frame routing tables in the switch are refreshing. Therefore, add additional circuits
only during low I/O periods on the FCIP tunnel being modified. In addition, if deleting or adding
a circuit increases or decreases the total tunnel bandwidth, then disable and re-enable the
tunnel (VE_Port) after deleting or adding the circuit. This will allow the switch to adjust internal
routes to fully utilize the new bandwidth.
Verifying the FCIP tunnel configuration
After you have created local and remote FCIP configurations, verify that the FCIP tunnel and circuit
parameters are correct using the portshow fciptunnel command. Refer to the Fabric OS Command
Reference Manual for a description of the command syntax and output.
