FCIP Trunking

Active-active configuration

The following examples shows an active-active configuration in which two circuits are configured

with the same metric, one circuit going over xge0 and the other circuit going over the crossport

using xge1 as the external port. The metric values of both the circuits are the same (default value),

so both circuits send data. The load is balanced across these circuits. Effective bandwidth of the

tunnel in this example is 2 Gbps. For more information on configuring crossports, refer to

“Crossports” on page 13.

1. Configure an IP address on interface xge0.

portcfg ipif 8/xge0 create 192.168.11.20 255.255.255.0 1500

2. Configure an IP address on crossport interface xge1.

portcfg ipif 8/xge1 create 192.168.10.10 255.255.255.0 1500 –x

3. Create a tunnel with one circuit going over xge0.

portcfg fciptunnel 8/22 create 192.168.11.20 192.168.11.21 1000000

4. Add another circuit, going over crossport xge1, to the tunnel.

portcfg fcipcircuit 8/22 create 1 192.168.10.10 192.168.10.11 1000000

5. Display local and crossport interface details for xge0.

portshow ipif 8/xge0

NOTE

If the source and destination addresses are on different subnets, you must configure IP routes to

the destination addresses. Refer to “Configuring an IP route” on page 41.

NOTE

For more information on using Fabric OS commands, optional arguments, and command output

refer to the Fabric OS Command Reference Manual.

Active-passive configuration

The following example shows an active-passive configuration in which two circuits are configured

with the different metrics, one circuit going over xge0 and the other circuit going over the crossport

using xge1 as the external port. In this example, circuit 1 is a failover circuit because it has a higher

metric. When circuit 0 goes down, the traffic is failed over to circuit 1. Effective bandwidth of the

tunnel in this example is 1 Gbps.
