204 Using the FC-FC routing service
For more information about the fabricShow command, see the Fabric OS Command Reference Manual.
Range of output ports
The edge fabric detects only one front domain from an FC router connected through multiple output ports.
The output port of the front domain is not fixed to 0; the values can be in a range of 129–255. The range
of the output ports connected to the xlate domain is also 129–255. This range enables the front domain to
connect to 127 remote xlate domains.
To display the range of output ports connected to the xlate domains
1. Log in to the FC router.
2. Enter the lsDbShow command on the edge fabric.
The following example shows the range of output ports.
The following example also shows the use of the lsDbShow display on the edge fabric. The front
domain, domain 3, has two links representing two EX_Port connections with output ports 129 and 132.
To verify normal operation
1. Connect the FC router to an edge fabric switch via multiple EX_Ports from the same router.
2. Confirm that the ports are enabled with portCfgShow.
3. Confirm that the EX_Ports share the same front domain PID and node WWN, using the
portCfgExport command.
NOTE: Abnormal operation for front domain consolidation exists when the ports do not come
online or in the Normal Operation setup described previously, the EX_Ports do not share the same
front domain consolidation PID and node WWN.
Support
In case of an unexpected failure at the customer site, save the output from the supportShow and
supportSave run on the FC router and edge fabric switches.
Proxy devices
A 400 MP Router or 4/256 SAN Director with an B-Series MP Router blade achieves interfabric device
connectivity by creating proxy devices (hosts and targets) in attached fabrics that represent real devices in
other fabrics. For example, a host in Fabric 1 can communicate with a target in Fabric 2 as follows:
• A proxy target in Fabric 1 represents the real target in Fabric 2.
• Likewise, a proxy host in Fabric 2 represents the real host in Fabric 1.
The host discovers and sends Fibre Channel frames to the proxy target. The 400 MP Router or 4/256 SAN
Director with an B-Series MP Router blade receives these frames, translates them appropriately, then
delivers them to the destination fabric for delivery to the target.
