Checklist for configuring FCIP links
Use Table 100 as a checklist for creating FCIP links.
See the Fabric OS Command Reference Manual for detailed information on these commands.
Troubleshooting FCIP links
The following list contains information for troubleshooting FCIP links:
• When deleting FCIP links, you must delete them in the exact reverse order they were created. That is,
delete first the tunnels, then the IP interfaces, and finally the port configuration. The IP route information
is removed automatically at this point.
• IP addresses are retained by slot in the system. If FR4-18i blades are moved to different slots without first
deleting configurations, errors can be seen when trying to reuse these IP addresses.
• The portCmd ping command only verifies physical connectivity. This command does not verify that
you have configured the ports correctly for FCIP tunnels.
• One port can be included in multiple tunnels, but each tunnel must have at least one port that is unique
to that tunnel.
• Ports at both ends of the tunnel must be configured correctly for a FCIP tunnel to work correctly. These
ports can be either VE_Ports or VEX_Ports. A VEX_Port must be connected to a VE_Port.
• When configuring routing over an FCIP link for a fabric, the edge fabric will use VE_Ports and the
backbone fabric will use VEX_Ports for a single tunnel.
• If an FCIP tunnel fails with the “Disabled (Fabric ID Oversubscribed)” message, the solution is to
reconfigure the VEX_Port to the same Fabric ID as all of the other ports connecting to the edge fabric.
WAN performance analysis tools
Introduced in Fabric OS 5.2.0, WAN analysis tools are designed to estimate the end-to-end IP path
performance characteristics between a pair of FCIP port endpoints. WAN tools include the following
commands and options:
• portCmd ipPerf—Characterizes end-to-end IP path performance between a pair of FCIP ports. You
can use the WAN tool ipPerf only on the FR4-18i or 400 MP Router FCIP ports running Fabric OS
v5.2.0 or later software.
• portShow fcipTunnel—Displays performance statistics generated from the WAN analysis.
Table 103 Steps for configuring FCIP links
Step Command
1. Enable persistently disabled ports. portcfgpersistentenable [slot/]port
2. Disable the ports while performing
the configuration.
portdisable [slot/]port
3. Configure the port type as VE_Port or
VEX_Port for both ports for a tunnel.

4. Configure the IP interface for both
ports of a tunnel.
portcfg ipif [slot/][ge]port create ipaddr
netmask mtu_size
5. Verify the IP interface for both ports
of a tunnel.
portshow ipif [slot/][ge]port
6. Configure FCIP tunnels. portcfg fciptunnel [slot/][ge]port create
tunnel_id remote_ipaddr local_ipaddr comm_rate
