blades to gather WAN performance data.
When deleting FCIP links, you must delete them in the exact reverse order they were created.
That is, first delete 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 an 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.
Because of an IPsec RASLog limitation, you may not be able to determine an incorrect
configuration that causes an IPSec tunnel to not become active. This misconfiguration can
occur on either end of the tunnel. As a result, you must correctly match the encryption method,
authentication algorithm, and other configurations on each end of the tunnel.
