FCIP tunnel issues
The following are common FCIP tunnel issues and recommended actions for you to follow to fix the
issue.
Symptom FCIP tunnel does not come Online.
Probable cause and recommended action
Confirm the following steps.
1. Confirm GE port is online.
portshow ge1
Eth Mac Address: 00.05.1e.37.93.06
Port State: 1 Online
Port Phys: 6 In_Sync
Port Flags: 0x3 PRESENT ACTIVE
Port Speed: 1G
2. Confirm IP configuration is correct on both tunnel endpoints using the following command.
portshow ipif ge1
3. Enter the portCmd --ping command to the remote tunnel endpoint from both endpoints.
The -s value is the source IP address; the –d value is the destination IP address.
portcmd --ping ge1 -s 11.1.1.1 -d 11.1.1.2
If the command is successful, then you have IP connectivity and your tunnel should come up. If
not continue to the next step.
When using VLANS, VLAN tagging ensures that test traffic traverses the same path as real FCIP
traffic. A VLAN tag entry for both the local and remote sides of the route must exist prior to
issuing the portCmd --ping or portCmd --traceroute commands. Refer to “Managing the VLAN
tag table” on page 28 for details.
4. Enter the portCmd
--traceroute command to the remote tunnel endpoint from both endpoints.
portcmd --traceroute ge1 -s 11.1.1.1 -d 11.1.1.2
5. The tunnel or route lookup may fail to come online because of a missing but required IP route.
If there are routed IP connections that provide for the FCIP tunnel, then both ends of the tunnel
must have defined ipRoute entries.
Refer to the “Configuring an IP route” on page 41 to review the setup of the IP route.
6. Confirm FCIP tunnel is configured correctly using the following command:
portshow fciptunnel ge1 all
The Compression, Fastwrite, and Tape Pipelining settings must match the opposite endpoint or
the tunnel may not come up. Remote and local IP and WWN should be opposite each other.

Reference Manual.
