• 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.

Gathering additional information

The following commands should be executed and their data collected before the supportsave

command is run. A supportsave can take ten minutes or more to run, and some of the information

is time critical.

• traceDump -n

• portTrace --show all

• portTrace --status

For issue specific to tunnel ports, run and collect the data from the following commands:

• slotShow

• portShow [slot number/]geport number

If possible, run and collect the data from the following commands:

• portShow ipif all [slot number/]geport number

Displays IP interface configuration for each GbE port (IP address, gateway and MTU)

• portShow arp all [slot number/]geport number

• portShow iproute all [slot number/]geport number

• portShow fciptunnel [slot number/]geport number [all | tunnel ID]

Displays complete configuration of one or all of the FCIP tunnels

• portShow fciptunnel -all -perf

• portShow fciptunnel all -c

• portShow fciptunnel all --circuit --perf --summary

• portShow fciptunnel all --circuit --perf --tcp --qos

• portCmd [--ping |--traceroute |--perf]

• Ping and traceroute utility

• Performance to determine path characteristics between FCIP endpoints

And finally gather the data from the supportSave -n command.

Refer to the Fabric OS Administrator’s Guide or Fabric OS Command Reference Manual for

complete details on these commands.
