Gathering additional information

The following commands should be executed and their data collected before a supportsave is run
as a supportsave can take upwards of 10 minutes to execute and some of the information is time
critical.
In addition if it is a port/tunnel specific issue, run and collect the data from the following
commands:
If possible, run and collect the data from the following commands:
And finally gather the data from the supportsave -n command.
See Fabric OS Administrator's Guide or Fabric OS Command Reference for complete details on
these commands
Port mirroring
Port mirroring lets you configure a switch port to connect to a port to mirror a specific source port
and destination port traffic passing though any switch port. This is only supported between F_Ports.
This is a useful way to troubleshoot without bringing down the host and destination links to insert
an inline analyzer.

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.
Due to 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.
