Hi Roy,

There are two versions of FCoE formats:
- The one defined in http://www.t11.org/ftp/t11/pub/fc/bb-4/07-303v0.pdf
- The one defined in http://www.t11.org/ftp/t11/pub/fc/bb-5/07-479v0.pdf
Do you mean that your Nexus switch only support the bb-4 format?

Solaris FCoE only supports the bb-5 format. We have tested interoperability between Solaris FCoE target and Emulex LP21000-M CNA initiator across the Nexus switch, so I guess your (or at least the CNA team's) switch also supports the bb-5 format. The Nexus switch in our lab has a system version 4.0(0)N1(1a), what's yours?

Thanks,
Zhong

Zhong,
 
The problem is that I'm using an older Nexus switch that only works with pre T11 frame format.  Is there a way to modify this parameter in the driver to work with older format?
 
Thanks,
Roy

Hi Roy,

Thanks for trying out Solaris FCoE software!

Hi,
 
I have configured a fcoe initiator using fcoe-nightly-nd-bins-20081121.i386.tar.bz2 build and connected to a Nexus switch but not seeing the WWN in the Nexus flogi database.  The NIC is Intel 10G XF SR adapter, and I can ping other NICs connected to the Nexus switch.  Is there a special switch setting required or is there a workaround to make this work.

Which OpenSolaris release are you using with the FCoE initiator? Please run "mdb -k" as root and issue "*fcoe_trace_buf/s" and "::fptrace" on the FCoE initiator host, send me the output together with the running-config of your Nexus switch. I'll take a look to see what's going on.

 
Any notes available for the SUNWfctl - leadville PLOGI to FCoE target issue workaround.

You don't need that if you are testing FCoE to FCoE. But if you are using Leadville FC initiator, you need to apply the package on the initiator host, otherwise the FC initiator may not log in to FCoE nodes.

Thanks & Regards,
Zhong

 
Thanks,
Roy
