vxlan in Linux kernel 3.7

vxlan in Linux kernel 3.7

[Qin, Xiaohong]

Hi All,

I have installed kernel 3.7 on my Linux box, see the following uname -a output,

uname -a
Linux c210-m2-sib-3 3.7.0-030700-generic #201212102335 SMP Tue Dec 11 04:36:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Does that mean I've got VXLAN module loaded or I still need to go through some extra steps to enable or configure it? Do you have any VXLAN setup or configuration document by chance?

Thanks.

Dennis Qin

P.S. If this is not the right place to ask this kind of questions, please let me know which mailing list I should use.

VXLAN driver is part of the kernel config. 
If using a vendor supplied kernel, most likely it is available as a module.
Try:
   /sbin/modinfo vxlan
If you see 'ERROR: Module vxlan not found' then vxlan was not configured.
You will also need to have current iproute2 utilities.
   $ ip -V
ip utility, iproute2-ss121211

Hi Stephen,

Thanks very much for the tip. Here is the output on my box,

/sbin/modinfo vxlan
filename:       /lib/modules/3.7.0-030700-generic/kernel/drivers/net/vxlan.ko
alias:          rtnl-link-vxlan

license:        GPL
srcversion:     D5253D8FFAF3FEF6A3A3026
depends:

vermagic:       3.7.0-030700-generic SMP mod_unload modversions
parm:           udp_port:Destination UDP port (uint)
parm:           log_ecn_error:Log packets received with corrupted ECN (bool)

# ip -V
ip utility, iproute2-ss111117

So I think I'm all set to give it a try?

Thanks.

That version is way to old to know about vxlan configuration.
The last digits of the iproute version are the date it was
released.  That date is November 17 2011 which is the 3.1 version.
You need 3.7 which was released on December 11 2012, or you can
use latest from iproute2 git repository.
