Hello

Does FreeBSD offers anything similar like trunk(4) on
OpenBSD (link  
aggregation and link failover interface)?

Cheers,
Thomas

Hi

Thanks. I know about the netgraph ether/fec interfaces. But
I thought  
about a solution without netgraph. AFAIK Netgraph implies
overhead  
and ng_ehter is more complicated to set up. This is a
problem with  
non technical people. I'm happy they already know a bit
about   
ifconfig commands.

I will try it anyway.

Regards,
Thomas

two items.
1/ ng_fec only uses the config framework of netgraph. For
data it goes 
direct to the interfaces.
2/ netgraph is not that high an overhead.  (what made you
think it was?)

Ah good to know. Since this is for a network course it would
be easier
if this "trunk" could be setup via ifconfig
command. But I will try it.

Well I heard that netgraph has some overhead on various
conferences. I'm
planning to use such a feature on very very high loaded GigE
router,
every extra kernel hook could cost some performance, IMHO.

Thanks and cheers,
Thomas

it is possible that the extra overhead in netgraph may
influence such a 
high throughput system, but
one would have to test to know how much.. its overhead is
nto as high as 
one might think, despite
the fact that it was not designed to handle such high
throughputs, it 
does a reasonable job.
it is possible that the use of netisr() in some places slows
it down 
however..
