Hello,
I'm trying to use two gigabit links together using ng_one2many.
I haven't done this before, so here is the environment:
FreeBSD 6 system with four gigabit interfaces, two of the four are going
to be used a single interface. I've attached em0 and em1 to a gigabit
switch and read manual pages / googled for information on how to configure
this.
I have the following script to set things up:
ngctl mkpeer em0: one2many upper one
ngctl connect em0: em0:upper lower many0
ngctl connect em1: em0:upper lower many1
ngctl msg em1: setpromisc 1
ngctl msg em1: setautosrc 0
ngctl msg em0:upper \
setconfig "{ xmitAlg=1 failAlg=1 enabledLinks=[ 1 1 ] }"
I get 50% packet loss when using this. It seems to me like only the em0
interface is operating properly, although both NICs are connected and work
alright without ng_one2many.
Any clues as to what I am doing wrong / guides to implementation
ng_one2many? Is this email related to my problem?
