Hello world,

none of the FreeBSD documents i studied reflect the correct HowTo setup
link aggregation. I'll try to submit my input in the doc projekt but
first of all archive it here:

1. Don try to establish link aggregation remote. You'll probally fail.
You can do it only with remote serial or totally scripted.

2. The main lag of information in the FreeBSD documentation is "What do
i have to put in the /etc/rc.conf?"

Answer (tested, for experienced user only):

ifconfig_vr0="up"
ifconfig_dc0="up"
cloned_interfaces="lagg0"
ifconfig_lagg0="laggproto roundrobin laggport vr0 laggport dc0
192.168.2.1 netmask 255.255.255.0" defaultrouter="192.168.2.254"

Best regards,
Stefan

Thanks to Quinn Wood who mailed me the following link:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-aggregation.html

Obviously i missed the advanced chapter.

After aggregating two links i cant access SNMP over the aggregated
link anymore. My FreeBSD machine collects some statistics of a direct
connected router via SNMP. After changing this link to connect with
lagg0 snmpwalk gives me a timeout.

Is this a bug?

Best regards,

Stefan

Damn - there was a firewall in the way.
