Set up interface bonding on FreeBSD 10

[maziar]

I want to set up interface bonding on FreebsdFreeBSD 10.

I have installed FreebsdFreeBSD on VMware Workstation 12 hosted on Windows,
and this is my configuration:

root@B1:/usr/home/maziar # kldstat
Id Refs Address            Size     Name
1    6 0xffffffff80200000 1755658  kernel
2    1 0xffffffff81956000 14810    if_lagg.ko
3    1 0xffffffff81a11000 2b58     uhid.ko
root@B1:/usr/home/maziar # cat /etc/rc.conf
ifconfig_em0="up"
ifconfig_em1="up"
cloned_interfaces="lagg0"
ifconfig_lagg0="laggproto lacp laggport em0 laggport em1"
ipv4_addrs_lagg0="10.0.8.16/24"
defaultrouter="10.0.8.1"
hostname="B1"
sshd_enable="YES"
dumpdev="AUTO"

But when iI restart network :
/etc/rc.d/netif restart && /etc/rc.d/routing restart

iI get this error :

And after restarting network setting iI lose my access to virtual machine, what is the problem? How can iI fix it?

Make sure both network interfaces have different MAC addresses, generate new ones if necessary. Also make sure you enable "promiscuous" mode on them.
