Hi Xu Zhe,
If I were you I would first of all check cables. They might be the cause.
Secondly, if cables are good, to me this report very much resembles a PR I
reported a
few weeks ago - http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/179926
Check its set and look at the patch I submitted. It's a pity there's no
response to it.
Greetings,
Boris

Hi, all,
I am trying to use lagg to bind four 1Gb NIC into 4Gb one. I was testing
this using two machines running FreeBSD 8.2, each of the machine has
four 1Gb ethernet card, and connected correspondingly, means:
MACHINE1 MACHINE2
em0 -em0
em1 -em1
em2 -em2
em3 -em3
Then I created vlan called 'lagg0' on each machine using:
ifconfig lagg0 create
ifconfig lagg0 laggproto lacp laggport em0 laggport em1 laggport em2
laggport em3
ifconfig lagg0 1.1.1.1/24
ifconfig lagg0 up
And do this on MACH2 too, only change IP from 1.1.1.1 to 1.1.1.2.
But I cannot ping each other, since none of the link is both active:
MACHINE1
# ifconfig lagg0
lagg0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu 1500
options=219bRXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC
ether 00:08:9b:d4:91:64
inet 1.1.1.1 netmask 0xff00 broadcast 1.1.1.255
media: Ethernet autoselect
status: active
laggproto lacp
laggport: em3 flags=1cACTIVE,COLLECTING,DISTRIBUTING
laggport: em2 flags=18COLLECTING,DISTRIBUTING
laggport: em1 flags=18COLLECTING,DISTRIBUTING
laggport: em0 flags=18COLLECTING,DISTRIBUTING
MACHINE2
# ifconfig lagg0
lagg0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu 1500
options=219bRXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC
ether 00:08:9b:d3:72:60
inet 1.1.1.2 netmask 0xff00 broadcast 1.1.1.255
media: Ethernet autoselect
status: active
laggproto lacp
laggport: em3 flags=18COLLECTING,DISTRIBUTING
laggport: em2 flags=1cACTIVE,COLLECTING,DISTRIBUTING
laggport: em1 flags=1cACTIVE,COLLECTING,DISTRIBUTING
laggport: em0 flags=1cACTIVE,COLLECTING,DISTRIBUTING
So, em3 is active on MACHINE1 but not active on MACH2, while em0-em2 are
active on MACH2 but not on MACHI1.
What might be the problem?
Thanks!
Peter
