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=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC> ether 00:08:9b:d4:91:64 inet 1.1.1.1 netmask 0xffffff00 broadcast 1.1.1.255 media: Ethernet autoselect status: active laggproto lacp laggport: em3 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING> laggport: em2 flags=18<COLLECTING,DISTRIBUTING> laggport: em1 flags=18<COLLECTING,DISTRIBUTING> laggport: em0 flags=18<COLLECTING,DISTRIBUTING> MACHINE2 # ifconfig lagg0 lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC> ether 00:08:9b:d3:72:60 inet 1.1.1.2 netmask 0xffffff00 broadcast 1.1.1.255 media: Ethernet autoselect status: active laggproto lacp laggport: em3 flags=18<COLLECTING,DISTRIBUTING> laggport: em2 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING> laggport: em1 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING> laggport: em0 flags=1c<ACTIVE,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!
