The MTU on lagg0.10 has shrunk by 4 (size of VLAN tag). Is there a way
of avoiding that?
That's my working setup (hardware is based on
http://www.supermicro.com/products/system/4U/6047/SSG-6047R-E1R36L.cfm)
#/etc/rc.conf:
ifconfig_igb0="mtu 9000 up"
ifconfig_igb1="mtu 9000 up"
ifconfig_igb2="mtu 9000 up"
ifconfig_igb3="mtu 9000 up"
cloned_interfaces="lagg0 vlan14 vlan100 vlan900"
ifconfig_lagg0="laggproto lacp laggport igb0 laggport igb1 laggport igb2
laggport igb3"
#VLAN
ifconfig_vlan14="inet 192.168.1.72/24 vlan 14 vlandev lagg0"
ifconfig_vlan100="inet 192.168.21.253/24 vlan 100 vlandev lagg0"
ifconfig_vlan900="inet 172.25.25.72/24 vlan 900 vlandev lagg0"
% ifconfig -a | grep mtu
igb0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
igb1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
igb2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
igb3: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
vlan14: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
vlan100: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu
9000
vlan900: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu
9000
Reboot is needed after MTU change.
Cheers
