 I changed lagg to not copy the MTU of the 1st physical interface
 because the other bug that is similar to (1) of this report could not
 be resolved
 without the behavior change.
 For that reason, please use the following command to set MTU to lagg(4) ins=
 tead.
 
          !ifconfig wm0 up
          !ifconfig wm1 up
          create
          mtu 9000
          laggproto lacp laggport wm0 laggport wm1 192.168.2.1 netmask =3D
          255.255.255.0
          up
 
 Thanks,
