I recently came across a similar situation where I had to change the MTU across a bunch of different bsdrp boxes running as firewalls and routers and in the end after a lot of research I worked out the only way was either a reboot or possibly a restart of networking. Some machines had Intel(em) and Broadcom(bcd and bge) interfaces.

Hi,

after setting up in /etc/rc.conf:

ifconfig_igb{0,1,2,3}="mtu 9000 up"

and rebooting everything worked and I have mtu 9000 in lagg0 and 2 vlans

Thanks for hints!
