Setting VLAN MTU in GUI doesn't work?

[highc]

Hi, it appears that setting a different (lower) MTU size for a VLAN than for the physical interface doesn't work in the GUI. It does work on the console, though.

LAN (on LAGG0) with MTU size 9000.

VLAN70 (on LAGG0) with MTU size 1492

ifconfig on console after a reboot:

After I run "ifconfig lagg0.70 mtu 1492" on the console, it looks ok:

How can I make this persistent, if it's not working through the GUI, please?

Thanks!

Sorry for pushing. Is this normal, did I miss anything, should I turn this into a bug report?

Thanks.
