netplan -- cannot set MTU

[0x19xx]

Hello everyone,

I have an Ubuntu Server 17.10 that Im trying to configure a MTU of 9000. The problem is that whatever I specify in the netplan config file (well, I mean the MTU), it does not get picked up by netplan apply.

Here is my config:

network:  version: 2
  renderer: networkd
  ethernets:
    eth0:
      mtu: 9000
      match: 
        macaddress: xx:xx:xx:xx:xx:xx
    eth1:
      mtu: 9000
      match: 
        macaddress: xx:xx:xx:xx:xx:xx 
  bond0:
[etc]

I checked the manual and the way I define the value should work.


Anyone have experience with this?

I experience the same problem on 18.04 LTS.
Googled around a bit and it found reports that this issue was seen long ago and fixed.
