This is very similar to https://bugs.launchpad.net/bugs/1724895, but I decided to open this as i have tried what has succeeded for others. Thanks for any assistance.
I'm trying to set the MTU to 1500 and using a match on mac address, but after a netplan apply or reboot, it does not change or stick. This is on a EC2 T2.Medium instance. Actual configuration from a dev server:
network:
version: 2
ethernets:
eth0:
match:
macaddress: 12:0f:ae:49:5d:06
mtu: 1500
dhcp4: true
nameservers:
search: [ devbuilds.vpc, ec2.internal ]
$> cat /var/run/systemd/network/10-netplan-eth0.link
[Match]
MACAddress=12:0f:ae:49:5d:06
[Link]
WakeOnLan=off
MTUBytes=1500
$> cat /var/run/systemd/network/10-netplan-eth0.network
[Match]
MACAddress=12:0f:ae:49:5d:06
[Network]
DHCP=ipv4
Domains=devbuilds.vpc ec2.internal
[DHCP]
UseMTU=true
RouteMetric=100
$> ip link show eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9001 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 12:0f:ae:49:5d:06 brd ff:ff:ff:ff:ff:ff
# manually set MTU
$> sudo ip link set dev eth0 mtu 1500
$> ip link show eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 12:0f:ae:49:5d:06 brd ff:ff:ff:ff:ff:ff
$> sudo netplan generate
$> sudo netplan apply
$> ip link show eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9001 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 12:0f:ae:49:5d:06 brd ff:ff:ff:ff:ff:ff
The last netplan commands could be replaced with a reboot with the same result. This configuration seemed to help others, so hopefully i'm simply missing something or perhaps this is related to EC2?

[Impact]
DHCP configurations where custom settings (MTU) need to be applied. This is a subset of the changes presented in bug 1759014.
[Test case]
1) Configure netplan for the particulars of the network by configuring an appropriate dhcp{4,6}-override stanza:
network:
version: 2
ethernets:
engreen:
dhcp4: true
dhcp4-overrides:
use-mtu: false
Additionally, if so required, add a custom MTU to the configuration. e.g.
mtu: 1700
(See https://netplan.io/reference#dhcp-overrides for the available options)
2) Run 'netplan apply' or reboot to have the configuration applied.
3) Validate that the routes / DNS are properly ignored and/or replaced by the defined values.
[Regression potential]
Minimal; this adds new values to the configuration generated for networkd or NetworkManager. Existing configurations will remain unchanged, but new configurations using the dhcp{4,6}-overrides fields will benefit from additional flexibility.
