Description Jean-Marc Liotier 2023-05-23 00:09:21 UTC 
A Wired Ethernet connection's "Wired" tab offers a "MTU:" setting field that sets the interface's MTU.

A Bond connection offers no such field, so its MTU remains at its default 1500 even when the bonded connections are set to a higher value.

The "Bonded connections" component of a Bond connection offer a MTU setting field to a Wired Ethernet connection, but it is irrelevant to setting the MTU for the Bond connection.

Setting the Bond connection is possible from a console using a command such as 'ip link set bond0 mtu 9000'. That setting should be available through a "MTU:" setting field like the one offered in the Wired Ethernet connection's "Wired" tab.

For proof of backend functionality I gave an 'ip' command, but should have mentioned a 'nmcli' command instead - so here it is: ''nmcli connection modify bond0 802-3-ethernet.mtu 9000'
