Closed, ResolvedPublic
Actions

Description

An MTU can be set on a child interface, such as a VLAN or QinQ, that is larger than the parent interface. It is not currently handled gracefully and instead produces a python error.

Example config:

set interfaces ethernet eth0 mtu 1500
set interfaces ethernet eth0 vif 1000 mtu 9000
