MTU physicla intefaces vs vlans MTU

Hello,

About MTU, how does a Viprion behave when MTU is 9000 on physical interfaces but 1500 on vlans ?

Does he takes 9000 or 1500 ? What are the risks to have such a difference beetween MTUs ?

Thanks.

    after some searching i would say that traffic going through the VLAN uses 1500 and that having the interface on 9000 isn't an issue.
