Hi all, hope you are well !!!
I have an issue with ex3400 ( Junos 15.1X53-D58.3 ) where I want to setup specific MTU on an interface ge-3/0/10 which is a L2 Access port with a specific Vlan assigned to it.
I go edit interface ge-3/0/10 >> Set mtu 1500.
Then, set disable >> commit
then, delete disable >> commit
This is to make sure interface goes down and then up to be 100% sure that change will apply.
When I do this, the VLAN where my interfece belongs to has MTU 1500 instead of 1514.
How is it possible 1 physical port 's settings to affect the entire Vlan users and loose connectivity ?
Is there any other step that must be done before this setting is applied to the interface ?
Thanks in advance.
