1.accessの設定

■設定例
interfaces {
ge-0/0/0 {
unit 0 {
family ethernet-switching {
port-mode access;
vlan {
members vlan100;
}
}
}
}
}
vlans {
vlan100 {
vlan-id 100;
}
}

2.untagとtag vlanを混在させる場合

■設定例
interfaces {
ge-0/0/0 {
unit 0 {
family ethernet-switching {
port-mode trunk;
vlan {
members [ vlan100 vlan101 vlan102 ];
}
native-vlan-id vlan1;
}
}
}
}
vlans {
vlan1 {
vlan-id 1;
}
vlan100 {
vlan-id 100;
}
vlan101 {
vlan-id 101;
}
vlan102 {
vlan-id 102;
}
}
