EX Series switches support receiving and forwarding routed or bridged Ethernet frames
with 802.1Q VLAN tags. The logical interface on which untagged packets are to be received
must be configured with the same native VLAN ID as that configured on the physical
interface.
To configure the native VLAN ID using the CLI:
Configure the port mode so that the interface is in multiple VLANs and can multiplex
1.
traffic between different VLANs. Trunk interfaces typically connect to other switches
and to routers on the LAN. Configure the port mode as
[edit interfaces ge-0/0/3 unit 0 family ethernet-switching]
user@switch# set port-mode trunk
Configure the native VLAN ID:
2.
[edit interfaces ge-0/0/3 unit 0 family ethernet-switching]
user@switch# set native-vlan-id 3
