How do you create a VLAN in Junos?
Support
- From configuration mode, create the VLAN and add access vlan members to it:

How do I configure native VLAN in Juniper?
To configure the native VLAN ID using the CLI:
- Configure the port mode as trunk so that the interface is on multiple VLANs and can multiplex traffic between different VLANs. Trunk interfaces typically connect to other switches and to routers on the LAN.
- Configure the native VLAN ID:
What is unit 0 family in Juniper?
The 0 just refers to the first logical interface. It’s good practice (but not required) to keep the unit number in sync with the VLAN id. In that case unit 0 often refers to the untagged interface. family inet refers to the IPv4 address family.

You can have three vlans on one port if the switch configuration allows it. Mine allows one for data and one for VoIP. The quick answer is yes, That’s called a trunk.

Then, three interfaces are assigned to that VLAN, and these interfaces, which function in access mode, transmit traffic among themselves. In the example, all users connected to the interfaces ge-0/0/1, ge-0/0/2, and ge-0/0/3 can communicate with each other, but not with users on other interfaces in this network.
