    Filter-based VLAN assignment is very flexible compared to the port-based vlan assignment(static) .
    This feature can be used in scenarios that include multiple devices attached to a single switch port through an attached hub or passive switch.

    Let’s say that two PCs are attached to a hub and then to the switch port ge-0/0/0 ,from then to the upstream cloud. If we go by port-based vlan assignment method , both PCs will be part of same VLAN(11 in the example below) . If our requirement is to separate them into two vlans(11 and 22) , we can use filter-based VLAN .

    Step 1 :

    set vlans v11 vlan-id 11
    set vlans v11 interface ge-0/0/0.0
    set vlans v22 vlan-id 22
    set vlans v22 interface ge-0/0/0.0 mapping policy

    Step 2:

    set firewall family ethernet-switching filter separate-vlans term 1 from source-address
    set firewall family ethernet-switching filter separate-vlans term 1 then vlan v22
    set firewall family ethernet-switching filter separate-vlans term 2 then accept

    Step 3:

    set interface ge-0/0/0.0 family ethernet-switching filter input separate-vlans
    Because of term 1 , PC2 will now be part of v22 and because of term 2 , PC1 will be part of v11.
