OS for EX Series Ethernet Switches, Release 10.4
Settings
Any Layer 2 switch with multiple 1-Gigabit Ethernet ports and at least one 1-Gigabit
Ethernet uplink module
EX4200-24F, 24 1-Gigabit Ethernet fiber SPF ports (ge-0/0/0 through ge-0/0/23); one
2-port 10-Gigabit Ethernet XFP uplink module (EX-UM-4SFP)
vlan1, tag 101
vlan2, tag 102
vlan3, tag 103
vlan4, tag 104
vlan5, tag 105
vlan1: 1.1.1.0/24 (addresses 1.1.1.1 through 1.1.1.254)
vlan2: 2.1.1.0/24 (addresses 2.1.1.1 through 2.1.1.254)
vlan3: 3.1.1.0/24 (addresses 3.1.1.1 through 3.1.1.254)
vlan4: 4.1.1.0/24 (addresses 4.1.1.1 through 4.1.1.254)
vlan5: 5.1.1.0/24 (addresses 5.1.1.1 through 5.1.1.254)
On the access switch: ge-0/1/0
On the distribution switch: ge-0/0/0
To quickly create and configure subinterfaces on the access switch, copy the following
commands and paste them into the switch terminal window:
[edit]
set interfaces ge-0/1/0 vlan-tagging
set interfaces ge-0/1/0 unit 0 vlan-id 101 family inet address 1.1.1.1/24
set interfaces ge-0/1/0 unit 1 vlan-id 102 family inet address 2.1.1.1/24
set interfaces ge-0/1/0 unit 2 vlan-id 103 family inet address 3.1.1.1/24
set interfaces ge-0/1/0 unit 3 vlan-id 104 family inet address 4.1.1.1/24
set interfaces ge-0/1/0 unit 4 vlan-id 105 family inet address 5.1.1.1/24
To configure the subinterfaces on the access switch:
On the trunk interface of the access switch, enable VLAN tagging:
1.
[edit interfaces ge-0/1/0]
user@access-switch# set vlan-tagging
Bind vlan1's VLAN ID to the logical interface:
2.
[edit interfaces ge-0/1/0]
user@access-switch# set unit 0 vlan-id 101
