VLAN Configuration Comparision - Cisco & Juniper

If you are familiar with Cisco switches, and using Cisco switches fairly well, this post will help you to boost your confidence as a Juniper network engineer.

If you can configure a Cisco switch, then you also can configure a JUNOS based switch :)  here you go..

 IOS

#vlan-database

(vlan)#vlan 5 name Internet

(vlan)#vlan 6 name Intranet

(vlan)#apply

JUNOS

set vlan Internet vlan-id 5

set vlan Intranet vlan-id 6

Assign an IP addressto a VLAN:

IOS

(config)#interface vlan 5

(config-if)#ip address 10.10.10.254 255.255.255.0

JUNOS

set interfaces vlan unit 5 family inet address 10.10.10.254/24

set vlan Internet l3-interface vlan.5

Assigning a port to aVLAN (Access):

IOS

(config)#interface fastEthernet 2/2

(config-if)#switchport mode access

(config-if)#switchport access vlan 5

JUNOS

set interfaces fe-2/0/2 unit 0 family ethernet-switching port-mode access

set interfaces fe-2/0/2 unit 0 family ethernet-switching vlan members Intranet

Assigning a port to aVLAN (6 Trunked with 5 Native)

IOS

(config)#interface fastEthernet 2/2

(config-if)#switchport mode trunk

(config-if)#switchport trunk encapsulation dot1q

(config-if)#switchport trunk native vlan 5

(config-if)#switchport trunk allowed vlan 5,6

JUNOS

set interfaces fe-2/0/2 unit 0 family ethernet-switching port mode trunk

set interfaces fe-2/0/2 unit 0 family ethernet-switching native-vlan-id 5

set interfaces fe-2/0/2 unit 0 family ethernet-switching vlan members 6
