Juniper IOS Cheat Sheet - EX Switch Commands

Juniper IOS Cheat Sheet
EX Series Ethernet Switch Commands

by Steven Jordan November 25th, 2013

Juniper commands to configure and manage a Juniper EX switch.  My formal training is with Cisco; I was lost the first couple times I used JUNOS CLI.  These commands should help out other Cisco minded people.

N.B.  The list below is blog friendly.  I included a printer friendly Word version here.

General Commands:

Operation Mode:	#CLI
Move up tree:	#up
Move down tree:	#down
Enter Configuration:	#config
View Configuration:	#show
Ascend to top of tree:	#top
Descend one or multiple levels:	#edit
Add line to config:	#set
Delete a line:	#delete

Changes:

Save changes	#commit
* Confirm changes are permanent.
View changes since    previous commit:	#show | compare
Verify changes:	#commit check
Confirm changes:	#commit confirmed
*Commit confirm will roll      back after 10 minutes.
Descend one or multiple levels:	#edit
Add line to config:	#set
Delete a line:	#delete

Configure Physical Interface:

#set interfaces ge-0/0/0 unit 0 family inet address 10.1.1.1/24

Configure SVI/RVI:

Configure an IP on the RVI. Bind the RVI to a VLAN

* For additional RVIs, increase the unit number. **It is recommended the RVI unit number match the VLAN-id.

#set interfaces vlan unit 1 family inet address 192.168.1.2/24

#set vlans vlan-1 l3-interface vlan.1

Configure VLAN:

Minimum VLAN config is define vlan-name.   #set vlans servers

2.  Assign VLAN-ID for tags:

#set vlans servers vlan-id 100

3.  To delete VLAN replace the command set with “delete”.

Configure VLAN Range:

VLAN range defines a range of VLANs. Syntax:  set vlans vlan-name vlan-range low-high             #set vlans production vlan-range 90-100

Configure VLAN Membership

Assign ports via VLAN-centric method.   #set vlans servers interface ge-0/0/0.0

2.  Assign ports via Port-centric method.

#set interfaces ge-0/0/0.0 family Ethernet-switching vlan members servers    OR:           #set interfaces ge-0/0/0.0 family Ethernet-switching vlan members 100           #set interfaces fe-0/0/0.0 family Ethernet-switching vlan members [1 5 7-100] For access port, configure all the VLAN membership under the VLAN stanza. For trunk ports, configure all the VLAN membership under the interface (port-centric method

Configure Port Roles:

Access Ports:          #set interface ge-0/0/0.0 family Ethernet-switching port-mode access Trunk:               #set interface ge-0/0/0.0 family Ethernet-switching port-mode trunk Routed:             #set-interface ge-0/0/0.0 family inet address 192.168.1.0/24

Execute CLI Commands:

#run show Shutdown:

#request system halt
