Junos OS

How to do quick stop/start interface and dot1x authentication on juniper?

On cisco it is easy to do commands shutdown && no shutdown.

Hi,

Try the activate and deactivate command .

In any cause it is necessary do commit. Even if do commit confirmed 1 it is 1 minut idle.

I do 

[edit interfaces ge-0/0/6]
#set disable
[edit interfaces ge-0/0/6 unit 0]
#set disable
[edit interfaces ge-0/0/6 unit 0]
#commit confirmed 1

But it is not comfortably. Do you have yet method?

 

Hi,

 

start shell user root
ifconfig xe-y/z/w down
ifconfig xe-y/z/w up
exit

 

!! You should be careful with shell !! And don't forget to bring the interface up .

Thanks you,it is works. Can you tell more detail about up/down only physical interface or jointly with logical interface (unit 0), please?

Glad to hear that .

 

The command I provided you in the previous comment well do the job

For example :

 

admin@FW1> start shell user root
root@FW1% ifconfig ge-0/0/6 down
root@FW1% ifconfig ge-0/0/6 up
root@FW1% exit

 

Just don't forget to bring the interface up, because then Your interface will display as & stay down in junos CLI printouts and MIB without apparent reason.

 

Please also take a look at the link I provided you . There is so much informations written by experts .

In another comments disscuss perhaps do va script, for me on this time no intresting, but in the future will come in handy.

 

I would like to clarify the behavior of the physical and logical interfaces. Is it enough only physical interface root@test-jun:RE:0% ifconfig ge-0/0/8 down or necessary yet down and logical inteface (unit 0) root@test-jun:RE:0% ifconfig ge-0/0/8.0 down ?

Hi,

 

It also support logical interfaces . If you meant something else , please clarify the question .

Provided here example from lab switch :

 

{master:0}
admin@LabB> start shell user root
Password:
root@LabB:RE:0% ifconfig ge-0/0/11.0 down
root@LabB:RE:0% exit
exit

{master:0}
admin@LabB> show interfaces terse | match 11
ge-0/0/11 up up
ge-0/0/11.0 down up eth-switch

{master:0}
admin@LabB> start shell user root
Password:
root@LabB:RE:0% ifconfig ge-0/0/11.0 up
root@LabB:RE:0% exit
exit

{master:0}
admin@LabB> show interfaces terse | match 11
ge-0/0/11 up up
ge-0/0/11.0 up up eth-switch

{master:0}
admin@LabB> start shell user root
Password:
root@LabB:RE:0% ifconfig ge-0/0/11 down
root@LabB:RE:0% exit
exit

{master:0}
admin@LabB> show interfaces terse | match 11
ge-0/0/11 down down
ge-0/0/11.0 up down eth-switch

{master:0}
admin@LabB> start shell user root
Password:
root@LabB:RE:0% ifconfig ge-0/0/11 up
root@LabB:RE:0% exit
exit

{master:0}
admin@LabB> show interfaces terse | match 11
ge-0/0/11 up up
ge-0/0/11.0 up up eth-switch

{master:0}
admin@LabB>

On cisco devices in order to do up/down inteface enough to make shutdown/no shutdown. On juniper devices with they concept logical interface (unit) in order to do up/down interface enough to make % ifconfig ge-0/0/8 up/down only on physical interface or necessary else to do % ifconfig ge-0/0/8.0 up/down and on logical interface?

 

P.S. i am sorry for me english.

Hi,

Well, its not the same concept with cisco . Every company has its concepts .
With juniper (junos) you need to log in the shell as a root user in order to bring down\up any physical\logical interface .
You don't need the ge-0/0/8.0 (unit 0) in order to bring down physical interface . in enough to use ge-0/0/8 . But if we're talking about logical interface m then yes you need the (unit 0) .
I just brought to you two examples and a link to discussion on you question .

HTH

Thanks very much for explanation.

How would I check if an interface has been set to down in shell?
