Switching

Hey Everyone, 

I'm needing to set a pretty simple configuration change to over 100 ex2200 switches. Basically I want to have the switches report to our syslog server. So the command would be:

set system syslog host sysloghostserver any alert

I've been googling all night and see a lot of avenues, but none of them look quite right. I'd happily ssh into each switch and paste a command. But I'm not even sure how to do that. From what i understand once logged in I need to type cli and the configure and then paste the above command, then commit and quit. 

It would be great if I could somehow string all that stuff together, but I can't seem to figure out how to switch modes in one command. Like on linux you can pipe commands together.

Some of the stuff on this page looked promising, but total overkill for what i'm trying to accomplish.

Does anyone have any suggestions? 

Only if you log in as root, would you need to enter cli, otherwise you would need to enter configure/edit to enter configuration mode. You can just copy th ecommand and paste in command. The method that would work also is scripting (Junos automation) or if you had Junos Space, you could push config to all in batch I think batch of 20 but it would be far easier 

So if you log in as root

root%cli

root>configure

root# 

set system syslog host syslog host <ip-address> any alert
root#commit an-quit
root>exit
root%exit

Maybe this will help you, although is not the fastest way. Create a file in one central location of your network and from there connect to all devices and apply the configuration:

lab@ubuntu:/home/pubftp$ ls -l | grep script
-rwxrwxrwx 1 lab     lab             68 Sep 18 11:35 script.sh
lab@ubuntu:/home/pubftp$ cat script.sh
cli -c "edit;set interfaces ge-0/0/17 description TEST;commit;exit"
lab@ubuntu:/home/pubftp$
lab@ubuntu:/home/pubftp$ ssh root@172.30.145.153 'sh -s' < script.sh
root@172.30.145.153's password:
Entering configuration mode
Users currently editing the configuration:
  root terminal u0 (pid 2874) on since 2014-09-18 12:51:23 CEST, idle 00:05:57
      {master:0}[edit]
fpc0:

Exiting configuration mode
lab@ubuntu:/home/pubftp$

{master:0}[edit]
root@ex4200# show | compare rollback 1    
[edit interfaces ge-0/0/17]
+   description TEST;

{master:0}[edit]
root@ex4200#

If this worked for you please flag my post as an "Accepted Solution" so others can benefit. A kudo would be cool if you think I earned it.

cli -c "edit;set interfaces ge-0/0/17 description TEST;commit;exit"

 This is exactly what i was looking for. Thanks so much! The part about putting it into a script and running it from ssh is brilliant and will make this even faster!
