link didn't work i want a tool or an idea to make it

At exactly the same time or just as quickly as you can cycle through all the routers?

Do you need resulting output of command?

Do you know ahead of time the command should be run, or is this we need to run it now?

Will command break any remote session connection?

not important in the same time but i have 200 routers i want to run the command clear crypto gdoi then yes becouse the cisco ip phone some time not registered and i have to run this command on every single router to register ip phone and it waste the time i want a tool or idea to run this command specifically on all routers faster 

[Joseph W. Doherty]

Is there anything that can be "check" on the routers, themselves, that would show the need for this command?  If so, perhaps an EEM script could self monitor and apply the command as needed.

If not, might be able to write an external program that access each router and applies the command.  Execution could be sped in the controlling program can access multiple routers concurrently and/or doesn't need to wait on the results of the remotely executed command.  (NB: in the past, I've written both PERL and Python scripts to make changes to hundreds of routers.)

Lastly, there might be some management application that could perform a role similar to what I just described, but if so, I'm not current on what's in the marketplace.

Run the script by executing: python sshclient.py. 

Here is an example with config_file.txt has contents:

enable

cisco

show clock       

[dafrey@CrashCart functions]$ python sshclient.py

any answer please for my previous replay ??

This is from a linux system to run a script in python 2.7 interactive mode.   I am not sure if this is the same for windows.

[dafrey@CrashCart ~]$ cd /biz/python/bin/functions/

[dafrey@CrashCart functions]$ ls -l sshclient.py 

-rwxrwxrwx 1 root root 1233 Aug 30 09:34 sshclient.py

[dafrey@CrashCart functions]$ python
