I'll post link for it when I get to it later today.

I am looking script which will run below command on cisco switch and provide output
#Conf t
(Confg)#ip http client connection foreclose
(Config)#end
#sh ip http client all

this I want to run on multiple IP and want to create an output file for all file can I use script shown

Try this this.

It calls a host_file.txt which you will need to create for your hosts. Its also assuming you are connecting to cisco devices, there's also the assumption you are connecting with a common user name and password for all devices. You will probably need to tweak it to meet your needs but it should do the job. If you want to test it out against the cisco devnet devices simply try running the script as is. I used the netmiko and I'm running python3.8. I would imagine anything after 3.6 would work.

Hi

I m just starting up in Network Automation. Could you please advise on the best method to push a whole switch config ( from a text file ) into a device ?

Any feedback would be much appreciated

Thanks

Typically if it's a new switch meaning not a replacement you would build the switch config manually and then manage from that point forward via automation. However if you have the config ready to go and the device is online and remotely reachable via ssh you could very easily push a config to it using netmiko. It's what I would recommend starting with. Check out this example on the netmiko GitHub page. https://github.com/ktbyers/netmiko/blob/develop/examples/config_change_file.py <https://github.com/ktbyers/netmiko/blob/develop/examples/config_change_file.py> Recommend poking around on this site. The guys great. He has many examples. The one I listed above is simply one of many options. https://pynet.twb-tech.com/blog/automation/netmiko.html Good luck.
