Install new image on C9500 with python

cxu21 — Sun, 13 Aug 2023 11:03:32 GMT

I try to install a new nxos image on the C9500 switch using python.

I am thinking of using netmiko to connect to the device and issue "install all nxos bootflash:nxos.newversion.bin". Ideally, there should have no intervention for the installation, but during the process, there is a step asking if I want to continue, is there a way to automatically enter Y to let the process proceed?

The send_input() method takes a string as a parameter, and it will send that string to the device. Example

net_connect.send_input('Y')

Hope this helps.

Thank you for the advice.

I could not find the send_input method online, but while search for it, I found kirk's example for expect_string which help to resolve the issue.

Thank you for your advice
