A Simple Python script to upload and verify (checksum) files to multiple Cisco NX-OS devices, with the support of Netmiko.

If you have a large number of NX-OS devices and need to upload a file, for example a new version of NX-OS, to all these devices without the help of an external tool like Cisco DCNM or similar, it can be very time-consuming. This script takes care of everything.

Requirements: All you need is Python and pip. Then, with pip we will install Netmiko and dependencies.

Installation:

$ git clone https://github.com/jerome-t/nxos-scp-upload.git $ sudo pip install -r requirements.txt 

Update the file hosts.txt with the list of your NX-OS hosts, one host per line.

Example:

host01.example.com host02.example.com 

Add the file name as an argument to the script. Then, the script will check if the file exists, read the list of hosts and ask you for your NX-OS credentials in order to upload the file. It will ask you for a confirmation before starting the upload. To save time and bandwidth, if the file already exists it will be not overwritten.

usage: nxos-scp-upload.py filename

positional arguments: filename The file to upload

Example where the file does not exists on the first host, but exists on the second:

$ ./nxos-scp-upload.py testfile.txt ================================================================================ Please, confirm the upload of: testfile.txt on: n9300-testA.example.com n9300-testB.example.com Proceed? [n]|y: y -------------------------------------------------------------------------------- Please insert your NX-OS username: admin And your password Password: -------------------------------------------------------------------------------- Upload on: n9300-testA.example.com -------------------------------------------------------------------------------- Results for: n9300-testA.example.com File exists already: False File transferred: True MD5 verified : True ================================================================================ Upload on: n9300-testB.example.com -------------------------------------------------------------------------------- Results for: n9300-testB.example.com File exists already: True File transferred: False MD5 verified : True ================================================================================ List completed, goodbye. ================================================================================

A great way to make your repo easy for others to use is to provide a link to a DevNet Sandbox that provides a network or other resources required to use this code. In addition to identifying an appropriate sandbox, be sure to provide instructions and any configuration necessary to run your code with the sandbox.

--- To be completed ---

Provide details on steps to test, versions of components/dependencies against which code was tested, date the code was last tested, etc. If the repo includes automated tests, detail how to run those tests. If the repo is instrumented with a continuous testing framework, that is even better.

The MD5 check part need to be completed, it's not working yet.

Uploading files in parallel still needs to be added.
