I tried use script to change same configuration on my switches, but I received error like that:

Username and password are ok, I can connect from my computer without problem.  



# Script-Filter:
# $Vendor eq "HP"

import requests, json, re

# This values will be provided by NetMRI before execution
defaults = {

"http_password": http_password,

# Create NetMRI context manager. It will close session after execution

with NetMRIEasy(**defaults) as easy:
  easy.send_command('show version')

I work with a variety of network device brands, including HP/Aruba (procurve). When I get the "No authentication information found for device" error, it is because NetMRI does not know (discovery process has not determiend) the CLI credentials for the device.


One way to check: Under the Network Explorer > Discovery tabs, find the device and check the "S" (SNMP credential status) and "C" (CLI credential status) columns. They need to be green check boxes for NetMRI to function properly. In this case it is the "C" column you care about.


Another way to check:  Open the device viewer for that device. On the right under "settings & stats" pick "CLI credentials" and you can review what credentials have been tested and found to work/not-work for that device. You need at least one found to be good...and for that to populate the top fields above the list (and you can use "show password" button to show it, and "test" to test it).
