netmiko.exceptions.ReadTimeout:
Pattern not detected: '[>#]' in output.
Things you might try to fix this:
1. Adjust the regex pattern to better identify the terminating string. Note, in
many situations the pattern is automatically based on the network device's prompt.
2. Increase the read_timeout to a larger value.
You can also look at the Netmiko session_log or debug log for more information.
