1 year ago Just FYI, cDev.unlock() is something I added to see if thats the issue. But the timeout happens with or without it.

1 year ago Made some progress. Used lock = False option to avoid locking the config db.
cDev = IOSXR(hostname=aHost, username=uName, password=uPassWd, port=22, timeout=300, lock=False, logfile=file)
changed the _XML_SHELL command to 'xml echo format' (tried 'xml echo' too).
_XML_SHELL = 'xml echo format'
Now I am getting XML parse error

1 year ago I printed the response for the CLI. Looks like there are 2 XML declaration at the top. One for request and other for response. It is probably why XML parsing is failing.

Things you might try to fix this:
You can also look at the Netmiko session_log or debug log for more information.
Script is pretty simple
