Unrecognized command on CE6850

[rgrueebler]

Hi

I use a Huawei CE6850-48T4Q in my lab and try to replace the config with the nornir-napalm plugin.

result = device.run(task-napalm_configure, filename='test.cfg', replace=True)

I get the error message:

Unrecognized command found

The reason for that is, that this switch does not support the 'display system file-md5' command. I assume that it is used to check if the config file was correctly transmitted to the device's flash.

def _get_remote_md5(self, dst):
        command = 'display system file-md5 {0}'.format(dst)
        output = self.device.send_command(command)
        filename = os.path.basename(dst)
        match = re.search(filename + r'\s+(?P<md5>\w+)', output, re.M)
        if match is None:
            msg = "Unexpected format: {}".format(output)
            raise ValueError(msg)
        return match.group('md5')

I know that this switch is quite old and uses an old firmware. I don't have a newer one to check if this command is available there. Is there a possibility to replace the config on older models?

Thank you
