ERROR: netbox_importer: Error when polling device Nx5548U-SSC: Search pattern never detected in send_command

[gerardocastaldo]

Hello, when i execute the netbox importer i receive an error. I think that the error is due to a check of the hostname of the devices in prompt.

Could you help me to fix the problem ?

Pretty sure this is an issue with the "Transport Layer", (NAPALM -> netmiko).
Are you sure the NAPALM driver you are using works? What if you use nxos instead of nxos_ssh?
