// next call is going to print the result on screen

}
In this code, I wish to run command "tftp 10.8.61.116 put vrpcfg.zip Hostname.zip" in every switch , Hostname stands for every switch 's management ip address . I know we can use f'tftp 10.8.61.116 put vrpcfg.zip {task.host.hostname}.zip' in nornir in python but I don't know how to do in gornir . Could you provide any idea ?
