How do I execute multiple show commands using Nornir + Netmiko

[ktbyers]

I would probably make a custom Nornir task similar to this:

def netmiko_direct(task):

    list_of_commands = ["show ip int brief", "show ip arp"]
    # Manually create Netmiko connection
    net_connect = task.host.get_connection("netmiko", task.nornir.config)
    results_dict = {}
    for cmd in list_of_commands:
        output = net_connect.send_command(cmd)
        results_dict[cmd] = output

    # You also could make a more formal Nornir Results object
    return results_dict

It is similar to for loop, when I am using this it's giving me the same output that I am getting by using for loop. It is like running 1 command on all devices and then 2nd command on all devices. I want to run all the commands in a single connection, 1st device and then 2nd device.

def get_config(task):
    try:
        #for command in showcommnads:
            list_of_commands = ["show ip int brief", "show clock"]
            net_connect = task.host.get_connection("netmiko", task.nornir.config)
            #results_dict = {}
            for cmd in list_of_commands:
                output = net_connect.send_command(cmd)
                print(output)

So you want all of the commands run on device1 first and then all the commands run on device2 after all the commands are finished on device1?

Hi Kirk, Did you get an answer for your comment on Jan 13th 2021? I too want to know how to execute multiple show commands for each device. One output per device.
