how to estimate `max_loops`?

Hi!

So, according to this, the max_loops parameter is used inside the send_command as a while bound before exiting. Inside the while loop one can see that:

loop_delay=0.2
[...]
while i <= max_loops:
     [...]
     time.sleep(delay_factor * loop_delay)

This means that the maximum total time is max_loops * delay_factor * 0.2.

Now, let’s say that I want to establish a maximum timeout for reading of 400s. Then max_loops=400/(0.2*delay_factor). With delay_factor=0.5 this leads to max_loops=4000.

However I’ve tried limiting this but even though I’ve set max_loops=4000 (or maximum time of 400s) I still can run show commands for over 500s. Why is this happening?

Finally, I’ve seen also that max_loops is used in send_config_set() but there is no while-loop inside send_config_set(). How does it work in here? Is my estimation above still valid?

Regards!

FYI, Netmiko 4.x also has a new send_multiline and send_multiline_timing feature where you can send in a list of commands and get the output for each of those commands.

You can see some examples in the test code here:

Fair enough…just don’t ask questions of the form I am using send_config_set() for show commands and it is not working properly. 😃

This equation does not apply for send_config_set() i.e. that only applies to send_command.

max_loops = myTimeOut / ( 0.2 * delay_factor )

I am probably going to completely remove max_loops from send_config_set() in Netmiko 4.X. It was used for a different purpose and was probably very rarely used and was being deprecated anyways.
