Hello, i have 2 switches. I wanted to run a command (show arp) and check a
specific output if exist or not on both. Then, i wanted to run a command
(show arp) and display the output.
The problem is that since the output i'm inspecting on first task doesn't
exist on switch1 .... the next task (Display Output) is not performed for
switch 1..... i don't know why this dependency. I thought that there
shouldn't be dependencies between tasks this way. How to overcome?
