The following EXPECT script is giving me problems and only working for one Iteration. It is giving me the TIMEOUT message as soon as it executes the loop one time. My requirement is to allow the script to run for n number of loops.

Can anyone please suggest what mistake i am making?

Expect with function

Hi,

Try below things.

Code:
#!/usr/local/bin/expect --
set timeout -1

        set switch_ip [lindex $argv 0]
