What type of device are you connecting to, and which activity are you using?
I am using the cli.send commands activity and the devices are Enterasys/Extreme S series switches.
When setting up SNMP for this, their is a requirement that you enter the passwords.
set snmp user test authentication sha encryption aes privacy
After which it will ask:
Please enter authentication password:
Please re-enter authentication password:
Is any anyway to setup a script where it responds with the correct details?
