I've created a custom device to support my Juniper SRX gateways because the Juniper.Router's CLI.SendCommands seemed to fail (configure gives command error) and the
CLI.ModifyConfig said it wasn't yet supported. The problem I have is when I send it commands, times out waiting for an echo of the commands. The commands take (configuration modifications) but the script takes way too long and ends with a failure. How can I disable the waiting for an echo?
Meta command may be what you need to send along with your CLI command. Take a look at the online Help file here:
Probably want to experiment with the %ctUM: EchoOff and the %ctUM:Timeout xx meta commands.
