I have the following expect script which works for the most part. I have it connecting to a Cisco switch (eventually a couple hundred) and configuring syslog servers. It checks to make sure that buffering wasn't already configured and if it isn't, set it.
If "logging buffered" is set, the script works fine. However, if "no logging buffered" is present, the script dies early before saving the config.
