Nanda thank you for the reply
I will get you debug output tomorrow, when I'm at the office. What I'm attempting to do is use CatTools to make some minor changes to the configuration of our Juniper switches. Examples of these changes would be to go into each switch and delete a line that directs snmp trap messages to a destination host that no longer exists. The entire procedure to accomplish that consists of just a few simple lines of text after successfully logging in. For example:
> edit
# delete system snmp trap-group deadhost1 10.1.1.1
# delete system snmp trap-group deadhost1
# commit and-quit
> exit
The session log data for that is showing the same kinds of problems with 'unknown command', etc. that the original poster talked about. And I had already gone through all the tricks I could find in the CatTools device and action setup options, for nulling out CanTools trying to speak Cisco IOS type things, like 'set term length 0', etc.
