Hello, This video can walk you through the process... http://www.youtube.com/v/6SgPyMp98-c&rel=0&autoplay=1 You can set this change on multiple devices. It is very dangerous if you push out a misconfiguration. I would suggest you try this on one device first to make sure you set the snmp passwords properly. You can then push the changes to all 250 devices. If you have any further questions please feel free to contact the GTAC for assistance. Regards, Doug Hyde Sr Support Engineer Enterasys Networks
