My G3SI and CMS server are on the same network segment. They both plug in to the same Cisco switch, one on port 2 and the other on port 3. Port 1 goes to our router so that others can get into CMS with CentreVu. My problem is, even though the G3SI and CMS are plugged into the same Cisco switch, and their IP's reflect that they are on the same segment, if our router goes down, they can't see each other anymore, and CMS stops taking measurements. I believe it is that the G3SI and CMS do not have the same netmask. Does anyone know how to assign a netmask in the G3SI?
